Outstanding very large, well-formed, undamaged Tantalite-(Fe) crystal from the classic Alto Do Giz mine in Brazil. Certainly one of the better tantalite specimens I have seen from this famous mine, in excellent condition with perfect orthorhombic form, pleasing density (has been tested via specific gravity and is definitely tantalite, not columbite!). A serious example of this rare tantalum oxide mineral for the serious collector. From the noted collection of physicist and engineer Dr. George Kamin of Arcadia, California. Rare!
