Industrial cultured quartz crystal is electronic-grade quartz crystal that is manufactured, not mined. In the past, cultured quartz crystal was primarily produced using lascas. 1 as raw quartz feed material. Lascas mining and processing in Arkansas ended in 1997. In 2023, two companies produced cultured quartz crystal in the United States.
