It is a large cabinet specimen which shows much better in person. The Fluorite crystals are a light purple and are very glassy and lustrous. The larger crystals are up to 1cm in size and show no appreciable damage aside from a few along the edges. The color match in the photos are close but again show much better in-hand. I am assuming it is fluorescent, but cannot check since my UV light is dead. I've had it since I was eight!
