331 McKinney Mine Rd.
Looking for an experience that’s “out of this world”? Emerald Village offers night-time underground mine tours that unlock vibrant hidden colors available only under ultraviolet light, commonly called black light. The brilliant coatings in the Bon Ami Mine are largely deposits of Hyalite Opal, a true form of opal found in this area. Under shortwave ultraviolet light, these coatings fluoresce or glow a vivid lime green. The effect, underground at night, is stunning!
