Details:
This specimen, from the ancient lapis lazuli diggings in Afghanistan,
has a small crystal of
bright yellow-fluorescent marialite, accompanied by dark blue hauyne, partly altered to white gonnardite
. A bit of the hauyne
fluoresces orange under longwave UV; the gonnardite glows white under longwave and blue under shortwave. The calcite matrix fluoresces rich
red-orange
in shortwave, and some flakes of phlogopite mica glow bright yellow-white. That's five fluorescent minerals on one rock - and you don't have to pay postage and wait for delivery from Pakistan!
NOTE: TO VIEW FLUORESCENCE, YOU NEED A QUALITY ULTRAVIOLET LIGHT WITH A UV FILTER!
The better the UV source, the better fluorescent minerals look. Cheap "UV" flashlights without filters will not provide satisfactory results!
The photos here are taken using Convoy S2 and C8 (longwave-365)
and UV Systems SuperBright II (shortwave-254) lamps, metered
and exposed to show fluorescent response to best advantage.
Key factors include lamp wattage, UV spectrum and filtration, as well as distance from lamp to specimen. For best results with any UV source, observe against a dark, non-fluorescent, non-reflective background, in complete darkness with eyes adapted. For extended viewing, use protective UV-absorbing goggles.
