Fluorescence Spectroscopy and Zoning of Apatite
At the Rochester Mineralogical Symposium in 2022 Madeline Murchland gave a very nice presentation about fluorescence spectroscopy and zoning in apatite. Here is a recording of her talk.
31st Annual Ultraviolation 2021
Dennis Michaels (from our Fluorescent Minerals Facebook group) attended his first Ultraviolation show in Oct 2021. He took some amazing photos which really illustrate what this shindig is all about. Every rock is fluorescent. The room is filled with dealer and...
Multicolor Longwave Minerals
Everybody is familiar with mineral specimens that fluoresce two or more colors under shortwave UV light. Just think about a classical red-and-green calcite and willemite from Franklin. But are there similar multicolor specimens under longwave?? Mark challenged the...
Monteagle Miner Cave, a Fluorescent Chamber of Icicles
Over the 2018 holidays my daughters were in town. One left after Christmas but was replaced by my BFF Howie Green and his wife. Always looking for something to do besides explore the many fluorescent rocks down at my barn, this year we got lucky. My local glowhound...
Gaspeite: The Fluorescent Pretender
I’ve known more than one collector who has been enticed by the brilliant blue/green fluorescence of the mineral gaspeite. In fact, under the light of a Convoy S2+ long wave flashlight, this material can produce one of the brightest fluorescent responses of any...
The “Feldspar Effect”: Is This Really a Fluorescent Mineral?
There is something I call the "feldspar effect". When people first start collecting fluorescent minerals in the field they usually are amazed at the typical fluorescence of your average feldspar. As they gain experience and see more fluorescent minerals they realize...
Synthetic Fluorescent Halite
This article was originally published by Stefano Buzzoni on Nature's Rainbow.To produce crystals at home is an interesting experiment and if they fluoresce, could be “magic”. Furthermore, it’s easy and cheap. The only ingredient you have to use in big quantity is...
Gem Tabular Ruby Cluster: An Unique Crystal Habit
Most ruby specimens are either high-priced single/group of crystals on a marble matrix, or cheap massive habit rough from India. Not so here. This cluster of hundreds (or thousands) of intersecting crystals screams color and brightness, and has a delicate, not seen...
Pyromorphite and Plumbogummite – A Midwave Glow
There's been some cornfusion about the fluorescence of pyromorphite lately in the Fluorescent Minerals Facebook Group. I'll try and summarize, but invite others to wikify. For our purposes the nicest pyromorphite comes from the Bunker Hill Mine, Kellogg, Idaho, from...
Fluorescent, Phosphorescent and Thermoluminescent Fluorite from the Globe Mine (Rio Arriba)
This article was originally published by Stefano Buzzoni on Nature's Rainbow.This kind of fluorite was well described by Robbins (1984). “...This material is opaque, and greenish or gray in daylight. Under long wave, the fluorescence is violet. Under short wave, the...
