Details: Museum quality purple / blue tetrahedral fluorite crystals on a white quartz matrix.
The contrast of the matrix with a nearly perfect flush of crystals across the entire
specimen provides an incredible esthic quality. The specimen is also thin enough
to transmit light from back to front. Several generations of fluorite and quartz
appear to have intergrown. A specimen of this quality and size, so free of damage, is rare.
Locality: Shangxii, China.
Size: 24.8" by 21.7" x 3", Weight: 63.8 lbs.
