Solid brass with Bloodstone and 18 carat gold plating Diameter    12mm  These discreet cufflinks are set with Bloodstone, a beautiful dark green chalcedony containing subtle red flecks of iron oxide. The deep forest green colouring of the stone perfectly suits a formal wear setting yet it is an original take on traditional black onyx. The bloodstone is sourced in India in line with the ethical standards of the World Jewellery Confederation.
