This unusual specimen features a solid 3-dimensional mass of crystals of steeply curved fluorite octohedra, to 2 cm, perched OVER and smothering a layer of 3-dimensional green fluorite, and then coated at the edges by sparkling white quartz. The piece is complete all around save only a small bit of damage to the overlaying purple fluorite in one broken crystal on the far left side. The contrast is amazing! When backlit, the whole piece glows in 3 colors.
