A sublime, cornflower-blue Fluorite from the famous Minerva #1 Mine with such nice color saturation is hard to find! The crystals are gemmy, with good luster. The faces, though reflective, are very finely stepped, creating an almost silky appearance in side-lighting and looking more gemmy from the front. There are numerous color zones within the crystals: starting with light purple cores, dark blue, and then lighter blue. Each of these zones has even finer phantoms defining them, the closer you look! Seldom do we get this quality without any damage, but this is nearly pristine and it displays very dramatically. More gemmy in person.
