Hydrated Cobalt Arsenate:
Erythrite is a wonderful mineral for people who like striking, unusual colors. Its characteristic bright red purple color is very noticeable and was used to spot veins of cobalt bearing ore. Annabergite is bright green and the two minerals have the same structure but different chemistries. The unique red-purple color of Erythrite is very attractive, and its nice sparkle make this mineral a joy to add to your collection
