Description

Group of fluorite crystals with echeloned parallel growth, with marked faces and edges and damage free. Its honey color is very particular to this locality. Note that it is extremely fluorescent with a yellowish tone. Accompanied by white celestite crystals and disposed on a matrix with dolomite and calcite. It is difficult to find in the market pieces from this mine without damages, because they use to "fall down" in the vugs. An aesthetic American classic.
