A Tanzanite MATRIX phenomenon!
This piece was originally quite dark, and is the exception to the other pieces on this website. It has been gently heated in a gem-oven, to bring out the brightness and colour of the Tanzanite!
Although the specimen no longer hosts the small Pyrite or Calcite that were on the matrix prior to heating, it now has an incredible bright, gemmy blue Tanzanite to show off!
Largest Crystal: 5 x 1.5 x 0.85cm
