A stunning Art Deco style ring crafted from sterling silver set with a central round black onyx cabochon stone, surrounded by sparkling marcasite gemstones. This traditionally banded gemstone is a member of the chalcedony family and has been used in jewellery for centuries, most notably black onyx in ancient cameo jewellery.
