Fluorescent Minerals For Sale:  Page 2

Franklin & Sterling Hill

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.
Unless otherwise noted, multiple photos are different views of the same specimen.

Norbergite & Diopside - Ogdensburg, NJ.  FL yellow SW (norbergite) and blue-white SW (diopside).  The calcite has a very faint hint of FL response (reddish, SW).

Size:  display face approx. 3 1/4 x 1 7/8 inches (max. dimension).

Fluorescent minerals require a special lamp to view the colors you see in the photos. Most of the specimens shown above react to short-wave ultraviolet (SW UV or "UV-C"), which has a wavelength of 254 nanometers.

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, Hyalophane, 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, sometimes Microcline).  
Many fl. species fall into this category.

(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 ("+++").
