SM460NX

Group of cubic Fluorite crystals, with staggered growths, in which a main one of 5 centimeters predominates. Of intense violet blue color and great transparency, its internal zoning parallel to the edges of the crystals stands out. The piece is accompanied by small hyaline Quartz crystals at its base and in the matrix.
