Smithsonite


-

This mineral was named after James Smithson (1754-1829) the British chemist and mineralogist, a founder of the Smithsonian Institution in Washington, D.C., who distinguished the mineral from calamine (hemimorphite).

Sometimes it fluoresces. This little piece I have does light up brightly when illyuminated with ultraviolet light.
