Diamond Mountain Mining, Little Falls
This 187-acre Little Falls property is known among collectors for the oddities rather than the textbook crystals: black-stemmed scepters, gem barbells, large skeletal crystals, Cumberland habit gems, and hydrocarbon-included stones the operators call black diamonds. Digs are guided and by reservation only, worked with hand tools in a forested setting instead of a quarry floor. Because no rates are posted, settle the price when you book rather than at the gate.
