Fact check: TRUE-the purest quartz in the world.
Greg@gregtaniguchi
People always talk about rare earths when it comes to China, but in North Carolina, China can’t compete with Spruce Pine. For decades, Spruce Pine, North Carolina, has held a "near-monopoly" (roughly 80–90%) on the world’s supply of high-purity quartz (HPQ). The quartz in Spruce Pine is naturally about 99.9% pure right out of the ground, which is already exceptional. However, its real secret is low fluid inclusions.
