A phenomenal Edwardian platinum, diamond and amethyst bow brooch by Cartier. Four tromp l'oeil amethyst loops, each surrounded in old European cut diamonds, flank a center 1.08 carat, J/K, VS2 old European cut diamond.

Each of the double loops of the bow appears to be set with two amethysts, but there is in fact only one amethyst on each side. The gemstones are precision-cut to fit perfectly into the platinum setting and give the appearance of being four stones. The amethysts are graded as medium, moderately strong Purple (P5/4) in color, with eye-clean clarity. This is the color and intensity sometimes termed "Siberian".

The 104 old mine cut and rose cut diamonds along the platinum borders total approximately 2.94 carats range from VS2 to SI2 clarity and H-J color.

The platinum setting is beautifully crafted, with a pierced gallery and engraved details around the collet setting of the center stone.

The brooch is hallmarked with the extremely rare master goldsmith's mark used by Cartier for only a three-year period, 1919-1922.

Origin: Paris, France, 1919-1922. Condition: very good, there is a small chip on the inside edge of each amethyst near the junction with the center diamond, visible upon very close inspection in strong raking light (one visible only from the reverse). Size: 3" x 27/32". Weight: 18.7 grams. Approximate Total Gemstone Weight: amethyst, 22.68 carats; diamond, 4.02 carats.

Extraordinary pair of early Cartier cufflinks, the round faces featuring brilliant green guilloche enamel in a starburst pattern, bordered with rose-cut diamonds set in delicate double-milgrained platinum borders. The enamel plaques are engraved in a manner that gives the enamel a distinct two-toned appearance and are set into 18K yellow gold backs that are attached to one another with gold chain links. The chains have a spring ring clasp, so one face can be removed for ease in attaching the cufflinks to a shirt. The backs are signed "Cartier Paris" and have serial numbers. The cufflinks are appropriately marked with "tete d'aigle" hallmarks for 18K gold (the cufflinks predate the law requiring marks for platinum). Enameled Cartier cufflinks of this quality simply do not appear on the market.

Origin: France, ca. 1900. Condition: excellent, light surface wear to enamel visible under 10x magnification. Weight: 9.9 gr. Approximate Total Diamond Weight: 1.52 cts.

A buff-cut oval amethyst perfectly offsets the superb gold setting in this Edwardian 14K gold gentleman’s ring. The stone sits in a high setting that is intricately engraved with classic motifs such as pendant bellflowers, swags, and fans that bridge the Edwardian period into early Art Deco. The ring is large, but the relatively light color of the amethyst and the use of smooth buff cut instead of full faceting keeps it from being overpowering. A woman could easily wear the ring, as well. The interior of the shank is stamped “14K.”
