This ring carries black marbling around making itself look quite mystifying. In Chinese, black jadeite are often called as 黑乌鸡 (HeiWuJi) which means 'black chicken'. As funny as it sounds, it is said that black jadeite often brings good luck and wealth to the wearer. This ring has fine texture with no crystal-like structure. The last picture is taken under natural light setting.
