A rare pair of large 18K yellow gold Sputnik earrings by H Stern. The domes are bezel-set with round amethysts, citrines, aquamarines, peridot, green tourmalines, pink tourmalines, and garnets.

It later came to be called "Sputnik" for its resemblance to the spiky Soviet satellite launched in 1957. Each piece has a unique appearance depending on the specific colors of the stones and their arrangement. These earrings are of a particularly large size. The earrings currently have posts, but those could be removed if desired. Marked for 18K.

A wonderful Imperial Russian witch's heart brooch and pendant worked in silver-topped 14K gold and set with 78 rose cut diamonds and a heart-shaped garnet. Interestingly, the garnet is not cut in a standard heart shape, but in a slightly curved fashion that echoes the overall shape of the pin. The heart is topped with a ribbon motif. In Victorian jewelry symbolism, the witch's heart conveyed the meaning, "Bewitched by love." The brooch is Russian, but the pinstem and clasp were replaced around 1920, and at that time the brooch was then marked with a transitional Polish hallmark used 1920-21 to remark items that had been created during the time Poland was occupied by Imperial Russia. The brooch also retains the original Russian maker's mark "KK".

A gorgeous and generously sized Art Nouveau 14K gold and diamond locket by Carter, Gough & Co. The cover features a maiden emerging from a bouquet of flowers. The choice of flowers in the bouquet sends a very specific hidden meaning in Victorian floral symbolism. The iris on the left means, "I have a message for you," and the jonquil on the right means, "I desire a return of affection." The flowers and the maiden's hair are studded with six old mine cut diamonds. The background is worked in a stippled pattern that contrasts beautifully with the hand-chased design. The back of the locket has a period three-letter monogram "MCR". The interior retains the original frame and is engraved "June 30, 1903." The interior is stamped with Carter, Gough's hallmark.

A very fine dress set, comprising a pair of barbell cufflinks and four shirt studs fashioned from large South Sea black pearls set in 18K yellow gold. The pearls in the cufflinks are approximate 12.9mm and those in the studs are approximately 10.6mm. The pearls, with good luster and surface condition, are graded as AA quality. The body color of the cufflink pearls are grayish-silver with rose overtones and the stud pearls are blackish-silver with rose and green overtones. Lighter pearls are not often used for men’s jewelry, but the rich coloring and subtle overtones of these pearls creates a very masculine appeal. Louis Tamis & Sons opened his studio in 1909 and quickly became the leading American maker of gold boxes and other objects. In the 1930s, he manufactured for Paul Flato. Since the middle of the century, the company has become one of New York’s most exclusive manufacturing jewelers—creating commissioned pieces for Tiffany & Co., Cartier and Van Cleef & Arpels, as well as a small collection of jewelry under its own name. Each of the cufflinks and studs is marked “18K” and has Tamis’ hallmark.

This exceptional verre eglomise rock crystal panel depicts a maiden in classical dress playing with a hound. She sits on a plinth in a clearing with cypress trees in the background. The scene is backed with grayish mother-of-pearl that seems to create a sky of swirling clouds. The reverse of the pendant is simply finished with pale grayish-blue silk. The plaque is simply mounted in an 18K yellow gold frame with a bail at the top. Verre eglomise was most often used in mourning jewelry, but nothing about the composition of this scene suggests it was created for memorial purposes. In fact, the unusually playful interaction of the dog and the maiden, the latter with a delicately painted smiling face, suggests just the opposite. The pendant was found in France, but the absence of a hallmark suggests England as a more likely place of origin. Tested and guaranteed 18K gold.

Origin: England or France, ca. 1800. Condition: excellent, a 1/8" flake on one edge of the front crystal and a couple of 1/8" faded areas to black border, all visible only with strong, raking light. Size: 1-3/8" x 1-3/4" (excluding bail).

A fascinating 18K yellow gold cocktail ring featuring a "forma livre" (free-form) amethyst by the famed mid-century Brazilian designer Haroldo Burle Marx. Burle Marx invented the technique of carving and tumbling forma livre stones in 1948, and the style became his signature. The amethyst chosen for this ring has distinct color zoning that creates an interesting interplay of deep and light purple coloring. The setting is finished in the florentine style typical of Burle Marx's work. The interior is stamped "750" for 18K. The ring is unsigned, but is definitely by Burle Marx.

Burle Marx worked in his native Brazil, and his only international boutique was at the Watergate Hotel in Washington, DC. He was chosen by the Brazilian government to create state gifts for Empress Nagako of Japan, Empress Farah Diba of Iran, Queen Margarethe of Denmark, and Prime Minister Indira Gandhi of Indian. In Hollywood circles, he was a favored jeweler of Merle Oberon and Natalie Wood.

A superb pair of Victorian drop earrings featuring old European cut diamonds in buttercup settings surrounding oval mixed-cut rubies. The diamonds are separated with radiating lines of black taille d'epargne enamel. The rubies have a classic slightly purplish-red color with good intensity and eye-clean clarity. All rubies fluouresce in natural sunlight to some degree, and these rubies have a particularly strong reaction in bright sunlight, turning an intense red. The microscopic inclusions in the rubies indicate that they are unheated, and the probable source is Burma. The diamonds are F/VVS2. Tested and guaranteed 14K.
