Fluorite and Sphalerite - Sold Cave in Rock, Illinois - Kentucky Fluorspar District, Hardin County, Illinois 5.6 x 4.2 x 3.2 cm (2.2 x 1.7 x 1.3 inches) A fluorite cube set on a carpet of small sphalerite crystals. The fluorite is highly transparent, 1.3 cm along its edge, and either light blue or light purple depending upon the light source. It sits among many bright, lustrous sphalerite crystals, all on a massive sphalerite matrix. A pretty specimen as is, but removing some of the sphalerite matrix could convert this to a outstanding miniature. Very minor edge wear on the fluorite does not detract. |

Completely transparent in some spots and opaque in others. Terminations are slightly bruised, but this is excusable given the enormity of this piece.
