Fluorite crystals of a vivid Deep Blue, with shades that vary between indigo and navy blue on a matrix of white crystallized Quartz.
The smaller Fluorite crystals are neatly cubic, with small dodecahedron bevels and with very well defined curvatures on faces and edges, while the largest ones are unusually strongly rounded, a very uncommon shape for Fluorite.
This shape is due to the balanced forms of the cube, polycrystalline and deeply edged, and the smooth dodecahedral faces, both dodecahedron and cube have curved faces and edges.
