Color-zoned cubic Fluorite crystals with attached Calcite. The Fluorite crystals reach 3.5cm on edge and are translucent with purple cores and blue outer zones. Smaller Calcite crystals are sparsley present on the font, with larger, denser Calcite crystal groups on the backside. Well crystallized all around and in great condition. Minor damage does not significantly detract. The depth of color and color-zoning is shown in the backlit photos.
