A fine and ornate Victorian quadruple foxtail watch chain worked in 18K gold with rubies and bloodstone. Two slides, each with engraved floral decoration and set with cushion cut rubies, enhance the chain. The two slides are drawn close together so the chain plaits itself in the middle. One end of the chain terminates in a dog clip clasp. The other end terminated in a watch key and a fob seal decorated to match the slides. The fob seal is also set with rubies along the sides and ends in a bloodstone plaque (unengraved). The rubies have vivid color and show no indications of heat treatment. The chain, dog clip, key and fob are all marked individually with early 19th century French 18K gold marks. A chain this ornate would have been worn as a “gilletière” high on the vest so it would be readily visible to others. The chain would be lovely styled into a longer necklace with other chains.

A fine 10x19mm navettte-shaped opal set in an Art Deco 14K yellow gold setting enhanced with bright champleve enamels in shades of dark and light green, red, and black. The opal has a very nice "pinfire" pattern with an unusually generous amount of red/orange play of color. The pattern is evenly dispersed, with color throughout the stone. Unlike some of the other opal patterns, pinfire has the distinction of showing pattern when viewed from any direction. Even the bottom of the stone visible through the mounting has nice color and pattern. The colors of the stone are nicely accented with the enamels on the mounting. The shank is engraved in a floral pattern and is accented at the shoulders with floral appliques worked in white gold. The interior of the shank is marked "14K" and has an unidentified maker's mark.

A stunning pair of late Art Nouveau 14K yellow gold floral earrings, the petals enhanced with iridescent enamel and the centers set with clusters of blue sapphires. The quality of the enamel, shading from a medium blue to a pale greenish-yellow is superb. The gold surfaces underneath the enamel are delicately engraved to represent the veining and surface textures of real flower petals. The use of iridescent enamels and the quality of workmanship suggests one of the better Newark workshops as the likely maker. The round sapphires have vivid blue coloring and are set nicely above the surrounding petals to create a very three-dimensional appearance. The earrings probably originally had wire, but now have omega-clips. The could easily be returned to wire, or have posts added. Tested and guaranteed 14K.

Origin: America, ca. 1915. Condition: excellent; no enamel damage; omega clips replacing original wires. Size: 1-1/8” diameter. Weight: 13.1 grams. Approximate Total Gemstone Weight: sapphire, .84 carat.

A stunning Georgian floral pendant worked in silver-topped 18K gold. The radiating petals are studded with diamonds in the newly fashionable “a jour” or open settings that came into vogue around 1800. The selection of diamonds is a virtual history of early diamond cutting and includes rose cuts, Mazarin cuts, table cuts, and Peruzzi cuts. The flower is centered with an unheated cornflower blue sapphire, likely of Ceylon origin. The back of the setting is ornately engraved in a sort of starburst pattern. There’s a small hole in the back of the setting that would have held a long pin attachment so the piece could be worn as a hair ornament. The flower has been converted for wear as pendant with the discreet additional of a hidden bail. Tested and guaranteed 18K gold.

Possibly the finest Georgian fob seal we’ve seen, this example is worked in multicolored 18K gold. The large swivel features a carnelian plaque on one side that reverses to an amazing crystal-enclosed compartment. Inside the compartment is a three-dimensional fruit basket worked in yellow, white, rose, green and blue gold. The rock crystal cover is slightly domed to magnify the fruit basket decoration. The edges of the swivel are engraved “S Kip” on one edge and “S Kip Poe” on the other, suggesting it was perhaps a gift from a grandfather to a grandson of maternal descent. Women began wearing pocket watches in the 1780s, so it's also possible this fob was a gift from mother to married daughter. Tested and guaranteed 18K gold.

An extraordinary 18K gold and gemstone ring by H Stern in the brutalist style of the 1950s and 60s. The design ethic is evident in the jagged outlines, arching construction and jarring color juxtapositions. As with all H Stern jewelry of the period, the amethysts, peridots and hessonite garnets are of excellent quality. The gold surfaces are stippled for additional interest. This ring surpasses being mere jewelry, becoming architecture for the hand. The interior of the shank is stamped with Stern's hallmark.

A very fine 14K rose gold brooch mounted with a Scottish Terrier carved from banded agate. The dog's head is beautifully rendered, using the stone's natural banded coloring to represent the dark colored muzzle and ears that contrast with the brighter carnelian of the fur. The eyes are represented by small round cut demantoid garnets set in a manner that nearly completely hides the gold collets holding the stones. The workmanship of the carving is first-rate. The setting is rather simple an does not detract from the beauty of the hardstone carving.

Faberge was a leading creator of hardstone carvings, and used carvings created in his own workshops as the shops of others. In Paris, Cartier was determined to compete with Faberge and also produced hardstone carvings. The Cartier versions, however, tended to be a little less realistic and rarely relied on the natural color variations of the stone material. The coloring technique strongly suggests that this carving is the product of a Russian workshop contemporary with Faberge, and possibly that of the master himself.

There appears to be a rubbed-out hallmark on the back side. This is occasionally seen in Russian pieces that had their marks obliterated shortly after the Revolution as their owners tried to smuggle jewels out of the country. Tested and guaranteed to be 56 zlotniks (slightly purer than 14K).

Origin: Russia, ca. 1905. Condition: excellent, all original. Size: 2-9/16" x 1-1/16". Weight: 15.3 grams. Approximate Total Demantoid Weight: .1 ct.

A lovely French garland-style pendant/brooch in platinum and set with diamonds. The garland style, popularized by Cartier, heavily borrowed Louis XVI motifs such as bows, ribbons and laurel wreaths—all seen in this example. When worked in platinum, the designs take on a delicate appearance and allow the diamonds to shine. The center old European cut diamond, graded as J/SI1, weighs .48 carat. The diamond hanging from an articulated millegrained knife-edge mounting has the same grading and weighs .35 carat. The smaller diamonds are a mix of antique cushion, rose and Swiss cuts. This piece has two small loops at the top of the back so it can be worn from a fine platinum chain. When worn as a pendant, the 18K gold brooch fitting can be unscrewed and removed entirely. Convertible fittings such as this were difficult to make and always signaled a piece of high quality. The hallmarks allow the pendant/brooch to be definitively dated prior to 1912.

Origin: France, ca. 1910. Condition: excellent, all original. Size: 1-11/16” x 1-9/16”. Weight: 10.8 grams. Approximate Total Diamond Weight: 2.15 carats.

A wonderfully heavy vintage silver bracelet by Hermès. The bracelet has a triangular profile that stands well out from the surface of the wrist and a masterfully constructed so that it is flexible, but appears rigid when being worn.

The bracelet is presented in its original vintage fitted Hermès gray box. The bracelet is fully hallmarked with French first standard (950/1000 pure) silver marks and Hermès maker’s mark indicating it was made in the company’s own ateliers instead of being farmed out to other makers as was sometimes the case.

An oustanding sterling silver centerpiece basket by Gorham. The sides and handle are decorated with extremely ornate bright-cut engraving in a swirling foliate pattern.

An outstanding 18K gold pendant set with an amazing enameled alpine scene by Carlo Poluzzi (1899-1978), the greatest Swiss enamellist of the the 20th century. Poluzzi sometimes used the very difficult technique of applying translucent enamel over an engraved gold plate to produce brilliant sunrise or set effects as seen in the left side of the sky in this example. This required multiple coats of different colored enamels which increased the likelihood of unwanted cracks during the multiple firings. Poluzzi was perhaps the only enamellist capable of this technique in the 20th century, and indeed, the scene is signed at the lower left. Of course, this example is also signed at the lower left. In the 1920s, Poluzzi (still in his low 20s) became the master of Emaux de Genève, the provider of the highest quality enameled dials and cases for luxury horlogers such as Vacheron & Constantin, Patek Philippe, Rolex and Gubelin. This plaque is set as a pendant by the Gubelin. The Holbein-style setting features square cut rubies and emeralds amid swirling gold foliage. The gemstones are of very fine quality with intense, saturated coloring and excellent clarity. The reverse is stamped with Gubelin’s hallmark and the Swiss gold mark for 18K.

A magnificent set of cufflinks the five shirt studs worked in 18K yellow and white gold set with diamonds. The face of each cufflink and stud is formed as a white gold star surrounded by a foliate and beaded yellow gold border. The stars are set with brilliant round-cut diamonds of extremely fine quality, estimated at F color, VSI clarity. The outer gold edges have fine saw-pierced galleries. The backs of the cufflinks have a toggle closure and the studs have double-folding flanges. This set is most unusual in that it includes five shirt studs. The quality of workmanship is at a level of the most exclusive makers. The presence of five studs indicates that the set was probably a custom order, since most formal shirts have only three or four holes for studs. The advantage of the fifth stud, of course, is that if you lose one of the others you have a ready replacement! The yellow gold is intensely yellow—a shade not usually achieved below 20K. Each piece is marked “750” for 18K gold and is signed “DIF”.

A magnificent and extraordinarily rare tole tray depicting the surrender of the French army to the English following the Battle of the Plains of Abraham in 1760. The quality of painting is stunning. The two figures in the foreground represent General James Wolfe (in red) and the Marquis de Montcalm (in blue). Both generals died from their wounds within hours of the end of the battle, but the painter took artistic liberties by presenting them both in apparently good health. Montcalm passes his baton to Wolfe as a flag-bearer lowers the French royal flag to the ground as a gesture of defeat. British officers can be seen standing at attention behind Wolfe. A tent encampment appears in the background. The scene is enclosed within a gilt border. Toleware was popular in the late 18th and early 19th century, and this example was most certainly painted shortly after the famous victory, while British patriotism surged. The quality of painting, as well as that of the metal tray itself, is superb and shows the hand of a master. Scenic toleware, in general, is quite desirable, but a piece that illustrates such a pivotal event and in such a beautiful way is really beyond rare! The tray could be hung on a wall or could be custom-fitted with a base for use as a table.

Origin: England, ca. 1760. Condition: excellent, all original paint, less than 1% paint loss, a slight bend in the rim near the upper left corner. Size: 30-1/4” x 21-7/8”.

Exquisite 1950s triple strand pearl bracelet completed with generously diamond-set 14K white gold spacers and matching clasp. The 7mm pearls are of fine quality, with thick nacre and a lovely sheen, and are beautifully matched. The body color is ivory with silvery overtones. The quality is estimated at A1. Three swirled spacers and a matching clasp, each worked in 14K white gold complete the bracelet. Each piece is set with round brilliant-cut diamonds.

The matching clasp, completely invisible when closed, is one of the best clasp designs we’ve seen in many years. The back of the clasp is marked “14K”.

A stunning heavy 18K gold bracelet enhanced with ornate chased engraving and royal blue champlevé enamel. Each link of the bracelet is hinged for comfortable wear, but the appearance is that of a solid bangle. The arched links are superbly engraved in a floral/foliate pattern that appears to be either mistletoe or myrtle. In the Victorian flower language, mistletoe would have been used to convey the meaning “I surmount all obstacles in the pursuit of love” and myrtle, “Good luck in marriage”. The arched links are finished with enameled borders in a Greek key design. The vertical hinge bars a enhanced with enamel in a checkerboard pattern. The design is so detailed that even the tongue of the concealed clasp, invisible when being worn, is fully engraved. Stamped with a French 18K mark.

A chunky French tank bracelet worked in rose and yellow gold. The 1937 World’s Fair gave rise to a fashion for “tank jewelry,” so called for its perceived resemblance to the treads of armored tanks. This bracelet features angular ridges alternating with rounded elements that creates a woven visual effect. The angular segments are reeded, and the center reed of each is stippled for textural interest and is worked in bright yellow gold to contrast with the rose tint of the rest of the bracelet. The tongue of the clasp is marked with French 18K marks and an unidentified master goldsmith’s mark.

A phenomenal and extremely rare George III sterling silver footed wine bottle or decanter coaster retaining its original ruby glass liner. Bottle or decanter coasters of the period are typically formed as simple round collars over turned wooden bases, perhaps enhanced with a bit of engraving or a border. This example is much finer than most others, with its ornately hand-sawn pierced gallery and undulating rim, the whole raised on tall volute feet with scrolled terminals and acanthus leaf capitals. Laurel wreath swags complete the design. The stand is finished with a blown ruby glass liner, precisely cut to fit the silver (it aligns with the silver only if placed exactly correctly). The pierced gallery has a small reserve that appears never to have been engraved. The silver is fully hallmarked for London, 1774-75. As was the practice, the hallmarks were applied before the decoration was complete, and when the piercing was performed, the maker's mark and duty mark were obliterated. Only the edges of those two punches are visible amongst the piercing.

Origin: England, 1774-75. Condition: excellent, all original, no repairs, a few tiny fleabites on the rim of the glass liner. Size: 5-3/8" diameter; 4-1/2" high. Silver Weight: 322.0 grams.

    A fabulous 14K yellow gold and platinum brooch by William Ruser commissioned to celebrate the astounding victory of the Pittsburgh Pirates over the New York Yankees in the 1960 World Series. The brooch is designed as one of Ruser's classic waif-like children, this time dressed in a pirate's costume. One eye is set with a blue sapphire and the other is covered with a platinum eyepatch highlighted with matte black enamel. A platinum earring dangles from one ear. In one hand he holds a baseball bat and in the other a World Series crown set with sapphires and a ruby. The pirate appears to be walking across a bouquet of flowers made of natural freshwater pearls. Each flower is centered with a prong-set brilliant round-cut diamond. Small gold flowers centered blue sapphires complete the bouquet. The back is engraved "Pittsburgh Pirates World Champions 1960". It is also signed by Ruser and marked appropriately for 14K gold and platinum.

    Ruser was famed for his jewels featuring dogs, cherubs and children. He was favored by major Hollywood stars such as Joan Crawford and Loretta Young. He also accepted unusual commission opportunities that allowed for creative use of his favorite design elements. This is one of the wittiest examples of Ruser's work we've seen. He used only the finest raw materials and the design is masterful. Along with a tie bar he designed for one of the stars of the Indy 500, this brooch is probably the finest example of Ruser's sports-related commissions.

    A stunning bombe-form ring, worked in 18K yellow gold and platinum. The center of the ring is set with 63 square cut blue sapphires invisibly-set into platinum, flanked on either side by a total of 62 round brilliant cut diamonds pave-set in gold. Mystery-setting, accomplished by cutting a thin groove into the girdle of each stone and then sliding it along a complex network of fine platinum wires, was invented jointly by Van Cleef & Arpels and Cartier in the 1930s. Today, it remains one of the most technically difficult stone-setting techniques and is tackled by very few houses. The platinum and gold components were fashioned separately and then assembled with a screw mechanism after the sapphires and diamonds were set. The design of the mounting itself locks the stones in place. The sapphires are well-matched and are color-graded as dark, strong blue (B7/5) and overall clarity-graded as eye-clean. The diamonds are of similarly high quality, with H color and VS2 to SI1 clarity. The interior of the shank has a worn maker’s mark. Tested and guaranteed 18K gold and platinum.

    A superb modernist bracelet in 18K yellow gold set with multi-colored gemstones by Bruno Guidi. Guidi was the lead designer and chief goldsmith the the acclaimed Brazilian jeweler Haroldo Burle Marx for more than 30 years. Each piece was created entirely by hand starting from a piece of gold, without the aid of any molds or pre-made elements. In this bracelet, each of the ten links features a colorful cabochon gemstone native to Brazil—amethyst; citrine; moonstone; and blue, pink and green tourmaline. The links are individually hinged so the bracelet is flexible and comfortable. The clasp is stamped "Brazil 18J Bruno Guidi."

    After Burle Marx's death in 1972, Bruno Guidi and his brother Flavio continued working for a few years, making many of the designs they had originally created for Burle Marx.

    A magnificent vintage platinum brooch formed as a floral bouquet featuring three primary blossoms tied at the bottom with a ribbon, and set with a mix of old single cut, old Swiss cut, old European cut, old mine cut, early modern brilliant round cut and French cut diamonds and round brilliant cut sapphires. The center flower features a .83-carat, old mine cut diamond of fancy cognac color and SI2 clarity; surrounded by sapphires. A flower bud is represented just above by a prong-set .34-carat old European cut diamond of fancy light cognac color and VS2 clarity. Leaves are bead-set with mixed cut white diamonds, all in the E-G color range with VS1 to SI2 clarity. Berries are represented by collet-set blue sapphires. The sapphires display P2B zone 30 color (moderate purplish blue) on the Gem Dialogue scale and have VS clarity. The hinged double pinstem is worked in 14K white gold, but the body of the brooch is tested and guaranteed platinum.

    The range of different diamond cuts in this brooch clearly indicates it was specially made to order for a customer using the diamonds already in her possession. Such commissioned pieces are often not fully hallmarked, hence the lack of a mark for platinum or a maker's mark. The quality of workmanship is superb.

    The brooch is accompanied by a June 2008 written appraisal (GIA & NAJA) conforming to the above description and assigning a replacement value of $16,500.

    An imposing Victorian butterfly brooch of exceptional quality and grand dimensions, the fore- and hindwings studded with rose cut diamonds set in silver-topped 18K gold and bordered with oval cabochon rubies set in gold. The thorax is formed of a round opal and the abdomen is a large squarish cabochon pink tourmaline. The design is completed with diamond antennae and emerald eyes. The opal has excellent fire with a good deal of orange and green in the flashes of light. The rubies outlining the wings have medium-light color and are well-matched to the large tourmaline forming the butterfly’s abdomen. The back of the brooch shows masterful à jour work with well-finished piercing to allow light through the stones. The back also retains the original gold pinstem and c-clasp that can be removed with a gold screw assembly. The brooch most likely originally had a comb attachment so the butterfly could be worn in the hair. The brooch is stamped with French gold hallmarks.

    Origin: France, ca. 1875. Condition: excellent. Dimensions: 2” x 2-7/8”. Weight: 27.2 gr. Approximate Total Gemstone Weight (by estimation and formula): diamond, 2.39 cts; ruby, 14.26 cts; tourmaline, 6.87 cts; opal, .97 cts.

    A stunning pair of lage Georgian or early Victorian transitional earrings worked in 18K gold and silver. The earrings, each in form of a convolvulus (morning glory) blossom feature a variety of antique cut diamonds, mostly cushion and mine cuts. The smallest stones are rose cuts. The diamonds are of excellent quality, mostly eye clean and with superb, warm sparkle as the earrings dangle freely. The expert craftsmanship that allowed the diamonds to be set very close together with little metal showing gives the earrings a dramatic appearance when being worn. Most of the diamonds are set “a jour” (open to the light at the back), but the largest center diamonds in the rosettes at the top of each earring are set in cut-down mountings which suggests the earrings were made in the transitional period between the Georgian and Victorian eras. The backs of the rosettes have a layer of 18K gold so the silver wouldn't tarnish the wearer's earlobes. The wires are 18K gold and are probably replacements of the originals.
