An elegant 18K yellow gold ring set with a faceted amethyst by famed mid-century Brazilian designer Haroldo Burle Marx. The sculptural quality of the design is highlighted by the contrast of wire-brushed and polished surfaces surrounding the deep violet amethyst. The interior of the shank is fully signed "Burle Marx 18K" and has Brazilian hallmarks.

Burle Marx worked in Brazil, and his only international boutique was at the Watergate Hotel in Washington, DC. The Brazilian government commissioned him to make state gifts for Queen Elizabeth, Empress Nagako of Japan, Empress Farah Diba of Iran, Queen Margarethe of Denmark, Indira Gandhi, and many others. Among Hollywood royalty, he was a favorite of Merle Oberon and Natalie Wood.

Haroldo Burle Marx is well-known for jewels set with stones in "forma livre" (free-form) designs, but occasional pieces turn up with traditionally-cut stones. Some believe these designs were created in partnership with his brother, the noted landscape architect Roberto.

A fine modernist 18K yellow gold ring by Burle Marx set with an intricately carved amethyst 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 faceting, a technique he invented in 1948. The amethyst's deep purple color beautifully contrasts with the gold, which is worked with florentined engraving typical of Marx's pieces. Tested and guaranteed 18K. Marx did not always sign his pieces; this ring was either unsigned or the signature was removed when the ring was resized at the back of the shank.

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 gifts for visiting heads of state and their wives, including Empress Nagako of Japan, Empress Farah Diba of Iran, Queen Margarethe of Denmark and Prime Minister Indira Gandhi of India. He was also a favorite jeweler of Natalie Wood and Merle Oberon. One of his most important commissions was a gem-encrusted cross for Pope John Paul II.

Origin: Brazil, ca. 1965. Condition: excellent, the ring has been sized at the back of the shank. Finger Size: 8. Dimensions: crown, 1" x 9/16"; shank tapers to 3/16" at the back. Weight: 15.3 gr.

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”.

A fabulous pair of mid-century 18K yellow gold and platinum earclips by Cartier set with brilliant round cut diamonds. The gold surfaces are cast in a rough texture that contrasts beautifully with the bright diamonds set in platinum. The diamonds, as expected of Cartier, are extremely fine quality (E color/VVS2 clarity). French jewelry became more flamboyant in the 1960s, as wartime restrictions eased. Most importantly, jewels were designed for the "modern woman" who wanted to transition her look seamlessly from day to evening. When worn, these flame-like earrings cradle the entire earlobe and rise up gently along the back side of the lobe. Each earring bears French hallmarks and is signed "Cartier."

A vintage Cartier “Trinity” pendant worked in 18K yellow, white and rose gold. Unlike the contemporary “Trinity” pendants that are essentially miniaturized versions of Cartier’s “Trinity” or rolling rings, this pendant is fashioned as a large yellow gold disc enhanced with tri-color gold “Trinity” rings. The gold has a soft matte finish. The pendant looks best hanging from a black silk cord, but can also be worn on a silk cord bracelet. Replacing the black silk with a leather cord, the pendant can be worn by a man. The pendant is signed “Cartier” and has the serial number “H14175”, Italian and French hallmarks, and a 1995 copyright.

Origin: France/Italy, ca. 1995. Condition: very good, normal surface wear from contact with a chain. Size: 11/16” diameter. Weight: 7.6 grams.

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.
