Individual listing http://www.etsy.com/listing/54621806/ladies-black-diamond-sterling-silver A black diamond is a genuine diamond that has been enhanced through a radiation treatment to obtain a uniform black color. Just like white diamonds, black diamonds are a 10 on the Moh's hardness scale and make a good stone for everyday wear. The dinosaur bone used in these rings is usually referred to as “gem bone”. It is actually not bone but is a combination of minerals that replaced the bone over time. Dinosaur bone is found in a rainbow of colors with the webbing color and cell size varying greatly from piece to piece. The varying cell size and colors create some truly unique patterns and virtually one of a kind pieces of jewelry. The fossilized dinosaur bone can be composed of many different minerals including agate, jasper and calcite. The dinosaur bone color is determined by the combination of minerals present when the fossilized bone formed.
