| Fluorescent minerals, when illuminated with only ultraviolet (UV) light
(invisible to the human eye) will emit visible light and appear to glow in
the dark.
Below is a gallery of Fluorescent and phosphorescent
minerals available for sale from John Betts - Fine Minerals in New
York City, NY. Fluorescent minerals found on this page include: Adamite,
Andersonite, Aragonite, Artinite, Benitoite, Calcite, Corundum, Fluorapatite,
Fluorite, Hemimorphite, Hydromagnesite, Novacekite, Phlogopite, Powellite,
Rhodonite, Sanbornite, Gillespite, Scapolite, Scheelite, Sodalite, Hackmanite,
Strontianite, Magnesite, Vlasovite, Gittinsite, Agrellite, Sapphire, Zircon,
Witherite, Willemite, Manganocalcite. Phosphorescent minerals continue to
glow in the dark after the UV light is extinguished.
Shortwave fluorescent lamps are relatively expensive because the filter on
the front of the lamp is made by only one supplier in Japan. Low wattage
shortwave UV lamps may be purchased for about $40, but to really enjoy
fluorescent minerals, you should buy a better lamp, with brighter wattage
(output) and expect to pay $300 (used) to $600. Look for brands like SuperBright,
TripleBright or Way Too Cool.
Longwave fluorescent lamps are much less expensive and are the type commonly
seen in mall stores selling fluorescent posters. They are less expensive
because the filters are not as expensive. I use an inexpensive flashlight-type
longwave UV lamp called a "Convoy S2" that are available from dealers of
Way Too Cool lamps for around $55.
The preview images below of the fluorescent minerals are illustrated illuminated
either with 254 nm shortwave (SW) or 365 nm longwave (LW) ultraviolet
illumination, causing them to fluoresce. To see photographs of these fluorescent
minerals under daylight illumination and larger UV illuminated images, click
on the preview photo. To purchase fluorescent mineral specimens from this
gallery, go to the

FLUORESCENT MINERALS UNDER SHORTWAVE UV
ILLUMINATION
The minerals shown below fluoresce under 254 nm shortwave ultraviolet
illumination. Ultraviolet illumination is invisible to the human eye. These
minerals absorb the energy of the invisible ultraviolet illumination, then
emit visible light in various colors. The result is that these minerals appear
to glow in the dark. Several of the minerals below also fluoresce under 365
nm longwave ultraviolet illumination, sometimes in a different color. Images
under both UV light sources are shown if the minerals respond to both
wavelengths.

FLUORESCENT AND PHOSPHORESCENT DIAMOND CRYSTALS
The diamonds shown below fluoresce under 365 nm longwave ultraviolet
illumination. Ultraviolet illumination is invisible to the human eye. These
diamonds absorb the energy of the invisible ultraviolet illumination, then
emit visible light in various colors. The result is that these diamond crystals
appear to glow in the dark. Some, as noted in the individual descriptions,
phosphoresce when all illumination is extinguished -- truly glowing in the
dark.
