The Many Faces of Fluorite

 
I'm frequently asked which rocks and minerals are my personal favorites. Well. If your list is like mine, it changes with the weather, the seasons, the wind! There's always a new find, new discovery, new technique, new something clamoring to get on "the list".
At the Tucson Rock & Mineral show this past February, however, an old favorite blew in with hurricane force – and I'm once again hooked! FLUORITE! I'm telling you, Fluorite is BIG this year, and the resurgence was apparent as many international vendors (especially China) showed up with fabulous Fluorite specimens. Naturally, I jumped in with both feet, and now I can't wait to share my excitement with you!

Here's a fun fact about Fluorite: Fluorescence gets its name from – Fluorite! And yes, Fluorite IS fluorescent under ultraviolet light. Some specimens fluoresce more than others, and there is an entire science behind UV light sources, such as short wave versus long wave (see link at end --). In the photo below, you can see the color change under a small, UV flashlight.

It's hard to resist the energy of these fabulous Fluorite personalities, right? There is a reason for that! A popular stone among energy workers, Fluorite is a well-known aid in clearing out murky energies, on many levels. Personally, I think of Fluorite as "the mental stone", and love to have it around my working areas. But you don't need to be a crystal healer to love Fluorite. Anyone can discover a favorite way to commune with this stone. It's all part of the adventure!

Ever heard of "Thermoluminescence"? It's the ability to glow when heated, a rare phenomenon occurring in only select Fluorite specimens. In the dark, the specimen will luminesce green to blue-green from body heat, electric stove top, heater coils, etc. But beware -- it's a one-time deal! Once seen, the glow will fade away, never to be seen again in that same specimen! No, I haven't tried this yet, but photos are available online (see link at end ~~~).

More fun tidbits:
  • Fluorite is second only to Quartz as the most popular mineral collected worldwide.
  • Fluorite is known as "the Most Colorful Mineral in the World".
  • Pure Fluorite is colorless. The striking colors are a result of impurities.
  • Green, Blue, Purple, Yellow and Clear are the most common colors, although any color in the spectrum is possible.
  • Microscope manufacturers use Fluorite in the production of lenses.
  • Fluorite was named in 1546 from the Latin word that means "to flow" because it melts easily.
  • Fluorspar is the name used for Fluorite when it is sold as a bulk material or in processed form
  • The "habit" of Fluorite is Cubic, and the color zones are often in cubic arrangement (much like phantom crystals in other crystals). So, a Fluorite could have a clear outer zone, allowing a colored cube to be seen inside.
  • Fluorite has perfect cleavage in 4 directions. Translated, that means that when the stone "cleaves" in all 4 directions, awesome octahedrons can be formed.
Amazing, aren't they? Are you now adding Fluorite to your own favorites list?
UVA Flashlight
Oh, by the way --- just for fun --- with ANY Fluorite item purchased this month on www.gemquarry.com I will happily include a small longwave UVA flashlight (a $6.99 value).

What a hoot to test your own new Fluorite specimen for fluorescence! You may even decide to make mineral UV a hobby, in which case you'll probably want to invest in a more expensive shortwave UV light.

And here's a tip: Once you've finished your testing, use your flashlight as a pet stain detector! It works!
As always, Chris and I thank you for the privilege of sharing our planet's wonderful rocks, minerals and crystals with all of you, our fantastic customers. Please join us in a toast to love, laughs, and new favorites!

Your friends,
 
Kathy & Chris
