Variscite

Variscite

Variscite is named for the old word for Vogtland, Variscia, which is the district in Germany from which Variscite gets its type locality. Generally, Variscite results from phosphate-rich waters interacting with aluminum-rich rocks. It can also be found on islands and in caves as a result of the phosphate provided by guano. Variscite is widely dispersed around the world at several localities. Sometimes used as a gem for jewelery.
