An extraordinarily fine antique 18K yellow gold ring by Tiffany & Co. set with a mixed cushion cut Burmese blue sapphire surrounded by old mine cut diamonds. All the gems are of the finest quality. The sapphire has been certified by the American Gemological Laboratories (see the following paragraph). The diamonds, ranging in size from approximately .22 carat to .29 carat each, are estimated at G/H color and SI to VVS2 clarity. The sapphire is set in a prong setting, while the diamonds are set in a shared-prong setting that creates a filigree appearance around the back of the crown. The shoulders of the shank are lightly decorated with beaded engraving.

Nearly all sapphires marketed in the last 150 years have been heated to improve the color. This is considered a standard practice. Other treatments, such as filling in fractures, altering the color family, etc., though considered bad practice, are nonetheless quite common. Fine Burmese stones from the Mogok region that have not been treated in any way are exceedingly rare and only show up in upscale jewels from makers such as Tiffany and Cartier. This particular stone, with its bright coloring and beautiful cut, is nothing short of stunning.

The AGL Brief (dated April 2008) indicates that the sapphire is natural; displays specific properties and characteristics associated with stones from Burma; measures 7.39 x 6.69 x 5.82 mm; weighs 2.49 carats; is cut in mixed cushion, has blue color, and shows no heat or additional treatments. The brief further indicates that unheated sapphires are scarce. The original brief will accompany the ring.

A fabulous 14K yellow gold and platinum brooch by William Ruser commissioned to celebrate the astounding victory of the Pittsburgh Pirates over the New York Yankees in the 1960 World Series. The brooch is designed as one of Ruser's classic waif-like children, this time dressed in a pirate's costume. One eye is set with a blue sapphire and the other is covered with a platinum eyepatch highlighted with matte black enamel. A platinum earring dangles from one ear. In one hand he holds a baseball bat and in the other a World Series crown set with sapphires and a ruby. The pirate appears to be walking across a bouquet of flowers made of natural freshwater pearls. Each flower is centered with a prong-set brilliant round-cut diamond. Small gold flowers centered blue sapphires complete the bouquet. The back is engraved "Pittsburgh Pirates World Champions 1960". It is also signed by Ruser and marked appropriately for 14K gold and platinum.

Ruser was famed for his jewels featuring dogs, cherubs and children. He was favored by major Hollywood stars such as Joan Crawford and Loretta Young. He also accepted unusual commission opportunities that allowed for creative use of his favorite design elements. This is one of the wittiest examples of Ruser's work we've seen. He used only the finest raw materials and the design is masterful. Along with a tie bar he designed for one of the stars of the Indy 500, this brooch is probably the finest example of Ruser's sports-related commissions.

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.

A pretty 18Kyellow gold pin in the shape of a salamander from the reign of Emperor Napoleon III. Animal brooches were very popular in the mid-19th century, and reptiles were especially favored.

This example is beautifully engraved with delicate scales, claws, and eyes. The back is set with a line of alternating seed pearls and Persian turquoise cabochons. The head is set with a larger turquoise. The original clasp is marked with the “tête de cheval” hallmark used only outside Paris between 1838 and 1919.

A nice pair of modernist 14K yellow gold and pearl earrings. 5.2-millimeter pearl studs suspend faceted gold bars that, in turn, suspend open-work gold spheres studded with pearls. Each sphere comprises a dozen 4.9 millimeter cultured pearls of very good quality. The body color is cream with rose overtones. The luster is bright and the surfaces are smooth. Each of the spheres is completed with the addition of prong-set seed pearls. The spheres dangle freely and exhibit lots of movement.

The arrangement of the pearls and the underlying gold structure of these earrings is clearly based on atomic-level molecule models. Tested and guaranteed 14K.

A wonderful and extremely rare Victorian 15K rose gold brooch set with Scottish agate. The brooch is in the form of the 19th century Prince of Wales’ crown enclosing the traditional feathers in fleur-de-lys arrangement, over a banner with the legend “Ich Dien”. The feathers are set with jasper and bloodstone. The engraved decoration of the gold is first-rate. The back bears a registry mark, dating the brooch to 1891. In 1891, Queen Victoria’s eldest son, the future Edward VII, celebrated the fiftieth anniversary of his investitute as Prince of Wales. Due to his mother’s longevity, however, Edward was the first Prince of Wales to reach that mark.

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.

Origin: America, ca. 1968. Condition: excellent, all original. Size: full necklace length, 32" bracelet length, 8-1/2"; shortened necklace length, 23-1/2"; pendant/brooch, 2-11/16" diameter. Weight: 249.09 grams/8.009troy ounces.

Exquisite 1950s triple strand pearl bracelet completed with generously diamond-set 14K white gold spacers and matching clasp. The 7mm pearls are of fine quality, with thick nacre and a lovely sheen, and are beautifully matched. The body color is ivory with silvery overtones. The quality is estimated at A1. Three swirled spacers and a matching clasp, each worked in 14K white gold complete the bracelet. Each piece is set with round brilliant-cut diamonds. The stones are of fine quality, estimated at H color and VVS clarity. Unlike most spacers that simply separate the strands, the spacers in this bracelet are constructed in a way that rows of three pearls seem to be set into the spacers themselves—a unique and particularly elegant style. The matching clasp, completely invisible when closed, is one of the best clasp designs we’ve seen in many years. The back of the clasp is marked “14K”.
