2.3" Anatase Crystal on Matrix - Pakistan

This specimen contains a metallic anatase crystal, associated with small quartz crystals terminations, on a rough matrix. While the anatase crystals is located on what could be considered the front of the specimen, that back side displays nearly a dozen chlorine coated quartz crystals protrusions.

Anatase is composed of titanium dioxide, and 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, with most crystals ending in points, or with variations of flattening on each end.
