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.

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.
