This pastel green, sparkling fluorite, exhibits unusual penetration twinning that APPEARS to be the product of two spinel-twinned crystals exhibiting some complex intergrowth between themselves. I don't know for sure...NEVER seen anything like it! The twinning actually appears to be more like cinnabar, which often exhibits star-shaped radial twins. The fluorite crystal is almost 4 cm in length so this is a full miniature, and it is complete ALL around as well as perched on a small bit of muscovite matrix. This really puzzles me! To that end, it is all the more valuable intellectually as well as for its striking symmetry. This is a unique piece, and a competition quality miniature of fluorite from ANY locality.
