Facet Grade Chrome Green Tourmaline w/ Usambara, Kenya

Real deal Untreated Chrome Green Tourmaline from Kenya with Usumbara effect.
This is an all green stone. You wouldn''t know that by looking at the first few photos. It looks both green and reddish purple when backlit in the sunshine. This red purple color is not actually a color present in the stone but rather a trick of the light called Usumbara effect. This phenomenon is extremely rare in nature and is found only in some Chrome Green Tourmaline. This is highly sought after and is extremely valuable as a gemstone.
