At the Diamond Hill Mine you have the rare opportunity to collect your own crystals. We do not “salt” the piles. Its “unsalted”, meaning everything you will find came from this actual mine. Over millions of years, erosion has occurred to the southern part of the Appalachian Mountains which is one of the oldest mountain chains in the world. This has exposed a small 3 acre spot full of some of the widest variety quartz crystals in the world, known as Diamond Hill! Some of the best Amethyst, Smokey, Skeletal(Elestial), Angle Plated, Iron & Manganese Oxide coated, Aura, and other crystals are found here! Other minerals including Beryl, Garnet and Epidote have also been recovered!
