From the impressive finds of 2016 this is an nice example of this purple to blue color change Fluorite. The crystals are gem clear (this has been referred to as "Tanzanite Fluorite" due to the deep color) and most show slight wispy zoning or phantoms. The specimen is contacted on the backside and some crystals have a few rough spots so it is not right for a perfectionist but it still displays very well and is much more affordable as a result. The matrix is a duze of small Quartz crystals and the Fluorites are nicely perched on the matrix stalk. The color shift is seen under different light sources, ranging from a grape purple to indigo blue.
