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.
2.3" long, .9" wide, .24" longest crystal
