About 15% of minerals will exhibit a visible fluorescence under shortwave or longwave ultraviolet illumination. The Geology.com Store has ultraviolet lamps, fluorescent mineral sets and UV-blocking safety

From April through October you can visit the Ben E. Clement Mineral Museum to participate in fluorite digs and after dark hunts for fluorescent minerals. A post on WhereToFindMinerals.com has information on how to get the most out of your
“Fish biofluorescence is especially common and morphologically variable in cryptically patterned coral-reef lineages. We identified 16 orders, 50 families, 105 genera, and more than 180 species of biofluorescent fishes.” Quoted from the PLOS ONE abstract. Related: Fluorescent
A few minerals have an interesting physical property known as “fluorescence”. These minerals have the ability to temporarily absorb a small amount of light and an instant later release a small amount of light of a different
The Mars Curiosity Rover has been out in the Martian night taking photographs illuminated by ultraviolet LEDs. NASA is looking for fluorescent minerals. Related: What are fluorescent
One of the most spectacular museum exhibits is a darkroom filled with fluorescent rocks and minerals that are illuminated with ultraviolet light. They glow with an amazing array of vibrant colors – in sharp contrast to the color of the rocks under conditions of normal
Another good show to attend if you are in the Louisville, Kentucky area November 12-13, 2011. The gym of the Resurrection Lutheran Church was filled with tables selling minerals, jewelry, fossils, geology supplies, art, and holiday gifts.The main display attraction is a set of fluorescent minerals presented by Danny Settles of Danville, Kentucky. He had three custom cases with shortwave, midwave, and longwave UV fluorescent minerals. The cases were contained in a black curtain area with an [...]
This fossil plate of a cluster of Sowerbyella brachiopod shells appears to have a unique property of fluorescence under longwave ultraviolet light (394? nm). My light produces a lot of visible purple light so the specimen appears quite purple with some orange-brown color on some shells. In person, the orange-brown color is much more pronounced.I believe the mineral present is aragonite with a manganese activator. Referring to the book The Uranium and Fluorescent Minerals: A [...]
