A beautiful “fluorite geode,” continuing numerous deep purple fluorites of the variety that has been marketed as “tanzanite colored.”    Most fluorite specimens, especially from China, seem to be flat plates, or clusters of crystals.  Seldom do you get this geode-like appearance, and the contrast with the white quartz combined with the small windows at the back and the luster of the fluorite, make for a particularly beautiful display.  The level of sparkle that comes off this piece, especially under LED lighting is quite nice as well. 

It's a bit hard to focus because of the three-dimensionality of the piece, but it really is better than the pictures show, with a much sharper, cleaner appearance.
