At this time Avalon Crystals has only one stone to offer that starts with the letter (Y) "Youngite" As a healer, I've been working with this unusual stone from the state of Wyoming. It's said that it will help us to discover the inner child within us all. It's also said to be good for remembering childhood experiences. Youngite will also fluoresce under a black light, displaying a beautiful pastel blue to green color. Being that Youngite is also covered with tiny colorless drusy or druzy quartz crystals, it truly does make for a spectacular mineral for the specimen collector!
