Fluorescent Minerals For Sale : Page 2
Daylight specimens are in Minerals A-L and Minerals M-Z.Fluorescent cabochons are in the Cabochons section.
Fluorescent sets are in the Mineral Sets section.
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.

Willemite - unusual specimen of willemite veins through a piece of dense andradite - franklinite matrix. We've never had a willemite like this. Call it "Tiger stripe willemite", perhaps. The NF matrix provides stark contrast. The rock appears drab in daylight, making the willemite almost invisible until SW UV is shined on it.

Willemite & Calcite - Franklin, NJ. Cut and polished halves or slabs, sawn from the same rock. The backs are rough and show weathered surface; the fronts have a matte to medium gloss polish.
The pieces do not stand up by themselves but would sit up nicely if you had a pair of easels.
Ship. wt. 3 lbs.
#F428 .................... SOLD
Willemite & Calcite - Franklin, NJ. Pattern piece with nice contrasting zones of red (calcite) and green (willemite) against non-fl black areas (andradite and franklinite). There is also a mostly intact willemite crystal in this specimen, along with a larger but partial one.
Specimen is about 3" x 2 1/2".

Abbreviations:
FL = "fluorescent", "fluoresces", "fluorescence";
LW= "Long-Wave" (ca. 320 to 370 nm);
MW = "Mid-Wave" (ca. 302 to 312 nm);
NF = "Non-Fluorescent"
PH= "Phosphorescent" ( i.e., temporary glow after UV source is removed);
SW= "Short-Wave" (254 nm);
UV= "Ultra-Violet".
Brightness Grades:
* = Weak (Scapolite, Microcline, some Fluorapatite).
Requires a powerful UV lamp and well-adjusted eyes in a darkened room. Don't ignore this category; some of the nicest color combinations are here.
** = Moderate (Fluorapatite, Hardystonite).
Many fl. species fall into this grade.
*** = Intense (Willemite, Scheelite).
The fluorescence has an almost electric quality when illuminated with UV.
Brightness Grades are somewhat subjective, but willemite and scheelite are almost always Grade 3 ("***").
