COQUIMBITE SPECIMENS

Coquimbite is a rare, hydrated iron sulfate mineral, often found in arid environments. It typically forms as a secondary mineral in oxidized iron sulfide deposits and can be purple, greenish, or greenish-yellow in color. Coquimbite's name comes from the province of Coquimbo, Chile, where it was originally discovered. It is known for its prismatic crystals, but can also be found in massive form.
