About Anatase
Anatase is a mineral composed of titanium dioxide that typically forms dipyramidal crystals, although variations can occur with mineral clumping. Four-pointed, X-shaped anatase crystals, while rare, have been found and are known as "X-shaped penetration twins". Horizontal striations can be seen across most anatase mineral faces and most crystals end in points, or with variations of flattening on each end. It can be found in a variety of colors, from browns and reds to greens and pinks, and can be colorless in very rare cases. However, it is most commonly black or other very dark colors due to impurities.
