1.6" Amethyst Crystals on Fluorite - Nancy Hanks Mine, Colorado

This is a unique formation of lilac-purple amethyst crystals over a bed of massive fluorite, creating an attractive color contrast. It's old stock material that came out of the Nancy Hanks mine in Mesa County, Colorado, collected when the mine was still in operation.

The fluorite exhibits a stunning blue fluorescence under shortwave ultraviolet light.
