This Celtic-looking fluorite pendant is gorgeous in both the purple and green color choices. The stones are large and almost give off a glow. In fact, fluorite has ultraviolet properties that can be seen with a black light. Thought to bring clarity and understanding to difficult or chaotic situations and enhance concentration, you might consider gifting this beautiful pendant to a student preparing for exams. It's a lovely gift for anyone. The green choice is unlike any other green gemstone you've seen.
