Scapolite (Meionite): Fl. lilac,
bluish, and violet, SW
Calcite: Fl. red-orange, SW
This page once had an overexposed, low-res
photo of a [presumably] Pb2+-activated fluorescent scapolite
from Sterling Hill. Finally, here's a
better photo; although it's a different specimen, it's from the same
galena-bearing scapolite occurrence at this locality.
Specimen size is roughly 2 1/2 inches. This
specimen came from the recent Super Digg at
Sterling Hill.
Aside from the galena and cerussite in this specimen, it is visually indistinguishable from the other chalky-white, weathered scapolites that came from the Noble Pit.
I used to take mineral photos with a 35 mm
camera; the response of ordinary "daylight" color film to fluorescent
minerals was unpredictable. It was still better than the digital cameras
of the day, though.
The newer digital cameras still don't capture
the colors perfectly, but this photo shows the subtle hues much better than
did the old one. Digital camera technology has certainly improved
in the past few years.
