I purchased this at a store two months ago, but I've kept it stored in a dark place without taking it out of the box. The stones used are quartz, amethyst, and fluorite. I had the store clerk turn on the light to check the colors, and it shines in three colors: white, warm, and cool, each beautifully illuminating the stones when lit. Would you like to add this to your room's interior decor? Available for immediate purchase. Although it is new and unused, please refrain from purchasing if you are overly concerned about its storage at home. #PowerStone #Quartz #Amethyst #Fluorite
