Fluorite from the William Wise Mine, Westmoreland, New Hampshire

No. 423: Ember Cut, 7.32 ct., 11.9 x 10.3 x 8.9 mm, VVS, $102.48

Fluorite is a very soft mineral and therefore unsuitable for use in jewelry. Because of its softness and ready cleavage, fluorite is very difficult to facet. The fluorite from the William Wise Mine is unusually free of inclusions and displays an exceptionally beautiful green color. The beauty of Wise Mine fluorite justifies the extra effort required to facet this gem material. Shown above is a rare gem that would be a fine addition to any collection. If you are a collector of fluorescent gemstones, this specimen has a bright blue fluorescence under long wave ultraviolet ligth.

Fluorite from the William Wise Mine, Westmoreland, New Hampshire

No. 432: Maltese Cross Cut, 21.46 ct., 16.2 x 16.2 x 12.2 mm, VS, $278.98

Fluorite is a very soft mineral and therefore unsuitable for use in jewelry (Unless you can find a metalsmith that can dream up a way of setting the stone that doesn't involve forcing metal over the girdle edges). Because of its softness and ready cleavage, fluorite is very difficult to facet. The fluorite from the William Wise Mine is unusually free of inclusions and displays an exceptionally beautiful green color. The beauty of Wise Mine fluorite justifies the extra effort required to facet this gem material. Shown above is a rare gem that would be a fine addition to any collection. The Maltese Cross cut delivers good scintillation, even for a material with a refractive index as low as that of fluorite. When viewed squarely to the table facet, a Maltese Cross can be viewed in the pavilion.

Fluorite from the William Wise Mine, Westmoreland, New Hampshire

No. 434: Square Brilliant Cut, 16.43 ct., 14.6 x 14.6 x 12.1 mm, VS, $213.59

Fluorite is a very soft mineral and therefore unsuitable for use in jewelry. Because of its softness and ready cleavage, fluorite is very difficult to facet. The fluorite from the William Wise Mine is unusually free of inclusions and displays an exceptionally beautiful light green color. The beauty of Wise Mine fluorite justifies the extra effort required to facet this gem material. Shown above is a very bright, clean and expertly crafted gemstone suitable for any gemstone collection. If you are a collector of fluorescent gemstones, this specimen has a blue fluorescence under long wave ultraviolet light.

Fluorite from the William Wise Mine, Westmoreland, New Hampshire

No. 529: Modified Rosary Cut, 12.8 ct., 11.8 x 11.8 x 10.4 mm, SI1, faceted by R. Drummond, $192.00

Fluorite is a very soft mineral and therefore unsuitable for use in jewelry. Because of its softness and ready cleavage, fluorite is very difficult to facet. The fluorite from the William Wise Mine is unusually free of inclusions and displays an exceptionally beautiful light green color. The beauty of Wise Mine fluorite justifies the extra effort required to facet this gem material. Some colorless fluorite from this mine can be treated with high energy particles (i.e. irradiation) to induce a gorgeous turquoise-blue color. Shown above is an expertly faceted fluorite cut from irradiated Wise Mine fluorite. I have had a difficult time achieving an accurate color reproduction for this gemstone; it is best described as a medium, slightly greenish-blue color. This specimen would be a beautiful and unusual addition to a gemstone collection.

Fluorite (variety: chlorophane) from the McHone Mine, Spruce Pine, North Carolina

No. 764: Cut Corner Barion Square Cut, 3.93 ct., 9.0 x 9.0 x ~7.8 mm, VS, faceted by Robert Drummond, $373.35 Sold

Recently, a small pegmatite vein near Spruce Pine, North Carolina, has begun to produce one of the rarest of all forms of fluorite, chlorophane. Chlorophane is distinguished by the unusual physical properties; phosphorescence and thermoluminescence. Much fluorite is fluorescent, showing a blue to green glow when illuminated by long-wave or short-wave ultraviolet light. Chlorophane is remarkable because it phosphoresces. When illuminated with either visible or ultraviolet light, and then viewed in the dark, chlorophane glows a greenish-blue color for several minutes. If a piece of chlorophane is heated with a flame or electric coil, it will emit a strong bluish-green color visible even in daylight! If the above gemstone is placed in your hand, then viewed in total darkness, the warmth of your hand will cause a faint bluish-green glow. This is an extremely rare phenomenon for any gem material. What is even more unusal about this particular chlorphane is its color. This gem shows a distinct alexandrite-like color change. Viewed under tungsten light the gem shows a somewhat rosy-lavender color. Viewed under fluorescent light the gem appears a grayish-green color. In sunlight the gem is a grayish-blue color. Such remarkable color change has not been reported for other varieties of fluorite.

Fluorite is far too soft and fragile to be of any use in jewelry. This is strictly a collector's gem that must be handled with "kid gloves." This particular gemstone has been expertly crafted. The polish, symmetry, and optical performance are all fine. If you purchase this faceted stone, a small parcel of chlorophane fragments will be provided for you to observe thermoluminescence. We certainly do not recommend that you apply strong heat to the gemstone! Only one or two world locations have ever produced chlorophane suitable for faceting. To the best of our knowledge, this is the first faceted chlorophane fluorite to ever have been offered for sale on the internet. Until now, few, if any, faceted chlorophane fluorites have ever been cut.

Fluorite from the Rogerley Mine, Cumberland County, England

No. 728: Mountain Lily Cut, 5.20 ct., ~13 x ~13 x ~8.5 mm,VS, faceted by R. Drummond, $312.00 Sold

Recently a group of mineral miners have reopened an old limestone quarry, the Rogerley Mine, in Cumberland County, England, to recover unusual gemmy green fluorite crystals that fluoresce a bright blue. The unusual aspect of this green fluorite is that it shows this strong blue fluorescence even under sunlight or ordinary incandescent light. The fluorite from this locality is an unusually deep green color. It can be faceted to yield spectacular collector's gems.

Fluorite is a very soft mineral and therefore unsuitable for use in jewelry. Because of its softness and ready cleavage, fluorite is very difficult to facet. In spite of its softness, when properly faceted, fluorite gemstones can display good scintillaton. Shown above is an expertly crafted Rogerley mine green fluorite. This gem does not disply the strong blue daylight fluorescence of the orignal crystal; probably because the trace elements responsible for the fluorescene were localized in the outter layers of the original crystal. Even without the blue fluorescence, this is a gorgeous deep green fluorite gemstone. It would be a fine addition to any collection.

Fluorite from Kadipani, India

No. 659: Curved Triangular Brilliant, SI1, 8.69 ct., 13.8 x 13.8 x 9.0 mm, faceted by: R. Drummond, $104.28

This is definitely a collector's gem. Fluorite is a very soft mineral; the Mohs hardness is only 4. Because it is so soft, faceting fluorite is a true "tour de force." It is very difficult to obtain a fine polish on facets, and facet junctions on cut fluorites tend to be rounded rather than sharp. Fluorite comes in a variety of colors including beautiful purples, yellows, greens, pinks, and blues. Fluorite is almost never set in jewelry because it would easily scratch or fracture. If you know a masochistic metalsmith, you might induce them to attempt to set a faceted fluorite. If successful, the finished piece would definitely be a unique creation. For the less venturesome, this gem would look great sitting in your cabinet with other rare gemstones. Fluorite crystals are normally heavily included. The above gem does contain eye-visible inclusions, but this is still a beautiful stone.
