An extraordinary modernist fringe necklace in 18K yellow gold and green tourmaline by the famed Brazilian modernist jeweler Haroldo Burle Marx. Burle Marx invented the technique of carving and tumbling forma livre ("free form") gemstones in 1948, and the technique became his signature. Most often, he used colorful stones native to Brazil—tourmalines, amethysts, aquamarines, citrines, etc. The tourmalines in this necklace are of the finest quality, with pure deep green coloring that contrasts beautifully with the gold mounting. Burle Marx never used pre-cast elements in his jewelry, and each piece was completely raised by hand from a gold ingot. All the plain gold links are accented with a brushed texture, and the links set with tourmalines have a contrasting florentined finish. The back of the clasp is stamped with Burle Marx's signature and 18K marks.

Burle 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 state gifts for the empresses of Japan and Iran, the queen of Denmark, and the prime minister of India, among others. In Hollywood circles, he was a favored jeweler to Natalie Wood and Mergle Oberon.
