Locality: Franklin Mine, Franklin, Sussex County, New Jersey, USA (See on Mindat)

Description:
Willemite and calcite are staples of the Franklin Mine; scapolite, quartz and pyroxene, probably less so. Here is a small, but nevertheless interesting specimen that hosts all five. The scapolite is of the variety meionite and shows a magenta hue. The calcite, red. The willemite, green. The quartz and pyroxene, no glow at all; the latter being the black material in natural light.
