There are at least four strong phantoms in this wonderful fluorite cube from Illinois. The back is cleaved, but the bottom of the piece is crystallized so the piece is nearly complete all around. The middle of the cube is blue - perhaps the most desirable color in Illinois fluorite. There is a dark blue band through the blue core, as well as purple bands above and below. The banding is strongly visible from three sides and much better in person. This piece does not need special lighting to display: just a little ambient light at the right angle will do. Every year these pieces are getting harder to come by and more pricey. This one is a joy and a bargain...6 x 5.4 x 5.2 cm.
