- Brookite, Quartz
- Union Carbide Christy Vanadium Mine, Magnet Cove, Hot Spring Co., Arkansas, USA
- Thumbnail, 1.5 x 1.0 x 0.9 cm
A rare and fine brookite thumbnail from the Christy Mine at Magnet Cove, Arkansas. A sharp, lustrous, 1.0 cm, complete all-around and pristine, brookite crystal is set atop included quartz on this aesthetic specimen. The sharp, little, terminated quartz crystal at the base of the piece and the tinier quartzes set on the brookite are very nice accents. Ex. Dick Jones Collection.
