Details:
This bright, cheery miniature specimen will be one of the cutest rocks in your fluorescent display. In white light, the calcite crystals are translucent white on a cleavage corner of pale greenish fluorite. It glows in complementary colors under all UV wavelengths, the calcite in red (brightest in shortwave), the fluorite in blue (brightest in longwave).
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.
