How often do you see large, well defined American columbite crystals?  This piece comes from an obscure Black Hills locality, and is by far one of the better American columbites that I have seen for sale.  The main crystal is perfectly terminated, and spans th elength of the specimen, part of it freestanding.  The specimen stands perfectly for display.

Ex. Chris Korpi collection.
