Anatase

Before the official adoption of the name "anatase," gems such as this were called oisanites, after the type locality, St Christophe-en-Oisans, Bourg d'Oisans, Isère, Rhône-Alpes, France. This beautiful topotype on matrix comes from the same deposit. Photo by Didier Descouens. Licensed under CC By-SA 4.0.
