A magnificent pair of Retro leaf-shaped earrings and a matching brooch by Cartier. The leaves are worked in 18K yellow gold and are exquisitely detailed with delicate veining against a softly bloomed matte finish. The stems are worked in palladium, a metal from the platinum group that was used during World War II when platinum was banned from use in jewelry. The stems are bead-set with round single- and brilliant-cut diamonds. The diamonds are very good quality, as expected in vintage Cartier. The brooch has a hinged double pinstem and small safety hooks. The earrings retain their original clip backs with the hinged comfort tabs. The brooch is signed "Cartier" and is marked "18K". The earrings are signed "Cartier", are marked "18K" and "Pal" and have the design serial numbers.

Origin: French design (probably retailed in NY), ca. 1940. Condition: excellent, all original, sharp detail. Size: brooch, 1-29/32" x 1-3/4"; earrings, 1-1/16" x 25/32". Weight: brooch, 21.1 grams; earrings, 10.9 grams. Approximate Total Diamond Weight: 1.0 ct.

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.

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 very good Retro tank ring worked in 14K yellow gold and platinum set with diamonds and natural sapphires (natural sapphires in a Retro ring are rather unusual).

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.

Superb Retro 18K yellow gold and platinum duette brooch set wtih diamonds and rubies. The design is an exciting overlap of scrolled gold ribbons, the ends accented with platinum and pave-set with round-cut diamonds. The center of the brooch is set with a cluster of prong-set round-cut rubies. The back of the brooch features a mechanism that allows the piece two be disassembled into two separate smaller pins.

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.

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.
