Product Description

Sapphirine is an ancient mineral described around 1920, very common in some types of metamorphic rocks. But curiously, very very rarely encountered in the state of crystals well automorphes. The first potables to be collected were found in Madagascar about 25 years ago. The largest crystals discovered were 2.50 to 3 cm, bluish grey but with rounded faces. It is therefore safe to say that this discovery completely redefines this species from the point of view of the collector both by their size and by their crystallization with sharp, well-defined edges. For crystals on matrix like this, they are surrounded by Anorthoclase. It is this mineral that allows Sapphirine to develop properly and completely, contrary to the first discovery 25 years ago. The matrix is composed of Biotite and Sillimanite. Here, the Sapphirine crystal is complete, with its visible growth streaks. The edges are perfectly defined and sharp.
