Green Elbaite tourmaline with red termination. This is a good tourmaline crystal. It's not great since there is a lot of internal, but natural flaws as can be seen. The termination is fine with a good deep red color and no damage. I priced it low. The previous dealer had it marked at $595.

Tourmaline crystals with cores of Schorl and outer perimeter of pinkish Elbaite.. There is one crystal of Schorl which appear as three crystals grown in parallel. Mineralogically interesting and good study piece for crystal growth habits in a pegmatite.
