A rare combination of Chrysocolla Gibbsite and Malachite only found in this Qinglong mine in China.  Beautiful new find of this rare species. 
 
The name of Chrysocolla was first used by Theophrastus in 315 B.C. and comes from the Greek "chrysos", meaning "gold," and "kolla", meaning "glue," in allusion to the name of the material used to solder gold. André-Jean-François-Marie Brochant de Villiers revived the name in 1808.
 
Chrysocolla is a mineral of secondary origin, commonly associated with other secondary copper minerals, it is typically found as glassy botryoidal or rounded masses or bubbly crusts, and as jackstraw mats of tiny acicular crystals or tufts of fibrous crystals.  There are no known crystals of Chrysocolla.  The chrysocolla "crystals" are all pseudomorphs.  Copper-bearing allophane can look similar.
 
Gibbsite is an important ore of aluminum and is one of three minerals that make up the rock Bauxite.
