"You Find Em, We Shine Them!" Doc's Rocks Gem Mine is a Western North Carolina based gemstone mining operation in Blowing Rock Next To Mystery Hill. We purchase our mine ore from local North Carolina gem mines by the ton and resell it to the general public by the shovel full. Because of this, we can't guarantee what you'll find in the ore. However, if you don't find anything of value, we'll provide an equal amount of the ore you purchased for free so you'll have another chance to find something good. Once you find your treasure, Doc can personally facet your stone and set it into the jewelry of your choice. Distributed by Tubemogul.
