A zoned cubic Fluorite crystal attached to an aggregate of needle like, light brown colored Strontianite crystals along with some minor, white colored material labeled as Aragonite but likely Calcite. The Fluorite crystal is transparent on its outer layers which exhibit a light purple color, below which is a thin layer of dark purple which overlays translucent yellow/amber colored material. There are small Chalcopyrite crystals included within the yellow/amber material.
Flaws: The corner of the Fluorite crystal is slightly chipped and there is an internal cleave in the crystal.
