Fluorescent Gallery- below are some photos and information about a few fluorescent minerals. They are some specimens we've sold in the past, but the photos remain up here for your enjoyment.
Hardystonite & Willemite with franklinite. FL SW: green (willemite) and blue-violet (hardystonite). The faint traces of orange FL in the hardystonite are clinohedrite; these two minerals often occur together. Hardystonite has been found only at Franklin, New Jersey and is named after Hardyston Township in Sussex County, the location of Franklin.
Meionite variety "Wernerite" - Ontario, Canada. FL intense yellow to yellow-orange in both LW and SW. The LW response is typically brighter, at least with "wernerite". Meionite is one of the two scapolite-group minerals (the other is marialite) which form a solid solution series with one another. From Canada comes the brightest-fluorescing meionite. Not all meionite is fluorescent, but much of it is weakly so.
Svabite - Langban, Sweden. FL orange SW. Svabite is a rare mineral of the apatite group. It occurs in metamorphic environments, specifically skarns. These can contain some of the most interesting mineral assemblages known to collectors.
Zircon & "Hyalite" in microcline - from the pegmatites of Antsirabe, Madagascar. Specimen also contains radioactive grains of monazite which in the daylight resemble embedded chunks of jeweler's rouge. Grains and partial crystals of zircon (var. "cyrtolite") fluoresce orange-yellow in SW UV. The green-FL coating is "hyalite" opal, an amorphous variety of silica which has traces of uranyl ion as the activator.
