About

380 million years ago, Africa collided with North America and forged the world’s purest quartz beneath Spruce Pine, North Carolina. Today that town of roughly 2,200 people is a leading reason the United States still holds a seat at the table in the global semiconductor trade: two local mines supply the high-purity quartz (α-quartz) behind as much as 90% of the world’s advanced chips — the cheapest and purest source on Earth, with no like-for-like substitute.
