Important:  Fluorescent minerals require a special ultraviolet lamp to view them (normally, a short-wave UV lamp).  It's worth it to get a good lamp.

The color response of your computer's monitor may not be the best representation of the photographs. The colors shown in the photos, at least as they appear on our office monitor, are the most accurate representations we were able to capture with the limitations of the camera.

Fluorite ("Chlorophane"), Fluorapatite, & Willemite - Franklin, NJ (#F601)

Fluorite with Fluorapatite and Willemite
Franklin, NJ.

Pale aqua-fl fluorite, the variety known as "chlorophane". Unlike most fluorite, this variety does not FL much in LW UV, being instead mostly SW. It also gradually loses its FL response with exposure to visible light, meaning it should be kept in a light-proof container when not being viewed. Loss of FL happens most quickly with sunlight (couple days or less). The willemite (fl green SW) and fluorapatite (fl orange SW) are unaffected. Ordinary viewing in room light for brief periods does not affect chlorophane much, if at all.

The fluorapatite FL a bit better in real life than shown in photo.

Size approx. 2 1/4" x 1 1/8" x 1 1/4"

Actual wt. about 6 oz.

#F601 ... $15.00

Hardystonite, Willemite, & Calcite - Franklin, NJ (#F589)

Hardystonite, Willemite & Calcite
Franklin, New Jersey

Deep-blue-violet FL hardystonite with green-FL willemite and red-orange FL calcite.  A 3-color short-wave fluorescent specimen.
This one has three fresh surfaces, with a weathered one on the "bottom" of the piece where it sits on a display shelf.  This looks like Buckwheat Mine assemblage and (we believe) was collected at the Buckwheat Dump years ago;  good hardystonites from this sub-locality within Franklin are not at all common. 

Size approx. 3 1/4" x 2 1/2" x 1 3/4"
Ship. wt. 1.5 lbs.

#F589 ... $43.00

A very dense "ore rock" with compact franklinite and pale tan willemite.

Size approx. 4" x 2 1/4" x 2"

Ship. wt. 2.5 lbs.

#F600 ... $22.00

Willemite & Calcite - Franklin, NJ (#F571)

Willemite with Calcite in Rhodonite - Franklin, NJ.

The rhodonite (NF) is pinkish-gray in daylight and has willemite interspersed throughout.  The willemite is visible in SW UV as green fl. 

Overall it bears some resemblance to "fluorescent concrete", but this is a natural rock. 

Size:  about 2 1/4" x 2 1/2", thickness 1 3/8" tapering down to 1/8" (wedge-shaped cross section)

Ship wt. 0.7 lb

#F571 ... $18.00
