Adamite
Adamite is a zinc arsenate mineral. While pure Adamite is colorless, iron impurities give Adamite a common yellow hue. Green or turquoise colored adamite arising from copper impurities can also occur. The mineral is often found in association with hemimorphite, smithsonite, and other zinc-copper minerals in oxidized zinc deposits.
