A wonderful and very rare pair of signed Eva Segoura ladybug earrings worked in 18K yellow gold, and set with hematite and rubies. Segoura was a very exclusive Parisian jewelry designer at 20 rue du Faubourg St-Honoré for a short time. Many of her jewels were rather whimsical and featured animals such as ladybugs, caterpillars, mice and blowfish. Segoura made ladybug earrings in several variations using different precious and semi-precious stones. These ladybug earrings have bodies of carved hematite set in gold frames. The sides of each ladybug are adorned with collet-set cabochon rubies, as are the eyes. The little creatures are completed with alert antennae and ball feet. The clips are marked with the maker’s mark, the French 18K guarantee mark, and a partially obscured serial number. The backs of the frames are signed “Eva Segoura” in script.

An exquisite and very fine 18K yellow gold jewel by Henry Dunay, one of the greatest American jewelers of the latter 20th century. The piece comprises a 32" necklace of domed, oval gold links joined by polished arched connectors. The outer surfaces of the links are stippled in a roughly textured finish that contrast nicely with the arched connectors. Two of the links have hidden hinged clasps so that the necklace can be separated into a shorter necklace and a bracelet. Two of the arched connectors are joined together at the midpoint to suspend a detachable pendant inspired by ancient Mayan motifs. The pendant is quite large, but the openwork and geometric approach to the design maintain a sense of lightness. The pendant can also be worn as a brooch. All pieces are signed by Dunay and are marked 18K.

The piece is accompanied by a written appraisal (GIA & NAJA) indicating a total replacement value of $34,000. Mr. Dunay, himself, indicated that he recalled making the piece in 1968 or 1969. At that time he did not systematically document his creations, so the jewel has not appeared in published works. He suggested he would charge $34,000 to recreate the piece today.

A stunning Tiffany & Co. ring by Jean Schlumberger, one of the great jewelry designers of the 20th century. He was Tiffany’s lead designer in the 1960s and was charged with creating nearly all of the company’s most exclusive pieces. His designs typically relied on naturalistic motifs. Here, two leaves are worked in platinum and studded with round brilliant-cut diamonds. The stems of the leaves are worked in 18K yellow gold and meld into the double shank that continues the organic motif. The diamonds are of very fine quality, VS clarity, G color. Schlumberger created several pieces using this motif, including the “Three Leaves Earrings” (currently available from Tiffany at $13,500), the “Five Leaves Brooch” ($16,500), the “Three Leaves Sapphire Earclips” ($62,000).
