A lovely Chinese carved green jade pendant in the form of a melon with a crane, leaf and integral bail ring. The jade has good translucency, light mottling, and nicely saturated color.

The crane, appearing along the upper left side of the melon's front, frequently represents longevity; the coins prosperity; and the melon itself has a number of meanings including fertility and plenty.

The pendant was originally one of several carvings incorporated into a very good 1920s Chinese necklace. Material of that age pre-dates polymer treatments and gemological testing reveals no indication of color enhancement, thus the jade is Type A.

Origin: China, ca. 1915. Condition: very good, no cracks, a 1/8" loss along the bottom edge of the tendril below the crane (could be repolished). Dimensions: 3/4" x 1-1/2".

NOTE: Other items created from the same antique necklace include Items #1350553, #1350538, and #1350547.

An exceptional and extremely rare 14K yellow gold, amethyst and pearl ring by Edward Everett Oakes. The crown is fashioned as a cluster of oak leaves and acorns surrounding two round amethysts and two half-pearls in collet settings. The amethysts are graded as medium-dark strong purple (P 6/6); with excellent cut and Type I eye-clean clarity. The pearls have nice luster and creamy body color.

Edward Everette Oakes (1891-1960) was perhaps the foremost Arts & Crafts jeweler in America. He was a member (and medallist) of the Boston Arts & Crafts Society, and became the first living artist to have a work acquired for the permanent collection of the Metropolitan Museum of Art. He trained with Frank Gardner Hale and worked for three years with Josephine Hartwell Shaw before opening is own studio in 1917. Oakes' work shows a certain similarity to both Hale and Shaw, but his mature style is noticeably original. Most of his pieces are unsigned, but can be identified based on their unique decorative motifs and construction techniques.

Oakes regularly visited Camp Deephaven and Camp Rockywold on Squam Lake in New Hampshire. The original owner of this ring purchased it directly from Oakes during one of her 68 consecutive annual summer stasys at the camps. The purchaser will be supplied with a copy of a letter from the original owner's niece describing her aunt's purchases.

Origin: America, ca. 1920. Condition: excellent, has been sized. Size: 3/4" wide at crown. Finger Size: 7. Weight: 6.1 gr. Approximate Total Gemstone Weight: 1.88 cts.

A handsome pair of French Art Deco cufflinks, the faces worked in platinum centering sugarloaf cabochons of moonstone surrounded by rose cut diamonds. The moonstones have matte finish more often used with rock crystal, and the underlying, bright, billowy adularescence creates a very attractive effect.

Though there are no maker's marks to substantiate it, the overall quality of design and execution suggests an important maker such as Cartier.

A lovely two-sided 18K gold and crystal photo locket by Parisian jeweler Charles Garnier. This style of locket became popular in the latter half of the 19th century and was revived from time to time up through the Edwardian era.

A lovely 18K yellow gold, diamond and ruby love pendant ("medille d'amour") with a rebus spelling out "Plus qu'hier, moins que demain" ("More than yesterday, less than tomorrow") a line from a love poem written by Rosemonde Gérard to her husband Edmond Rostand (author of "Cyrano de Bergerac") in 1889. The word "plus" is symbolized by a plus sign set with rose cut diamonds and the word "moins" is symbolized by a minus sign set with rectangular cut synthetic rubies.

In 1907, the Lyonnais jewelry Alphonse Augis created a love token based on the poem. This example, signed by Augis, is of better than average quality, with intricate engraving on the background and a lovely engraved floral border. The oval shape is also less common the the usual circle. The use of rose cut diamonds, synthetic rubies and Augis' signature indicates that this is an earlier example. The smaller size is perfect as a pendant on a delicate chain or for wear on a charm bracelet. Fully marked with 18K gold marks, and Augis' maker's mark.

Origin: France, ca. 1925. Condition: excellent. Dimensions: 1/2" x 7/8" (from top of bail).

A fine large-size enameled 14K yellow gold Art Nouveau flower pin the form of a pansy. The petals are beautifully decorated with purple, violet cream and yellow opaque enamels. The enamel has a soft luster that mimics the velvety texture of an actual pansy. The flower is centered with a 15-point round brilliant diamond of exceptionally good quality (E color, VVS2 clarity). The specific shape and arrangement of the petals identifies this pin as being made by Larter, but the company also supplied these pins to luxury retailers such as Tiffany and Cartier where they were marked with the retailer’s mark. This pin has an unidentified mark (the Greek letter omega) and has faintly inscribed inventory numbers often found on pieces that were sold by luxury jewelers.

An exceptional pair of Art Deco platinum, emerald, diamond and onyx cufflinks by Cartier. Each face is made from a melon-carved emerald bead dating to India's Mughal Empire (17th/18th centuries), topped with a round onyx disk centered with an old European cut diamond. The emeralds, variously weighing approximately 5.94, 5.49, 4.53 and 4.20 carats, totalling just over 20 carats. The emeralds have a strong green color with natural inclusions characteristic of the Chivor mines in Colombia. The diamonds are graded as F color, VVS clarity. The faces are joined with removable dog clip connectors. The fixed mountings are marked with the workshop master's mark used in the 1920s and French platinum marks and are signed “Cartier.” The cufflinks are presented in their original fitted, silk- and velvet-lined, fitted leather case.

Jacques Cartier was one of the first European jewelers to travel to India and to acquire antique emerald, ruby and sapphire beads from the maharajahs. These stones were re-set in Cartier's Paris workrooms. One of the most important commissions using carved Mughal beads was a brooch for Marjorie Merriweather Post. That brooch features emeralds carved in the same shape as those in these cufflinks.

A stunning Art Deco gentleman’s dress set comprising a pair of double-faced platinum cufflinks and three shirt studs. The round platinum faces are enhanced with ridged decoration and feature round old European-cut diamonds. The faces are attached with removable connectors for ease in putting them through cuff holes. The backs are marked with Swiss platinum hallmarks and Imperial Austrian import marks. Both marks are no longer in use, and by cross-referencing the marks, we can determine that the cufflinks date to 1914-21.

The set is completed with a vintage set of matching shirt studs commissioned from Gübelin, one of the world’s most exclusive jewelers, in the 1950s. Working only in Switzerland, Gübelin is known especially for its peerless selection of gemstones and for the workmanship of its Swiss master jewelers. The studs match the cufflinks perfectly, and each is stamped with Gübelin’s hallmark and the custom order number. The toggle backs are 18K white gold, and the faces are hallmarked for platinum. The studs are presented in their original fitted suede-covered Gübelin case, which also has enough room for the cufflinks.

Gübelin did not have its own jewelry manufacturing facilities until the late 1920s, and given the perfect match between the cufflinks and the studs, it seems likely that the cufflinks, themselves, were probably originally retailed by Gübelin.

Origin: Switzerland. Size: cufflinks, 1/2" diameter; studs, 13/32” diameter. Weight: 13.5 grams. Approximate Total Diamond Weight: .95 carat.

A phenomenal Edwardian platinum, diamond and amethyst bow brooch by Cartier. Four tromp l'oeil amethyst loops, each surrounded in old European cut diamonds, flank a center 1.08 carat, J/K, VS2 old European cut diamond.

Each of the double loops of the bow appears to be set with two amethysts, but there is in fact only one amethyst on each side. The gemstones are precision-cut to fit perfectly into the platinum setting and give the appearance of being four stones. The amethysts are graded as medium, moderately strong Purple (P5/4) in color, with eye-clean clarity. This is the color and intensity sometimes termed "Siberian".

The 104 old mine cut and rose cut diamonds along the platinum borders total approximately 2.94 carats range from VS2 to SI2 clarity and H-J color.

The platinum setting is beautifully crafted, with a pierced gallery and engraved details around the collet setting of the center stone.

The brooch is hallmarked with the extremely rare master goldsmith's mark used by Cartier for only a three-year period, 1919-1922.

Origin: Paris, France, 1919-1922.

Unlike some of the other opal patterns, pinfire has the distinction of showing pattern when viewed from any direction. Even the bottom of the stone visible through the mounting has nice color and pattern. The colors of the stone are nicely accented with the enamels on the mounting. The shank is engraved in a floral pattern and is accented at the shoulders with floral appliques worked in white gold. The interior of the shank is marked "14K" and has an unidentified maker's mark.
