This is a very rare double terminated  "Schorl "crystal. It is a natural crystal not altered in any way. Shaped by mother nature. It would add to any high end collection. Or for medaphisical purposes. This is a total power crystal, if I ever seen one. I do not know what to say about this excerpt. I am in awe. What a cool specimen. 

It will be in my personal collection until it sells. 

We purchased this in a old collection. I believe it is from China. 

Size: 78 mm. x 72 mm. x 66 mm. 

Weight. 1.5 lb.   Or 680 grams
