Dig your own crystals! Visit Arkansas' premier crystal shop, featuring public mining at the Ocus Stanley Claim on Fisher Mountain (opened in 1946, it's the oldest public quartz dig in Arkansas), private crystal digs, artisanal coffee and snacks at our Lemurian Roast coffee shop, and a free museum with America's largest turquoise nugget (249 lbs) from our Mona Lisa mine! All of our crystals are ethically and sustainably mined by hand. Our hours are 9 a.m. - 5 p.m. Tuesday through Sunday.
