What is this specimen? Be specific (this is a variety of a mineral on the list). 2. After prolonged exposure to UV light, what will happen to the color of this specimen? 3. Describe the property demonstrated in Question #2. 4. Name a chemical difference between this mineral and its "parent" mineral (e.g. Goshenite's "parent" mineral is Beryl).
