Catalog: Estate Jewelry: Gold: Period (148)

A stunning bombe-form ring, worked in 18K yellow gold and platinum. The center of the ring is set with 63 square cut blue sapphires invisibly-set into platinum, flanked on either side by a total of 62 round brilliant cut diamonds pave-set in gold. Mystery-setting, accomplished by cutting a thin groove into the girdle of each stone and then sliding it along a complex network of fine platinum wires, was invented jointly by Van Cleef & Arpels and Cartier in the 1930s. Today, it remains one of the most technically difficult stone-setting techniques and is tackled by very few houses. The platinum and gold components were fashioned separately and then assembled with a screw mechanism after the sapphires and diamonds were set. The design of the mounting itself locks the stones in place. The sapphires are well-matched and are color-graded as dark, strong blue (B7/5) and overall clarity-graded as eye-clean. The diamonds are of similarly high quality, with H color and VS2 to SI1 clarity. The interior of the shank has a worn maker’s mark. Tested and guaranteed 18K gold and platinum.

A very nice 18K yellow gold ring in the Sputnik style by H Stern. The sphere is bezel-set with round citrines, amethyst, green tourmalines and aquamarines. This design was created in the 1950s to highlight the range of colored gemstones available from the mines of the jeweler’s native Brazil. It later came to be known as “Sputnik” for its resemblance to the spike Soviet satellite launched in 1957. Each ring has a unique appearance stemming from the specific combination of gemstones used. This example has a large number of citrines in a fine, golden honey color. Combined with the green shades of tourmaline, the overall appearance is almost autumnal. The shank is signed by Stern and is marked for 18K gold. This example is on the smaller side and is ideal for wear as a pinky ring or on a smaller hand.

Origin: Brazil, ca. 1955. Condition: excellent, all original. Finger Size: 5-3/4. Dimensions: dome, 5/8” diameter. Weight: 2.8 grams. Approximate Total Gemstone Weight: 1.10 carats.

This design was originally created by H Stern in the 1950s to showcase the range of colored gemstones available from the mines of the company's native Brazil. It later came to be known as "Sputnik" for its resemblance to the spiky Soviet satellite launched in 1957. Each piece has a unique appearance resulting from the specific combination of gemstones used. This pendant has rich look with unusually saturated colors. The Sputnik design was most commonly used for rings; pendants are difficult to find. Tested and guaranteed 18K.

A fine modernist 18K yellow gold ring set with an intricately carved aquamarine in the "forma livre" (free form) style. Haroldo Burle Marx was particularly known for his use of large gemstones, often fashioned by carving or tumbling rather than being faceted, a technique he invented in 1948. The color of this aquamarine is quite nice—almost a Prussian blue. The gold mounting is decorated with the fine florentined engraving often seen on Marx pieces. Some of Marx's rings are quite bulky, but the narrowness of this ring truly flatters the hand. The ring is an iconic piece and would be immediately recognizable by any Burle Marx collector. The interior of the shank is signed “Burle Marx” and is stamped “750” and “Ind. Bras”.

Marx worked in his native Brazil, but his only boutique was located at the Watergate Hotel in Washington, DC. He was chosen by the Brazilian government to create gifts for visiting heads of state and their wives including Empress Nagako of Japan, Empress Farah Diba of Iran, Queen Margarethe of Denmark and Indian Prime Minister Indira Gandhi. He was also a favored jeweler to Natalie Wood and Merle Oberon. On of his most important commissions was a gem-encrusted cross made for Pope John Paul II.

Origin: Brazil, ca. 1965. Condition: excellent, all original. Finger Size: 5-3/4”. Dimensions: crown, 1-1/16”; shank tapers to 5/32” at the back. Weight: 10.8 grams.

A rare pair of 18K yellow gold earclips in the Sputnik style. The spheres are collet-set with round amethysts, citrines, pink and green tourmalines, garnets and aquamarines around central aquamarines set at the tops of the domes. This design was originally created by H Stern in the 1950s to showcase the range of colored gemstones available from the mines of the company’s native Brazil. It later came to be known as “Sputnik” for its resemblance to the spiky Soviet satellite launched in 1957. Each piece has a unique appearance stemming from the specific combination of gemstones used. These earrings have a bright appearance with strong aquamarines and light pink tourmalines. The earrings retain their original clips which could easily be replaced with posts, if desired. The earrings are unsigned, but most likely by Stern. Tested and guaranteed 18K.

A stunning pair of vintage 18K yellow gold and platinum earclips set with diamonds by Cartier. The clips are worked in heavily textured gold that resembles a flame motif that ascends the earlobe when being worn. The recessed parts of the texture are unpolished, creating a strong contrast with the remaining highly-polished surfaces. Each clip features a irregularly shaped cluster of nine platinum-set round brilliant diamonds, graded as E-VVS2. These earrings are a lovely example of Cartier's prevailing style in the early 1960s. The gold shortages that followed World War II were in the past, so jewelry could take on a heavier look; and there was a pronounced fondness for chunkier, daytime jewelry that reflected the modern woman. It was important, however, that the jewelry could be worn in the evening as well. The backs are signed "Cartier France" and bear all the appropriate marks for 18K gold. The clips are original and never had posts, but posts could be added without disturbing any of the signatures or markings.

Origin: France, ca. 1962. Condition: excellent. Size: 5/8" x 1-1/4". Weight: 12.3 grams. Approximate Total Diamond Weight: 1.0 carat.

This delicate 14K yellow gold ring is set with a beautiful fire opal surrounded at compass points by old European cut diamonds. Fire opal is an uncommon stone, and it is very rare to find with play-of-color, the flash effect seen in traditional opals. This stone flashes with red, green and blue. The strong orange body color and fine clarity makes this a beautiful stone. The diamonds are quite good quality and are particularly bright against the orange fire opal. The shank is finished with milligrained edges on both sides. It is engraved “My love, forever 6-16-56”. It is stamped 14K and has an unknown maker’s mark.

Origin: America, 1956. Condition: excellent. Finger Size: 6. Crown Size: 7/16” x 7/16”. Weight: 2.1 grams. Approximate Total Gemstone Weight: fire opal, .71 ct; diamond, .12 ct.

A fine and large pair of 18K yellow gold and multi-stone Sputnik earrings by H Stern. This classic modernist design features goldn domes studded with various colored gemstones including green tourmaline, pink tourmaline, amethyst, aquamarine, citrine and garnet. Each piece of Sputnik jewelry has a unique appearance depending upon the combination and arrangement of the gemstones. The design was created specifically to show off the range of colored gemstones from Stern’s Brazil mines, but it quickly came to be known as “Sputnik” because of its spiky resemblance to the 1960’s Soviet satellite. The clips are marked with an older Stern hallmark. The earrings have their original clips and never had posts. Posts could easily be added. Marked “750” and “18K”.

Each of the spheres is completed with the addition of prong-set seed pearls. The spheres dangle freely and exhibit lots of movement.
