Cabinet, 11.8 x 7.5 x 7.5 cm
Denton Mine, Rosiclare Level, Harris Creek, Hardin Co., Illinois, USA

This perfect, sharp, gemmy crystal is like a jewel, shooting up from a minor matrix of fluorite - one of the finest Denton Mine or Illinois calcites I have ever seen, for my taste. Better in person, and complete all around! This was from the core suite of the Ross Lillie collection. Joe Budd photos.
