Image 26 of 50
This is an interesting and unique example of Laurellite. (A cuprian tourmaline with a reverse Alexandrite color change.) Only the violetish side of the stone changes color. One end of the bi color is relatively pure while the other end has many fine inclusions. It is still a pretty stone irregardless of its cuprian nature. It weighs 1.16 carats.
