Phosphosiderite is a rare mineral named for its main components, Phosphate and Iron. The Siderite at the end of Phosphosiderite comes from "Sideros", the Greek word for Iron. It was discovered in 1890 and is mined in some parts of Chile, Argentina, Germany, Portugal, and the United States. Phosphosiderite is often found in a bright orchid-purple tint with yellow-colored streaks. The vein-like streaks found in the stone are known as Cacoxenite. Four other rare color variants are rose red, brown-reddish yellow, mossy green, and dark shades of purple.
