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.

Axinite & Willemite - Franklin, NJ (#F608)

Axinite with Willemite
Franklin, NJ.

The brightest variety of axinite is sometimes white, or nearly so, in daylight. Because this variety is very low in iron, it has a FL response that appears almost identical to that of calcite: intense red-orange. However, it lacks the "brief intense phosphorescence" of calcite, and furthermore axinite does not effervesce when treated with vinegar or dil. HCl.

Many people will mistake this rare variety of axinite for calcite, even insisting that it could only be calcite, simply because they do not know the daylight assemblages well enough to distinguish them. However, it is indeed axinite. You will not see many specimens of axinite this white in daylight or this intensely FL.

Size approx. 2 5/8" x 2 3/8" x 1 5/8"

Weight approx. 6 1/2 oz.
