A species of Minerals, Also known as Wiserine, Hydrotitanite, Oisanite, Schorl Octaedre Rectanglaire, Acide Titanique

Anatase is one of the three polymorphous forms of naturally occurring titanium dioxide. It comes in a wide range of beautiful colors, from amber yellow to pale blue-green. Although these crystals are exceptionally beautiful, they are usually much too small to be cut. Faceted gems are therefore very rare.
