Turquoise ps. Apatite (large crystal)

Item Description

A single light turquoise colored crystal composed of rough prism faces and crude pyramidal faces with the form of an Apatite crystal, because that previous species has now been replaced by Turquoise. This Mexican locality is known for these pseudomorphs where all of the Apatite in the deposit has been completely replaced by Turquoise form later invading copper-bearing solutions. Very cool pseudomorph! Old material, now quite uncommon on the market. They turn up rarely in old collections. This would be considered a rather sharp and fine example. valued over $1000
