From: Minerva #1 Mine, Cave-in-Rock, Hardin Co., Illinois, USASize: 9.8 x 5.6 x 5.8cmWeight: 418g Wow! This is one of those Illinois fluorite mineral specimens that just blows your socks off! Incredible phantom color zones which go from a yellow core to a light purple, dark purple, and then blue. The condition is excellent - even the backside is mostly recrystalized. Just one small contact area near where it sits on the base, but the business parts of it are all in fantastic shape. This specimen comes with a labeled acrylic display base.
