Diopside under shortwave UV Light



Same specimen as in photo DPS20a, showing the bright blue SW fluorescence of the diopside. Though it came from the Sterling mine, this specimen is from an area external to the Sterling Hill Zn-Fe-Mn orebody and thus has the typical appearance and fluorescence of diopside from the Franklin Marble.
