A superb pair of modernist sterling silver cufflinks by Danish master Niels Erik From. The large domed faces center beautiful amber cabochons with strong deep reddish overtones. The amber is surrounded by a border of black patinated silver that contrasts beautifully with the natural silver and the amber. The backs are fully hallmarked for N. E. From with the marks used after 1966.

Origin: Denmark, ca. 1970. Condition: excellent. Size: 1” diameter. Weight: 17.2 grams.

A superb pair of Austrian Art Deco cufflinks, worked in 18K yellow gold. The round faces are centered with moonstone cabochons surrounded by round mixed-cut rubties. The moonstones have fine bluish color and strong adularescence that contrasts beautifully with the richness of the rubies. The rubies are natural and show no signs of heat treatment. The stones are graded as medium-dark, vivid strong purplish red with eye-clean to slightly included clarity. The faces are joined by chains to baton-style backs. The combination of moonstone and ruby was particularly popular during the first quarter of the 20th century, but it's rarely seen with an effect as pleasing as this. Both cufflinks are hallmarked with Austrian hallmarks used in the provinces near Dresden from 1922 until 1925.

Origin: Austria, 1922-25. Condition: excellent. Size: 17/32" diameter. Weight: 10.9 grams. Approximate Total Gemstone Weight: moonstone, 3.4 cts; ruby, 1.43 cts.

A nice pair of vintage “Sputnik” earrings set with citrines. This style was popularized by H. Stern in the 1950s as a way to show of the company’s unparalleled access to the world’s finest colored gemstones. The design eventually became known as “Sputnik” because of the perceived resemblance to the Soviet satellite active during the early years of the space race. Generally, Sputnik pieces were set with multi-colored stones, but occasionally a piece turns up set only with one stone, as in this case. The citrines have medium-dark, strongly saturated yellowish-orange color that contrasts beautifully with the more yellowish color of the gold mountings. Marked 14K.

Origin: America, ca. 1960. Condition: excellent. Weight: 9.5 grams. Approximate Total Gemstone Weight: 9.92 carats. 15/16" in diameter.

An extraordinarily fine pair of late Victorian or early Edwardian 18K yellow gold cufflinks, the faces in the form of navette-shaped buttons carved from crystal opal. The faces are accented with silver “stitches”, each accented with a five small rose cut diamonds. The opals have clear body color and the play-of-color is predominantly shades of green and blue with occasional flecks of orangy-red. The faces are connected by gold chains to gold torpedo backs. The use of carved opal as a button motif is most unusual, as is the use of crystal open rather than the more common white opal. The overall effect is subtle and very sophisticated. Tested and guaranteed 18K gold.

Origin: Continental Europe, ca. 1900. Condition: excellent. Size: 13/16” x 5/16”. Weight: 4.8 gr.

A heavy pair of 18K yellow gold and diamond cufflinks in the “Signature” or “Signature X” pattern by Tiffany & Co. This classic design was created in 1992 and is no longer available at Tiffany. The arms of the X are set with single-cut diamonds (I color, VS2 clarity). The toggle backs are marked “Tiffany & Co. 1992 750”.

Origin: America, 1992. Condition: excellent. Size: 17/32” x 17/32”. Weight: 14.9 grams. Approximate Total Diamond Weight: .63 ct.

An extremely rare and very important 18K yellow gold ring set with a white pearl and a black pearl designed by Jean Dinh Van for Pierre Cardin. The design features a squared shank with a flat open gallery enclosing the two 7.0mm pearls. The pearls are drilled and rotate freely on their axes. The pearls are of very nice quality with superb luster and natural color. The back of the shank is fully stamped with French 18K gold hallmarks and the interior is signed "Pierre Cardin".

Jean Dinh Van is one of the most important modernist French jewelers. He apprenticed at Cartier before starting his own studio in 1965. Dinh Van collaborated with most of the most avant-garde fashion designers of the era, including Pierre Cardin and Paco Rabanne. This design, created in late 1965 or early 1966, was Dinh Van's first independent commission and represented a major milestone in modern French jewelry. The simplicity and squared-off outline that eventually became his signature are already in clear evidence.

An example of the ring is included in France's permanent national jewelry collection housed at the Musee des Arts Decoratifs in Paris. It is also illustrated in "La Collection de Bijoux du Musee des Arts Decoratifs a Paris", "Jewelry & Metalwork in the Arts & Crafts Tradition", "European Designer Jewelry" and "Dictionnaire International Bijou".

Origin: France, ca. 1965. Condition: excellent, all original. Finger Size: 5. Dimensions: shank, 1/8" thick; 3/4" wide. Weight: 5.25 grams.

A heavy 18K yellow gold egg-shaped fob charm decorated with ornate beading and twisted wirework in the Victorian Etruscan Revival style. The fob is further enhanced with oval and round coral cabochons. The coral is the intense orangey-red shade displayed by coral along the Mediterranean coast. Unlike most fob charms of this type, this example is hinged and opens to serve as a small container. In Victorian times, such a container would have held a small pad soaked in perfume so a lady wouldn't have to endure the smells on the streets. Marked “750” for 18K gold.

Origin: Italy, ca. 1960. Size: 1-3/8” long (excluding jump ring). Weight: 13.6 grams.

A very heavy pair of 18K yellow gold stirrup cufflinks retailed by famed New York jeweler Olga Tritt. Stirrup or “étrillé” cufflinks were popularized by Cartier in the 1940s and have appeared in many variations since. This pair is unusual because of the width of the gold mesh and their relative weightiness. The closing mechanism is a bit more decorative than most, even though it can’t be seen when the cufflinks are in place. The mechanism is marked with a French jeweler’s mark indicating 18K. The cufflinks are presented in their original box, the inside of the lid imprinted with Olga Tritt’s logo and Park Avenue address.

Origin: France, ca. 1970. Condition: excellent. Size: 1” x 7/8” x 5/16” wide. Weight: 25.0 grams.

A wonderfully naughty Art Nouveau 18K yellow gold ring depicting a couple engaged in mutual oral stimulation. Victorian and Edwardian erotic jewelry is extremely rare, having been made only for the daring few who were willing to wear such things in public. Like other pieces of erotica, the designer was charged with making the object look as innocent as possible, only revealing its true nature upon very careful and prolonged inspection. Upon first examination, this ring appears to be a typical sinuous floral Art Nouveau design. Looking closely however, the design reveals a man and woman amorously entwined. Even the back of the shank is decorated with a pair of somewhat cleverly concealed penises. The ring is marked with French hallmarks for 18K gold.

Origin: France, ca. 1910. Condition: excellent, very little wear. Size: 1/2" wide. Finger Size: 8-3/4. Weight: 7.5 grams.

A nice vintage tie bar in a bamboo pattern by Tiffany & Co. The bar is worked in 14K yellow gold, and each end features a blue sapphire cabochon collet set in platinum. The small amount of platinum contrasts nicely with the deep blue of the sapphires. The bamboo design was reworked in the 1960's and became one of Tiffany's most successful sterling silver flatware designs. Its use in jewelry, however, is uncommon. The relatively short length works perfectly with the narrow width of today's ties. The back is marked "Tiffany & Co. 14K."

Origin: America, ca. 1945. Condition: excellent. Size: 1-15/16" long. Weight: 6.1 grams. Approximate Total Gemstone Weight: .34 ct.

An extraordinarily fine antique 18K yellow gold ring by Tiffany & Co. set with a mixed cushion cut Burmese blue sapphire surrounded by old mine cut diamonds. All the gems are of the finest quality. The sapphire has been certified by the American Gemological Laboratories (see the following paragraph). The diamonds, ranging in size from approximately .22 carat to .29 carat each, are estimated at G/H color and SI to VVS2 clarity. The sapphire is set in a prong setting, while the diamonds are set in a shared-prong setting that creates a filigree appearance around the back of the crown. The shoulders of the shank are lightly decorated with beaded engraving.

Nearly all sapphires marketed in the last 150 years have been heated to improve the color. This is considered a standard practice. Other treatments, such as filling in fractures, altering the color family, etc., though considered bad practice, are nonetheless quite common. Fine Burmese stones from the Mogok region that have not been treated in any way are exceedingly rare and only show up in upscale jewels from makers such as Tiffany and Cartier. This particular stone, with its bright coloring and beautiful cut, is nothing short of stunning.

The AGL Brief (dated April 2008) indicates that the sapphire is natural; displays specific properties and characteristics associated with stones from Burma; measures 7.39 x 6.69 x 5.82 mm; weighs 2.49 carats; is cut in mixed cushion, has blue color, and shows no heat or additional treatments. The brief further indicates that unheated sapphires are scarce. The original brief will accompany the ring.

Origin: America, ca. 1890. Condition: excellent, all original, interior of shank has a period monogram. Finger Size: 4-1/4 (The ring can be sized up and we would recommend that the work be performed by Tiffany). Weight: 6.0 grams. Gemstone Weight: diamond (estimated by measurement), 2.25 carats; sapphire (by actual weight), 2.49 carats.

A very attractive pair of Art Deco 14K white gold cufflinks, the rectangular faces set with plaques of rich translucent green chalcedony. The white gold borders are enhanced with engraving. Art Deco cufflinks set with green stones are difficult to find. The connectors are marked "14K".

Origin: America, ca. 1920. Condition: excellent, all original. Size: 1/2" X 13/32". Weight: 3.9 grams.

An important 19th century brooch of carved coral lilies nestled among 18K yellow gold chrysanthemum leaves set with old mine cut diamonds. The lily blossoms are fully three dimensional and are carved from the finest Mediterranean red coral, most likely harvested from the Italian coast near Naples. The heavily detailed gold leaves have a strong sculptural quality with undulating movement. Every surface is set with old mine cut diamonds of exceptional quality, averaging I/J color and SI clarity. Diamonds, collet-set and suspended from knife-edge mountings, also form the flowers' anthers. Diamonds are also set into portions of the stem that can't be seen from the front. Exposed areas of gold are delicately hand-engraved. The back of the brooch retains its original extended pinstem c-clasp. There is also a threaded aperture that was probably originally used to attach the brooch to a comb so it could be worn as a hair ornament. Tested and guaranteed at least 18K (it appears to be a little higher, perhaps 19-20K).

Origin: probably France, ca. 1870. Condition: excellent; one gold stem appears to have an old repair; no breaks in coral; no replacements. Dimensions: 3" x 3-5/8" x 1-1/8". Weight: 54.9 grams. Approximate Total Diamond Weight: 10.0 carats.

A very fine pair of late Edwardian/Deco transitional cufflinks, the 14K yellow gold faces set with scissor-cut citrines, amethyst and green tourmaline. Each of the stones fits into a gallery beautifully engraved in a scrolled motif. Most unusually, instead of traditional prongs, the stones are held in place by lozenge-shaped plaques of platinum, each set with a small rose cut diamond. The stones have very attractive color and excellent clarity. The connectors are removable. Tested and guaranteed 14K gold and platinum.

Origin: America, ca. 1915. Condition: excellent, all original. Dimensions: faces, 9/16 x 7/16". Weight: 8.7 grams. Approximate Total Gemstone Weight: citrine, 6.36 cts; amethyst, 3.17 cts; tourmaline, 3.68 cts; diamond, .08 ct.

An absolutely stunning Art Deco cross pendant in 18K yellow gold accented with diamonds and sapphires. The body of the cross is worked in pierced yellow gold, centering a nearly 2/3-carat round old European cut diamond collet-set in platinum. The piercing lightens the appearance of the cross and creates the visual effect of rays emanating from the central diamond. Each of the four arms of the cross is bordered with caliber-cut natural blue sapphires of fine quality, and terminates in a band of round brilliant-cut diamonds bead-set in platinum. The corners of the junctions of the arms are ornamented with small diamonds collet-set in platinum and cabochon sapphires prong-set in gold. The overall design is very angular, heightening the strong Art Deco treatment of this most traditional of designs. The center diamond is estimated at G color, SI2 clarity, and the smaller diamonds are of similar quality. The sapphires have excellent color saturation and clarity. This is, without a doubt, the finest Art Deco cross we’ve seen. The cross is stamped with the French “tete d’aigle” for 18K gold and has an indistinct maker’s mark.

Origin: France, ca. 1925. Condition: excellent, all original. Size: 2” x 1-9/16” (excluding bale). Weight: 11.5 grams. Approximate Total Gemstone Weight: diamond, 2.5 carats; sapphire, 3.6 carats.

A classic, heavy pair of sterling silver cufflinks by Hermes. Each sphere is enhanced with multiple engraved letters, randomly arranged. The letters—“H”, “E”, “R”, “M”, “E”, and “S”—are those found in “Hermes”. The connectors are slightly arched so the sphere lay tightly against the cuff. Each cufflink is signed “Hermes”, is marked “925” and bears the French “tete d’Athene” mark for sterling silver and the silversmith’s hallmark. This vintage design is no longer available at Hermes.

Origin: France, ca. 1970. Condition: excellent, all original. Size: spheres, 3/8” diameter. Weight: 25.1 grams.

A fine and large pair of 18K yellow gold and multi-stone Sputnik earrings by H Stern. This classic modernist design features goldn domes studded with various colored gemstones including green tourmaline, pink tourmaline, amethyst, aquamarine, citrine and garnet. Each piece of Sputnik jewelry has a unique appearance depending upon the combination and arrangement of the gemstones. The design was created specifically to show off the range of colored gemstones from Stern’s Brazil mines, but it quickly came to be known as “Sputnik” because of its spiky resemblance to the 1960’s Soviet satellite. The clips are marked with an older Stern hallmark. The earrings have their original clips and never had posts. Posts could easily be added. Marked “750” and “18K”.

Origin: Brazil, ca. 1970. Condition: excellent, all original. Size: 15/16” diameter; 1/2” high. Weight: 10.8 grams. Approximate Total Gemstone Weight: 9.79 cts (green tourmaline, 2.67cts; citrine, 2.29cts; aquamarine, 2.09cts; pink tourmaline, 1.58cts; aquamarine, .70cts; amethyst, .46cts).

A rare pair of 18K yellow gold earclips in the Sputnik style. The domes are bezel-set with round amethysts, citrines, aquamarines, and green and pink tourmalines. This design was created in the 1950s to highlight the range of colored gemstones available from the mines of Stern's native Brazil. It later came to be called "Sputnik" for its resemblance to the spiky Soviet satellite launched in 1957. Each piece has a unique appearance that relies on the particularly selection and placement of the gemstones for its overall look. This example trends toward mid-tone colors, neither too intense or pastel. The earrings are unmarked, as were many Stern pieces of the period. Tested and guaranteed 18K.

Origin: Brazil, ca. 1955. Condition: no dings or chips to stones; replaced posts. Dimensions: 13/16" diameter. Weight: 10.2 grams. Approximate Total Gemstone Weight: 10.3 cts.

A nice pair of vintage 14K yellow gold cufflinks, each in the form of a large and a small button, complete with raised gold beads to suggest the stitches. The faces are connected by chains. Tested and guaranteed 14K.

Origin: America, ca. 1980. Condition: excellent. Size: 3/4” & 9/16” diameter. Weight: 11.5 grams.

An extraordinary gentleman's dress set comprising two double-sided cufflinks and three shirt studs, all worked in 18K yellow gold and set with cabochon cut blue sapphires. The design is very simple and sophisticated. The sapphires are of unusually fine quality to be cut en cabochon. Using the Gemological Institute of America's grading system, they are medium-dark, vivid strongly violetish-blue with excellent symmetry and polish, and very good clarity. The set was retailed by Cabochon Jewellers, Bangkok's most luxurious jeweler, located in the lobby of The Oriental Hotel. The set is accompanied by two original bills of sale, indicating the weight of the gemstones. Each piece is marked "750" for 18K.

Origin: Thailand, ca. 1978. Condition: excellent, all original. Size: cufflinks, 9/16" x 15/32"; studs, 1/2" x 13/32". Weight: 24.9 grams. Approximate Total Gemstone Weight: 15.51 carats (cufflinks, 9.53 cts; studs, 5.98 cts).

A stunning 19K yellow gold enhancer pendant intended for a thick chain or a strang of beads by Elizabeth Locke. The oval pendant encloses a gorgeous labradorite cabochon glowing with the billowy blue color of the best labradorite. The central stone is accented at compass points by round brilliant-cut blue sapphires. The sapphires have a slightly violet tint and exceptional brilliance. The bail is hinged so the pendant can be slipped over a thick chain or onto a strand of beads or pearls. The interior of the bail is has Locke’s signature and is marked “19K”. The pendant is presented in its original Elizabeth Locke silk pouch. A similar pendant currently retails for $3,600.

Origin: America, ca. 2010. Condition: excellent. Size: 1-1/2” x 3/4”. Weight: 10.6 grams.

A rare pair of Art Nouveau 14K yellow gold bean-back cufflinks, the oval faces with repousse decoration representing Poseidon (“Neptune”), god of the sea. The god is identifiable by the trident that forms his crown. The background at first appears to be a simple stippled pattern, but careful examination shows that the background is actually worked in a very fine pattern of fish scales. Mythollogical subjects were very popular in men’s jewelry at the end of the 19th century, but this is the first time we’ve seen cufflinks with the image of Poseidon. The bean backs are marked by an unidentified American maker and are stamped “14K”.

Origin: America, ca. 1880. Condition: excellent, sharp detail, no dings. Size: 11/16” x 1/2". Weight: 5.3 grams.

A lovely Art Nouveau pendant worked in silver and 10K yellow gold. The pendant consists of an openwork triangular silver plaque with a pair of plique-a-jour enameled mistletoe leaves below a band of opals and above a band of brilliant green moldavites, themselves over a square-cut pink tourmaline suspending a semi-baroque pearl drop. The whole is suspended from a round brilliant cut pink tourmaline set in gold. The combination of colored gemstones is lovely and nicely accents the enamel. The opals have a particularly nice play of color in tones of blue and reddish-orange. The overall design strongly suggests the work of the Pforzheim studios in Germany, but the “Sterling” markings on the back indicate an American origin.

Ca. 1900. Condition: excellent; no enamel damage. Size: 1-5/16” x 2” (to top of bale). Approximate Total Gemstone Weight: tourmaline, .96 ct; opal, .33 ct; moldavite, .20 ct. Weight: 4.4 grams.

A very fine five-piece 14K yellow gold and sapphire dress set by Van Cleef & Arpels. Each piece is fashioned as a reeded baton circled by a collar of channel-set blue sapphires. The sapphires are of superb slightly violetish-blue color, with medium tone and vivid saturation. One baton on each cufflink is hinged for ease in putting them through the cuff. Each shirt stud is signed "VCA NY", and is stamped with the serial number and "14K". The cufflinks are marked only "14K". Van Cleef employed several jewelers to manufacture their designs during this era, and it's not uncommon to find sets in which not every piece is marked by VCA.

Origin: America, ca. 1940. Condition: excellent. Size: cufflinks, large faces, 15/16" long; small faces, 7/8" long; studs, 9/16" long. Weight: 24.8 grams. Approximate Total Sapphire Weight: 2.37 carats.

A lovely Art Nouveau 14K yellow gold honeymoon pin in the form of a pearl-studded horseshoe enclosing a beautifully-enameled violet. The petals are worked in realistic shades of purple fading to pinkish-cream at the centers and the flower is accented with a bright green leaf. In the Victorian language of flowers, the violet was used to symbolize faithfulness. Combined with a horseshoe for good luck, a pin of this sort almost certainly would have served as a going-away gift. The original clasp is stamped 14K and has Krementz' hallmark.

Origin: America, ca. 1890. Condition: excellent, all original, no enamel damage. Size: 13/16" x 3/4". Weight: 3.3 gr.

A magnificent pair of Art Deco 18K white gold earrings set with diamonds and Burma rubies. The oval brilliant cut rubies have pure, vivid red color and good clarity. The do not show indication of heat or other enhancement. The rubies are surrounded by a border of round diamonds intersected by a double band of diamonds on either side of the ruby. These hang freely from a surmount fashioned by a trilliant cut diamond suspending round diamonds set into a triangular plaque echoing the shape of the trilliants. The mountings have a double gallery and the backs surrounding the ruby drops are engraved in a geometric pattern. The .21-ct trilliants are graded as E color, SI1 clarity and the smaller diamonds are G-H color, SI1-I1 clarity. Tested and guaranteed 18K.

NOTE: We are presenting the matching ring (Item #1306951).

Ca. 1925. Condition: excellent. Dimensions: length, 1-3/8"; maximum width, 1/2". Weight: 4.5 gr. Approximate Total Gemstone Weight: ruby, 2.5 cts; diamond, 1.74 cts.

A very attractive 18K yellow gold ring in the Retro Moderne style set with an emerald cut synthetic pink sapphire enclosed at either end with a pair of square cut synthetic rubies and a natural round brilliant cut diamond. The stones are set in an ornate scrolling mount. The colorful design, with its strong contrasts, makes for a very attractive, fun ring. Synthetic rubies and sapphires were frequently used during the Retro period, even by the most exclusive jewelers, because many stones were unavailable to World War II. Tested and guaranteed 18K.

Origin: America, ca. 1940. Condition: excellent; the ring has been sized up. Dimensions: crown, 20mm x 10mm; back of shank, 5mm. Finger Size: 6-1/2. Weight: 9.2 gr. Approximate Gemstone Weight: diamond, .10 ct; synthetic ruby, .66 ct; synthetic pink sapphire, 6.18 cts.

An exceptionally fine Victorian 18K yellow gold and turquoise locket in the Etruscan Revival taste. The outside of the sphere is encrusted with ornate wirework decoration against a stippled background. Small Persian turquoise cabochons, some set in star-shaped mountings, add a touch of color. The clasp is cleverly hidden to be nearly invisible when the ball is closed. Indistinctly marked; tested and guaranteed 18K.

Origin: England or America, ca. 1880. Condition: excellent, all original. Dimensions: 7/8" diameter (excluding bail). Weight: 11.2 grams.

A delightful vintage 14K yellow gold disc charm or pendant by Tiffany & Co. The center features an intricately cast "Tree of Life" bedecked with gemstone flowers. Starting with the diamond and spiraling outward in a counterclockwise direction, the first letter of each gemstone’s name—Diamond, Emerald, Amethyst, Ruby, Emerald, Sapphire and Topaz—spells “DEAREST”. The tree is enclosed in an open twist border, in turn enclosed in a broad “pleated” border. The back is marked “Tiffany & Co. 14K”.

Acrostic jewelry spelling out such sentiments was very popular in the Victorian era. The gemstones are 19th century antique cuts and Tiffany apparently custom-set them in this piece at a client’s request. The nature of the clarity characteristics suggests that the ruby is Burmese in origin, while the sapphire is Kashmir. Neither shows evidence of treatment, nor are the emeralds filled. The “Tree of Life” pattern was often set with birthstones representing the owner’s children or grandchildren, but the acrostic “DEAREST” is most unusual.

Origin: America, ca. 1950. Condition: excellent. Size: 1-5/8” diameter. Weight: 17.8 grams. Approximate Total Gemstone Weight: .35 ct.

A really beautiful pair of double-sided Edwardian 14K white gold cufflinks, the round faces ornately pierced in design reminiscent of the rose windows in Gothic cathedrals. One face of each pair is centered with a pale blue sapphire that contrasts nicely with the surrounding white metal. The cufflinks take on a wide range of appearance depending on the color of shirt fabric showing through the piercing. The connectors are hallmarked by Taylor & Co.

Origin: America, ca. 1915. Condition: excellent. Dimensions: 9/16" diameter. Weight: 5.3 grams.

An exquisite Edwardian pendant and brooch featuring a large oval rubellite (pinkish-red tourmaline) cabochon surrounded by old European cut diamonds mounted in elegant buttercup settings. The diamond flower buds are mounted in an intricately interlaced knife-edge platinum setting. The back has a removable mounting so the piece can be worn as either a brooch or a pendant. Removable mountings of this type are very complex and appear on only the finest pieces from the period. The rubellite has fine color. Rubellites are usually very included, but this stone has far better clarity than most, graded as Type III slightly included. The diamonds range I-J in color and SI1-SI2 in clarity. Tested and guaranteed platinum.

Origin: probably France, ca. 1905. Condition: excellent, all original. Size: Weight: 6.6 grams. Approximate Total Gemstone Weight: diamond, 1.6 cts; rubellite, 5.08 cts.

A wonderful Art Deco 14K yellow gold baton-link long chain, studded at intervals with oval moss agate cabochons. The long chain was a traditional Victorian style, but in this case was updated by replacing the usual small links with long baton-style links. The resulting linear look would have been considered much more modern and stylish. The links are interrupted by nine 7.5x9.0mm moss agate cabochons. The gemstones have very nice medium- to dark-green lacy moss-like inclusions against the colorless transparent background. Notice that the stones are set closer together toward the middle of the chain, and farther apart toward the ends. The clasp is marked “14K”.

Origin: America, ca. 1920. Condition: excellent. Size: 28” long. Weight: 18.9 grams.

A very fine pair of heavy 18K yellow gold and platinum double-sided cufflinks by David Webb. The round faces are shaped as compressed spheres (imagine an old-fashioned flying saucer) bisected by pairs of parallel raised bars. Each face is centered with a round brilliant blue sapphire bezel-set in platinum. The smaller, back faces are hinged so they can easily be put through a cuff. The gold and platinum have a very elegant brushed texture that contrasts beautifully with the sapphires. The sapphires are of the very finest quality, graded as medium vivid blue (B5/6). The clarity is eye-clean and the stones have not been subjected to heat treatment. The cufflinks are quite heavy. Each is marked "Webb" and "18K".

Origin: America, ca. 1970. Condition: excellent, all original. Dimensions: larger faces, 3/4" diameter. Weight: 25.8 grams. Approximate Total Sapphire Weight: 1.5 carat.

A classic pair of Art Deco sterling silver cufflinks by Gaetan de Percin, the jeweler responsible for most of the Hermes jewelry designs in the 1930s and 40s. This style, in the form of equestrian stirrups or "etrier" is a classic design created around 1940. Aside from Hermes, De Percin made variations of this design for prestigious houses such as Cartier, Van Cleef & Arpels, Tiffany, Chanel, Dior and Boucheron. The cufflinks are marked with French silver hallmarks and with the master's mark of De Percin.

Origin: France, ca. 1950. Condition: excellent. Dimensions: faces, 11/16" x 5/8". Weight: 15.7 grams.

An extremely rare 18K yellow gold bracelet in the Sputnik design by H Stern. The domes are bezel-set with round amethysts, aquamarines, citrines, green tourmalines, pink tourmalines and garnets. The design was created in the 1950s to showcase the range of colored gemstones available from Stern's mines in Brazil. It later came to be called "Sputnik" because of its resemblance to the spiky Soviet satellite launched in 1957. Each piece has a unique appearance that relies on the particular selection and placement of the gemstones. This bracelet has strong, saturated colors in autumnal hues. This design was made in earrings, pendants, charms, rings, brooches and bracelets; the bracelet is by far the most difficult piece to find. This bracelet is marked for 18K and is also marked with one of Stern's early hallmarks.

Origin: Brazil, ca. 1955. Condition: all excellent except one dome that has a ding around one of the stones (not particularly visible unless you're really looking for it). Dimensions: 27/32" wide; 7-1/2" long. Weight: 23.6 grams. Approximate Total Gemstone Weight: 18.34 carats.

An exceedingly rare Georgian 18K yellow gold pendant locket celebrating the first manned flight by the Montgolfier brothers from Paris in 1783. Hot air balloons were one of the scientific wonders of the late 18th century, and balloon designs were worked into furniture, textiles, clothing and jewels. This locket features a hot air balloon carved from a piece of mother of pearl and then decorated with gilding and realistic painted detail. The balloon is affixed to a pale blue silk background and enclosed behind convex glass in an 18K yellow gold frame bordered by a ropetwist motif worked in gold and natural seed pearls. The edges of the frame are further accented with a beaded ogee design and bright-cut stippling. The back of the locket, also glass covered, features a mother of pearl plaque painted with the initial "F.H.", also affixed to a blue silk background. A piece such as this would most certainly have been made-to-order, so it is not surprising that it is unmarked. Tested and guaranteed 18K.

The rarity of this pendant really cannot be overstated. Very little late 18th century French jewelry survived the Revolution and pieces with a Montgolfier theme are exceptional.

Origin: probably France, ca. 1785. Condition: excellent; a small piece of the balloon carving has become dislodged (probably from the top finial of the balloon) and slipped toward the bottom of the frame (the frame could be opened the the loosened piece reattached). Size: 1-7/8" x 1-5/8".
