About Powellite
Powellite is a calcium molybdate mineral that occurs in brilliant shades of yellow, orange, and pale blue, often displaying strong fluorescence under UV light. It forms as a secondary mineral in the oxidation zones of molybdenite deposits and in skarn environments, with fine specimens found in India, Morocco, and the United States. Its adamantine to resinous luster and fluorescent properties make it a highly desirable collector's mineral.
