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.

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."
