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

Willemite & Calcite - Franklin, NJ. This willemite is in the form of rough crystal shapes in the calcite.
What's especially interesting is that they appear to be made of both
willemite and tephroite, the willemite forming FL green "exsolution
lines" within the NF tephroite.
The crystal shapes are ash-gray with a greasy to vitreous luster;
this is typical for tephroite. The outer rims are made of red
Some surface contacts and edge dings to the calcite; specimen is
priced accordingly. However, they don't really have any effect on the FL qualities.
Specimen size approx. 3 1/4 x 2 1/2 x 1 1/2 inches
Ship wt. 1.2 lbs.

Willemite & Calcite with Rhodonite, Andradite, and unidenfied minerals - Franklin, NJ.
This one has a couple of unidentified silicates. One of them is a
deep reddish-brown mineral with a dull or waxy luster. It
could be friedelite.
Some of the rhodonite (if that's what it is) has an almost platy quality.
Together, these minerals make for a very interesting daylight specimen
(see photos). The rock is very dense and compact,
having several different minerals in various daylight hues of tan,
pink, brown, and brick-red. Overall, they give the specimen
that hard-to-define "classic Franklin" appearance.
Specimen size approx. 3 x 2 x 2 inches.
Ship wt. 2 lbs.

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.

Hardystonite, sometimes Microcline).
Many fl. species fall into this category.
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 ("+++").
