Purple translucent crystals of Amesite to nearly 5mm. Amesite is a phyllosilicate and member of the serpentine group. It is formed in low grade metamorphic environments. These crystals are pseudohexagonal often tapering along the c-axis. They are stunning under the scope. The purple most likely is due to chromium impurity.

This is an antique specimen with an old label from the University of Amsterdam. The old label, unfortunately, names the dark red crystals Sphalerite. It is not Sphalerite, but rather a garnet. The forms and hardness gives this away......always question identification (yes, even mine) everyone makes mistakes. That's what makes this hobby fun. The clear crystals are very nice Anorthite which is associated with green prisms of hornblende.
