Group of very well defined fluor-uvite crystals with a characteristic olive green color, with an excellent transparence. They are disposed on a matrix formes by magnesite crystals, between transparent to translucent. The contrast with the matrix is very aesthetic. Most specimens historically designate as uvite are actually, as analyses have shown, the F-dominant end member: fluor-uvite. Those from this mine have been shown to be the fluorine phase.
