There's more than gold in them thar hills: South Dakota's thriving gemstone production.
Colored Stone 1992 Mar; 5(2):1
During the five years prior to 1991, the value of gemstone production averaged $112,000 per year, but in 1991 a single new producer, International Rose Quartz and Minerals Inc., entered the scene, producing gem materials worth millions of dollars. This firm's production catapulted the state from 25th into 2nd place in the United States in terms of value of gemstones produced. The value of South Dakota's gemstone production in years to come will depend greatly upon the ability to market materials such as rose quartz. If a stable market for carving quality rose quartz can be established, then the future of South Dakota gemstone production is very bright.
