Fluorite

Item Description

Two, large, lustrous and translucent, purplish-gray fluorite cubes, to 3.7 cm across are aesthetically emplaced on a bit of matrix. The crystals fluoresce a vivid purple (which is so vivid that the camera is having a tough time showing it amidst the UV light itself - but it really IS great in person as this is from the district from which the very word fluorescence was coined).
