4.2" Anatase and Chlorite Quartz - Pakistan

 
 
 
 
 
This beautiful specimen contains 3 distinct, flat-end terminated metallic anatase crystals, associated with large mossy green chlorite-dusted quartz crystals. Various sizes of quartz cover the specimen, with the smaller terminated crystals displaying a herkimer diamond-like clarity. The unique mix of clean quartz terminations, chlorite dusting, bed of small albite crystals, and anatase crystals with an exposed cluster, makes this specimen truly wonderful. The largest anatase crystal on this specimen measures in at .32" long.

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.
