I love this classic color from Illinois. Note the purple phantom. It's in good condition, it's gemmy so it looks richer in lower light. I included the second pic, where you can see the deep color saturation down the length of the crystal. This piece comes from the Les Tolonen collection. We purchased his high grade stash of Illinois fluorites, that took him over 30 years to accumulate. All the mines closed around 1994. If you don't have a blue Illinois fluorite, grab this one as they are few and far between!
