Onyx

Onyx is a semi-precious stone, a variety of chalcedony, best known in deep black, though classic onyx is banded, with parallel black and white layers (and most 'black onyx' on the market is artificially coloured). Black onyx is valued for its matte or mirror-polished depth, elegance and severity. Historically onyx was used for carving cameos and seals, and was also considered a stone of protection, strength and self-command. In jewellery black onyx sounds dramatic and refined, contrasting beautifully with silver, gold and diamonds; it is popular in men's jewellery too (cufflinks, signet rings). Onyx is a semi-precious stone of deep black colour, in which a severe, elegant darkness combines with an ancient tradition of carving and a symbolism of strength, making it an expressive, dramatic and versatile stone of both women's and men's jewellery.
