Quartz, variety amethyst, is SiO2 and is prized for its violet-purple color. In this case, we see an orange color as the result of Iron. The name comes from Greek, meaning “not drunk,” and the mineral was first described by Georgius Agricola in 1546.

The quartz from this area is dominated by amethyst, but it also occurs in white, gray, mauve, reddish-purple, brown, and yellow varieties, making it a favorite among mineral enthusiasts.
