Variscite

AlPO4·2(H2O)

Variscite is a hydrous aluminum phosphate. It was first discovered in the Vogtland District of Germany. The material is usually veined with other minerals such as millisite or wardite. Colors of varisite vary only slightly between yellow green to slightly darker greens. The material is often misidentified as turquoise. Variscite is actually quite rare and beautiful. It is inexpensive because it is not a well known, therefore there is little demand for it.
