This stunning sterling silver art deco ring features a triangular black onyx stone decorated with marcasite.
Black onyx is a member of the chalcedony family and has been used in jewellery for centuries, most notably in ancient cameo jewellery.
Once used as a substitute for the shine of a diamond, the natural semi-precious gemstone marcasite is now celebrated for its lustre and metallic beauty.
