LONGWAVE FLUORESCENT MINERALS Collecting Longwave specimens is an excellent way to begin or expand your fluorescent collection. Great specimens are available for novice to advanced collectors. Longwave UV lights are inexpensive and easy to acquire. See our UV lamp page for more information. Click on any mineral photo for a expanded view. CALCITE Rhombohedrons Top picture is shortwave UV and second picture is longwave UV. Classic Calcite rhombs! I acquired a couple of flats of these beautiful rhombs a number of years ago and I am offering them now for the first time. Get one now while they are available!  Fluorescent in shortwave and longwave with an enduring blue phosphorescence when exposed to shortwave. A must have in any collection. From the Challenger Cave, Nuevo Leon, Mexico Average Specimen Size is 1" x 1 1/2" x 2" Item Code:  calrh 1001 $15.00 Note: Photos are for example only I will send a similar specimen.  First picture is under shortwave UV. The second picture is under longwave UV. CALCITE Outstandingly bright under both Shortwave UV and Longwave UV illumination. This CALCITE is a bright pink under longwave and a bright blue under shortwave. After exposure to shortwave, there is an enduring blue phosphorescence. Every mineral collection should be graced by one (or more) of these exceptional specimens from a mine closed long ago. From Terlingua, Big Bend, Brewster County, Texas. Cabinet size specimen is 1.5" x 1.5" x 2.5" Item code: tcal1021 $25.00 The specimens listed below are from a recent excavation by Mineralman in the CALICO MOUNTAINS, MOJAVE DESERT, SAN BERNARDINO COUNTY, CA. Mineral fluorescence is much more vivid in person than can be captured with a camera.   The minerals in these specimens from the Calico Mountains exhibit the following fluorescent color response: Colemanite- Blue/White and highly Phosphorescent Calcite- Yellow/ Cream Howlite- Purple/Blue       COLEMANITE ,CALCITE and HOWLITE Beautiful clusters of Colemanite (bluish/white), Calcite (yellow/cream) and Howlite (purple/blue) crystals. Excellent free standing cluster of crystals on top and a pocket of crystals on the side. Lots of smaller crystals disseminated in the matrix. Very fluorescent under short and long wave. Enduring phosphorescence when exposed to short wave UV but will also phosphoresce when exposed to long wave UV. This unique specimen location is referenced in "FLUORESCENCE Gems and Minerals under Ultraviolet Light" by Robbins.   Large cabinet size specimen is 5" x 4" x 3" Item Code: cole1002 SOLD Fluorite from the Rogerley Mine, England All Fluorite specimens were acquired in the year noted directly from UK Mining Ventures the authorized miners/operators. FLUORITE and GALENA Awesome longwave UV (and shortwave UV) fluorescent blue Fluorite from a now closed mine. Beautiful grass green Fluorite crystals and Galena crystals cover the matrix.

Specimen size is 6.15"x 4.45"x 2.50"  and weighs 2 pounds  Item Code: flu103 $400.00 for the "Turtle"     Fluorite on Celestite These outstanding specimens of FLUORITE belong to a VERY SMALL sub-group of fluorescent minerals. The fluorescence is due to hydrocarbon impurities incorporated within the crystal lattice of the FLUORITE during formation of the crystals and not to other elements as is the case with the vast majority of fluorescent minerals. A large pocket was discovered in November 2006 and specimens were acquired by me in January 2007. See the Dec. 2007 MINERALOGICAL RECORD vol.38, number 6 pages 478 & 479 for a discussion regarding this unique find. These are the finest Fluorite specimens to come from this location in over 50 years of mining!! These fine FLUORITES were photographed under longwave UV but are equally fluorescent under short wave UV. The phosphorescence is remarkable under shortwave UV, lasting several minutes (with a dark adapted eye) and noteworthy under longwave UV. Superb example of this very RARE fluorescent FLUORITE on CELESTITE are now available. Add one to your collection now while available. We may have to wait another 50 years for another unique find such as this! A rare and unusual find from the White Rock Quarry, Clay Center, Ottawa County, Ohio.   Fluorite with Celestite A rare and unusual find from the White Rock Quarry, Clay Center, Ottawa County, Ohio.
