This large and impressive fluorite cluster from the Denton mine in Illinois has complexly zoned, yellow and purple crystals that reach 7.0 cm across on edge! The piece consists of a large, pronounced, corner-up fluorite with a single step in the rear of the piece with two large, juxtaposed crystals in the front. The color-zoned phantoms start with pale yellow cores that are demarcated by a 2.0 mm dark purple band followed by a 5.0 mm pale purple zone that is rimmed by a distinct, dark purple zone and then several alternating pale blue and darker blue phantoms that are again defined by another distinct, dark purple zone and then a few alternating, thin, blue-purple and purple zones out to the margins of the crystals - the more you look at it, the more zones you see. Like many of these, it is dependent on a little backlighting but it is very translucent, and needs little light to show it's true colors. Complex and beautiful old classic American specimen! Ex.
