Fluorescent Minerals For Sale:  Page 3

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.

Willemite & Calcite - Franklin, New Jersey. (#F496)


The willemite appears whitish in ordinary light.  The color becomes more of a pale sea-green in sunlight;  the sun's UV actually makes the willemite fluoresce somewhat, although it does not appear to "glow".  The NF matrix is primarily andradite garnet, franklinite (black) and hematite (brick-red).

Specimen has several very thin veins of a brick-red mineral that is probably serpentine colored by hematite.

Size approx. 3 1/4" x 2 1/8" x 1 1/2"

Actual weight approx. 14 oz.
