Hand-carved pieces of onyx semi-precious stone take the shape of a traditional knot, one of the oldest forms of cufflinks. Onyx is formed by layered deposits of limestone and is said to bring the wearer grounding and protection. Finished in rhodium plated sterling silver. The colour and natural formation of our gemstones differs from one another due to natural variation, making each piece truly one of a kind. The face of each cufflink measures 13mm length x 13mm height x 13mm width.
