CV51AD9: Druse of cubic Fluorite crystals that are between transparent and translucent, very bright, with white inclusions. They have an intense green color that passes to violet in sun light. The matrix is fossil coral which indicates that the sample was mined in an old area in the mine, so was mined in the past. The sample is from an old collection.
