Description

Good crystallized tremolite, especially collectible ones, are not very common. Gemmy green ones are almost unheard of. This is a superb green transparent single terminated loose single "chrome-tremolite" crystal, complete all around. It is difficult to tell if the edges of the crystal are slightly chipped or natural; I believe natural. The termination is perfect and the faces are lustrous! This is an outstanding gem crystal for this species!
