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 larger diamonds (.40 ct, .25 ct, and .25 ct) are all old European cuts. The smaller stones are single cuts. 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 lovely 18K yellow gold, diamond and ruby love pendant (“medaille d’amour”) with a rebus spelling out “Plus qu’hier, moins que demain” (“More than yesterday less than tomorrow”), a line from a love poem written by Rosemonde Gérard to her husband Edmond Rostand (author of “Cyrano de Bergerac”) in 1889. The word “plus” is symbolized by a plus sign set with rose cut diamond and the word “moins” is symbolized by a minus sign set with rectangular synthetic rubies.

In 1907, the Lyonnais jeweler Alphonse Augis created a love token based on the poem. This example, signed by Augis, is the classic version with the crepe de chine textured background enclosed in a plain border. The use of a rose cut diamond and the Augis signature indicates that this is an earlier example. The size is perfect as a pendant on a delicate chain or as a charm on a bracelet. Fully marked with 18K gold marks, and Augis’ maker’s mark.

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."

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. This "duette" mechanism was used only on the finest pieces during the Retro period.

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.
