Several completely glass-clear, gem quality, emerald green Fluorite cubes comprise an aesthetic specimen from this well known and once prolific Fluorite mine in China.  The super lustrous, perfectly formed intense green cubes with sharp corners an edges are so transparent that you can see completely through the piece!  No matrix is present at the base of the piece for added rarity and aesthetics!  Additionally, rainbow iridescence is presented inside the colorless corner of the main Fluorite cube, outstanding!  This is from a recent 2020 small pocket discovery and only dozens of which were excavated, most of them are heavily damaged due to the harsh mining environment, I have acquired 2 pieces so far.
