This beautiful Tourmaline was mined in the 90's. It is double terminated and shows dynamic crystallization. There's an interpenetrating crystal at the green cap termination. The top of the interpenetrating crystal is multi terminated on top and re-healed on the bottom. The opposite termination shows a degree of geological displacement, where there is an additional termination "layer," that grows on top of the otherwise complete termination. There are gemmy little lepidolite crystals on the surface that makes for a pleasant contrast.  It weighs 76.4 grams! It's in excellent condition with only two TINY chips on the edge of the termination (doesn't interrupt the edgeline) and is very hard to see. Really good color.
