Margarosanite is a rare calcium lead silicate mineral that shows a beautiful short wave fluorescent response that ranges from blue/white to pastel shades of purple, pink and lavender. For these reasons it is one of the most coveted (and expensive) fluorescent minerals. First discovered in the Parker Shaft of the famous Franklin mine, in Franklin, Sussex County, New Jersey. A lesser variety of Margarosanite is also found at some of the mines in Filipstad, Varmland County, Sweden, such as Langban and Jakobsberg.
Note the red fluorescence under midwave.
