An outstanding late Victorian tiger's claw brooch set in 18K yellow gold and accented with blue sapphires. Tiger claws became popular for use in jewelry following Queen Victoria's proclamation as Empress of India. Big-game hunters often brought back souvenirs of their travels and commissioned jewelry for their friends and family. Usually, the claws are set simply in gold or have an ornate Indian-style mounting, but the use of colored gemstones is extremely rare. The sapphires are of the finest quality, vividly saturated, medium tone, pure blue in color and VSI in clarity. The brooch retains its original extended pinstem. The pin could also be worn as a pendant with the addition of a simple folding bail. Tested and guaranteed 18K. Origin: probably American, ca. 1880. Condition: excellent, all original. Size: 1-13/16"� long x 15/16" wide�. Approximate Total Gemstone Weight: 1.83 cts.

A stunning Belle Epoque brooch in the form of a fern worked in silver-topped 18K gold and set with 89 rose cut diamonds. The curving shape and the delicacy of each individual diamond-set leaf gives the piece a lightness that is very attractive for wear with today's clothing styles. The pin could also easily be converted to a pendant by attaching a gold chain at either end. In the 19th language of flowers, fern conveyed the sentiment of "sincerity." The back is stamped with French 18K marks.

A stunning bombe-form ring, worked in 18K yellow gold and platinum. The center of the ring is set with 63 square cut blue sapphires invisibly-set into platinum, flanked on either side by a total of 62 round brilliant cut diamonds pave-set in gold. Mystery-setting, accomplished by cutting a thin groove into the girdle of each stone and then sliding it along a complex network of fine platinum wires, was invented jointly by Van Cleef & Arpels and Cartier in the 1930s. Today, it remains one of the most technically difficult stone-setting techniques and is tackled by very few houses. The platinum and gold components were fashioned separately and then assembled with a screw mechanism after the sapphires and diamonds were set. The design of the mounting itself locks the stones in place. The sapphires are well-matched and are color-graded as dark, strong blue (B7/5) and overall clarity-graded as eye-clean. The diamonds are of similarly high quality, with H color and VS2 to SI1 clarity. The interior of the shank has a worn maker’s mark. Tested and guaranteed 18K gold and platinum.
