Cave in Rock, Hardin Co., Illinois, USA
Glassy crystals of purple fluorite. The fluorite crystals show several zones with inner phantom zoning of deep purple. The crystal surfaces have an intense square texture. Undamaged, backside was extracted from the rock. First foto with daylight as backlit, second and third photo with LED-light as backlit. A wonderful piece all in all.
