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.

Franklin / Sterling Hill "daylight" minerals now have their own page.

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 ... $46.00


Hydrozincite & Calcite - Sterling Hill, Ogdensburg, NJ.

A coating of hydrozincite (fl. blue SW) on a rock composed of calcite (fl. red SW), franklinite (NF) and zincite (NF).   The franklinite grains are rounded, making this kind of matrix somewhat friable.  However, specimen should remain intact if handled with reasonable care.

Size approx. 3" x 2" x 1 1/2"
Ship. wt. 1.7 lbs

#F578 ... $26.00
