An exceptionally fine, heavy 18K yellow gold bracelet by Pierre Baltensperger. Each of the plaques represents a different flower, depicted in semi-abstract ways. Among the flowers are daisies, cyclamens, fuschias, morning glories and honeysuckle. Baltensperger was founded in 1878 by Walter Baltensperger, who quickly established the firm’s luxury reputation. His grandson Pierre Baltensperger assumed the lead in 1950. Pierre, born in 1927, became one of Switzerland’s most important sculptors and visual artists, in addition to his work with jewelry. This design, though similar in some respects to Georg Jensen’s work from the 1920s, likely dates to the late 1940s. The clasp is signed “Baltensperger” and has 18K marks and inventory numbers.

Origin: Zurich, Switzerland, ca. 1947. Dimensions: 5/8” x 7-5/8”. Weight: 40.0 gr.

A rare pair of mid-century haute couture cufflinks by Pierre Cardin. Each face comprises a carved jadeite bead simply mounted on a gold post. The backs are slightly arched gold bars. The jadeite beads are carved in a floral pattern and are done so in a way that they are carved completely through from one side to another. It’s likely that the cufflinks were constructed from an antique strand of jadeite beads. The jade has noticeable mottling in natural, strongly saturated shades of dark, medium and light green. The translucency is fair. Magnification and absorption spectra show no signs of dye. The connectors are signed “Pierre Cardin†and are fully hallmarked with French 18K marks. Pierre Cardin designed a very limited line of fine jewels in the 1950s and 60s. They were sold only at the couturier’s main store and are quite difficult to find now. Origin: Paris, ca. 1960. Condition: excellent, all original, no cracks or chips. Size: 1/2†diameter. Weight: 10.4 grams.

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.

Origin: America, ca. 1950. Condition: excellent, all original. Size: 2" x 1-1/4". Weight: 16.3 gr. Approximate Total Gemstone Weight: diamond, 1.84 carats (1.17 carats of fancy colored diamonds); sapphire, 2.1 carats.

A very fine pair of platinum, diamond and aquamarine earrings in a classic Art Deco style. The brilliant round-cut diamonds graduate from .20 ct at the top to .30 ct at the bottom.

The aquamarines are unheated. Each gemstone is set in a fully articulated mounting with a pierced gallery. The earrings have screw posts. Tested and guaranteed platinum.

An elegant pair of 19K yellow gold "Contas de Viana" earclips. The domes are covered with concentric circles of ropetwist appliques in the ancient Etruscan style. The clips are stamped with older Portuguese hallmarks for 19K.

Viana beads were modeled on ancient Etruscan jewels found in archaeological sites in Portugal. The circular patterns of filigree and granulation were thought to resemble the eyes of a partridge, bringing luck and protection. A Portuguese girl received her first bead from her godmother at birth. Whenever the family could afford it, another bead was added to the collection with the goal being to create a complete necklace—a circle of protection and good luck—in time for her marriage.

Origin: Portugal, ca. 1950. Condition: excellent, no dings. Dimensions: 7/8" diameter. Weight: 9.9 grams.

A very handsome Retro bracelet worked in rose and yellow gold links enhanced with engraving in a snakeskin texture. The color contrast is very attractive, and the links are made in such a way that the bracelet drapes very nicely on the wrist. The box clasp is stamped with Italian gold marks of the period and the goldsmith’s registry number 1 TO for Antica Ditta Marchisio (now Mattioli Gioielli). Founded in 1860, the house is the oldest jeweler in Torino, Italy, and was a maker for several luxury jewelry houses including Cartier.

A pair of vintage sterling silver cufflinks by Hermes. The double baton faces are engraved in a tree bark motif and are connected by chains. Each cufflink is signed “Hermes†and bears appropriate French silver marks. They are also stamped with the silversmith’s hallmark. This is an early design that hasn't been in production in 80 years or more.

Origin: France, ca. 1930. Condition: cufflinks, excellent; box, excellent. Dimensions: faces, 13/16†long. Weight: 14.9 gr.

A very good pair of 18K yellow gold cufflinks by Alfred Dunhill. The faces resemble branches of coral. Dunhill produces the vast majority of its cufflinks in sterling silver and the 18K gold versions are very rare. The coral design, in general, is hard to find because it was made for only a short time around 2005. The cufflinks are constructed with the connector set off-center, so the link lies flat against the cuff. The toggle back is Dunhill’s classic small toggle with the company’s insignia. The connectors are fully stamped with English convention hallmarks for 18K and with the maker’s mark for Dunhill.

Origin: England, ca. 2005. Condition: excellent. Size: 1-1/4” x 3/4". Weight: 17.6 grams.

A handsome pair of Victorian 14K yellow gold double-sided cufflinks, the faces set with cabochon agates. The variety of agate is called “landscape agate” because the colors and markings resemble painted landscapes. These particular stones suggest colorful sunsets behind wooded landscapes. The bezel settings are finished with fine millegraining. The connectors are marked 14K and have an unknown American maker’s mark.

Origin: America, ca. 1890. Condition: excellent. Size: 5/8” x 9/16”. Weight: 10.4 grams.

The chain, fashioned as a series of florets, is alternately set with antique cushion cut sapphires and rubies flanked at compass points by natural seed pearls.

A lovely Retro necklace worked in 14K rose and yellow gold and set with moonstones and amethysts. The necklace descends from a rose gold paperclip link chain toward a pair of openwork yellow gold plaques, each set with a round amethyst accented with a rose gold stylized flower, and flanking a central triangular plaque designed in the same manner. A pair of oval cabochon moonstones is set at either side. The central plaque suspends a larger oval moonstone with a nearly invisible setting. The moonstones have very nice bluish adularescence and the amethysts have rich purple color. The interplay of gemstone and gold colors and the unusual design mixing Victorian, Art Nouveau and Retro elements creates a very striking effect. Tested and guaranteed 14K.

A very nice Retro 14K yellow gold statement ring set with an imposing lemon yellow emerald cut citrine flanked by natural ruby cabochons.

A lovely pair of colorful Retro earrings worked in 14K yellow gold.

A fascinating pair of 14K yellow gold cufflinks set with emeralds. This is only the second pair we've seen with this particular type of mechanism. The "wheat-style" chain is inserted through the cuff and then wrapped around the emerald-set head. It works much like the more traditional stirrup-style, but with more flexibility. Each head is set with a pair of rectangular emeralds. As is typical of the Retro period when trade was restricted by World War II, the emeralds are synthetic. The stones have beautiful, deeply-saturated color. Tested and guaranteed 14K.

An interesting late Retro 14K yellow gold bracelet worked as a series of sextupled cable links that are slightly flattened so they splay out sideways to create a wide bracelet with a sort of optical illusion effect. The clasp is decorated so the bracelet appears seamless when being worn. The open link design makes this a perfect bracelet to wear on its own or with chunky, heavy charms. The interior of the clasp is marked “14K.”

The ring is broad across the finger and is laid out in a very geometric style typical of tank jewelry. The diamonds I color and VS2 clarity. The sapphires show no indication of heat treatment. It is very uncommon to have natural colored stones in a piece or Retro jewelry. The back of the shank is stamped with French import marks for 14K gold and platinum.

A fine Retro leaf brooch worked in 14K yellow gold and platinum set with diamonds and sapphires. The curved leaf is lightened by the use of wire construction, a technique often seen in French jewelry of the period. The lower edge of the wire leaf is enhanced with antique cushion and old European cut diamonds, and the upper edge with a row of blue sapphires. Two larger old European diamonds are nestled among the solid leaves to one side. The three largest diamonds range from .55 to .30 carat. All are SI1 clarity I-J color. The sapphires have bright pure blue color and eye-clean clarity. The design is versatile and the pin can be worn horizontally with the wire leaf to the left or vertically with the wire leaf at the bottom.

The use of such a range of antique diamond cuts in a piece of this era suggests that the pin was custom-made using diamonds (and possibly the gold) from one of the client's older jewels. This was a common practice during the shortages of World War II. The pinstem is stamped "14K."

A fine pair of 14K yellow gold cufflinks, the faces shaped as a convex curve of gold flanked on either side by square cut natural rubies. The superbly-matched rubies have excellent color and clarity, with no indications of heat or other treatment. The nature of the microscopic inclusions suggests Burma as the region of origin. We have seen a duplicate pair of these cufflinks, except set with sapphires, that were signed "Cartier NY". Cartier's New York store retailed jewelry made by various manufacturers such as Larter and Krementz. Sometimes they were marked with Cartier's retailer mark and sometimes not. Stamped "14K".

An elegant Retro 14K yellow gold floral brooch, the flower head set with a ring of blue sapphires surrounding a cabochon moonstone. This classic combination of moonstone and sapphire was very popular in Retro jewelry, probably because the color of sapphires brings out the blue undertones of moonstone. The quality of the stones is very fine. The sapphires are a bright cornflower blue, and the moonstone has very good adularescence. The back is marked “14K”.

Origin: America, ca. 1940. Condition: excellent, all original. Size: 2-3/8” x 1-1/8”. Weight: 13.0 grams. Approximate Total Gemstone Weight: moonstone, .88 carat; sapphire, .43 carat.

An elegant 14K rose and yellow gold bow brooch featuring a “knot” invisibly-set calibre-cut green tourmalines. The brooch is also accented with a pair of pearls set in white gold. The tourmalines have very fine bright coloring. The golden bow is worked in both a polished surface and a micro-beaded finish. The latter is a technically difficult texture to achieve and shows the hand of a master jeweler. The back of the pin is marked “RMU” and “585” for 14K gold. The back retains the original trombone clasp.

A Retro 14K yellow gold bracelet comprising hinged links set with amethysts alternating with diamond-set links. The oval mixed-cut amethysts have medium-dark, vivid reddish-purple color and are well-matched. The small old European and brilliant cut round diamonds add a restrained bit of sparkle. The amethysts are set in a way that makes them appear the float in the larger gold links, creating a sense of lightness in the bracelet. The clasp is marked “14K”.
