A lovely vintage aquamarine in diamond ring set in 14K white gold. The ring features a fine 21.74-carat oval mixed cut aquamarine flanked by a pair of .136-carat round brilliant cut diamonds. The split shank holds the aquamarine high above the side diamonds in a cage setting. The aquamarine is graded as light, very slightly grayish, slightly greenish-blue (slgB3/3) in color; good cut, and Type I eye-clean clarity. The aquarmarine is quite large, but its light tone and color saturation gives the ring a lighter feel than it might have with a darker stone. The diamonds are both I color and good cut, one with SI1 clarity, and the other with VS2 clarity. The interior of the shank is marked “14K”.

A very attractive 18K yellow gold ring in the Retro Moderne style set with an emerald cut synthetic pink sapphire enclosed at either end with a pair of square cut synthetic rubies and a natural round brilliant cut diamond. The stones are set in an ornate scrolling mount. The colorful design, with its strong contrasts, makes for a very attractive, fun ring. Synthetic rubies and sapphires were frequently used during the Retro period, even by the most exclusive jewelers, because many stones were unavailable to World War II. Tested and guaranteed 18K.

A chunky French tank bracelet worked in rose and yellow gold. The 1937 World’s Fair gave rise to a fashion for “tank jewelry,” so called for its perceived resemblance to the treads of armored tanks. This bracelet features angular ridges alternating with rounded elements that creates a woven visual effect. The angular segments are reeded, and the center reed of each is stippled for textural interest and is worked in bright yellow gold to contrast with the rose tint of the rest of the bracelet. The tongue of the clasp is marked with French 18K marks and an unidentified master goldsmith’s mark.

A superb pair of 18K gold earrings from the Retro period. Each earring is shaped as a pair of golden flowers, the centers collet-set with old European-cut diamonds.

A classic Retro 14K gold, platinum, diamond and ruby mesh buckle ring by Tiffany & Co. The folding buckle is set with four round rubies and a small diamond in platinum. The pointed tail of the ring is set with three additional round rubies. The mesh buckle design was popular for bracelets in Retro jewelry, but rings were far less common. In most cases, rings had a false buckle and could not be opened and closed to adjust the size. This example is functional, and can be adjusted from 5-3/4 to 9-1/2. The inside of the clasp is marked by Tiffany.

A stunning Retro 18K yellow gold strap bracelet of flat hexagonal links in the Van Cleef & Arpels style. The bracelet is engraved at regular intervals with highly-detailed honeybees, their bodies represented by elongated cabochons of hessonite garnet. The use of hessonite garnet instead of the more common similarly-colored gemstones such as citrine is an inspired choice. The interior of hessonite has a wavy, “heatwave” appearance that gives the stone visible texture. It is this texture that so successfully mimics the striations on the body of a honeyee. The engraved legs and wings are beautifully executed. Van Cleef & Arpels created the strap bracelet of interlocking hexagonal plates (the “Ludo Hexagone”) in 1935 and it quickly became a favorite motif of luxury jewelers worldwide. They are occasionally set with gemstones, but this exampled with engraved bees is a first! The clasp is marked with illegible hallmarks. Tested and guaranteed 18K gold.

Origin: Europe, ca. 1940. Condition: excellent. Dimensions: 23/32 in. wide; 7-1/2 in. length. Weight: 61.4 grams. Approximate Total Gemstone Weight: 8.3 cts.

Superb Retro 18K yellow gold and platinum duette brooch set wtih diamonds and rubies. The design is an exciting overlap of scrolled gold ribbons, the ends accented with platinum and pave-set with round-cut diamonds. The center of the brooch is set with a cluster of prong-set round-cut rubies. The back of the brooch features a mechanism that allows the piece two be disassembled into two separate smaller pins. This "duette" mechanism was used only on the finest pieces during the Retro period. Often, the pair of smaller pins would be worn on either lapel, or sometimes just one pin would be used when a more delicate look was needed. The quality of workmanship is excellent. Tested and guaranteed 18K gold.

A fine Retro leaf brooch worked in 14K yellow gold and platinum set with diamonds and sapphires. The curved leaf is lightened by the use of wire construction, a technique often seen in French jewelry of the period. The lower edge of the wire leaf is enhanced with antique cushion and old European cut diamonds, and the upper edge with a row of blue sapphires. Two larger old European diamonds are nestled among the solid leaves to one side. The three largest diamonds range from .55 to .30 carat. All are SI1 clarity I-J color. The sapphires have bright pure blue color and eye-clean clarity. The design is versatile and the pin can be worn horizontally with the wire leaf to the left or vertically with the wire leaf at the bottom.

The use of such a range of antique diamond cuts in a piece of this era suggests that the pin was custom-made using diamonds (and possibly the gold) from one of the client's older jewels. This was a common practice during the shortages of World War II. The pinstem is stamped "14K."

A very good Retro tank ring worked in 14K yellow gold and platinum set with diamonds and natural sapphires (natural sapphires in a Retro ring are rather unusual). The larger diamonds (.40 ct, .25 ct, and .25 ct) are all old European cuts. The smaller stones are single cuts. The ring is broad across the finger and is laid out in a very geometric style typical of tank jewelry. The diamonds I color and VS2 clarity. The sapphires show no indication of heat treatment. It is very uncommon to have natural colored stones in a piece or Retro jewelry. The back of the shank is stamped with French import marks for 14K gold and platinum.
