Anatase (Titanium Crystals) With Quartz - Pakistan
This gorgeous specimen features multiple pristine anatase crystals that formed from an albite and quartz crystal encrusted matrix. The entire specimen measures 2.3" wide and has been mounted to an acrylic display base with mineral tack.
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.
