NAEM; Rist Mine; American Gems Mine; LKA International Emerald Mine
A gemstone occurrence/mine located 1.2 km (0.75 mi) N of Hiddenite, on private land. Operated by Emerald Valley Mines (ID: 3101636) (1978). MRDS database stated accuracy for this location is 100 meters.
Originally known as the Rist Mine, but also known as American Gems Mine, LKA International Emerald Mine, and recently (since 1995), the North American Emerald Mine (specimen labels may be abbreviated NAEM = North American Emerald Mine). This locality is the type location for the chromian spodumene called hiddenite named for William E. Hidden and the town is named for the variety. This location is the most important North American emerald locality.
An Alpine-cleft emerald deposit. Local rocks include biotite gneiss and schist.
Workings include unspecified surface openings.
