Smooth black onyx sit within our square, rose-gold plated sterling silver frame, with an engraved diamond pattern and black-coloured enamel edge to accentuate the beauty of each semi-precious stone. Decorate your sleeve with one of our stones of the world. The colour and natural formation of our gemstones differs from one another due to natural variation, making each piece truly one of a kind.
