Onyx — the banded variety of chalcedony — is one of the most enduring and sophisticated natural gemstones in fine jewelry. Its deep, uniform black provides the ultimate contrast for precious metal settings, creating pieces of striking, graphic elegance. Each piece is handcrafted in 950 silver and 18k gold in our workshop in Córdoba, Argentina.
