2.1" Anatase Crystals on Matrix - Pakistan
This incredible specimen contains 7 easily visible, metallic anatase crystals, associated with small quartz crystals, on a rough matrix. The largest anatase crystal on this specimen measures in at .46" long, though it's size can be overlooked when compared to the variety of other anatase crystal sizes and terminations covering the matrix. Clusters of anatase crystals can also be found throughout the specimen, leaving some anatase crystals with unique formations.
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.
