Tanzanite Fluorite

These large, sharp, deep purple-blue crystals are often called "Tanzanite Fluorites" in China for their unusual strong color, and that they do change color between sunlight and internal light to different hues ranging from blue-purple to purple. These came out in 2017, and not since. Fascinating specimen, because it is so thin that it shows such great translucency!

"tanzanite" fluorite material has been appearing in dealer's stock. It's very attractive stuff which gets its name 'Tanzanite Fluorite" from the fact that the fluorite's color looks like the blue of tanzanite.
