Description |
This is Tanzanite that is naturally colored and not heat treated. Virtually all Tanzanite heat treated to produce its fine color; this specimen shows how Tanzanite looks in its natural state, with a grayish-green to brownish tone. There are two different angles shown here in this photo which exhibit its different colors due to this mineral's strong pleochroism. |
