- Calcite With Fluorite
- Denton Mine, Cave-in-Rock, Hardin County, Illinois, USA
- Cabinet, 12.1 x 7.1 x 5.1 cm

A large crystal of gemmy, doubly-terminated, golden calcite measuring a whopping 11.0 cm across contrasts beautifully with its matrix of deep lavender, translucent, fluorite. This is certainly one of the largest and gemmiest of the style I have seen from the mine, which is now defunct as is the rest of the old fluorspar district here. The piece is really striking, in person, and has a pronounced internal luster to it.
