Minerals For Sale: 

Alleghanyite Specimen

This is a more detailed listing of a mineral from the main category page, Daylight Specimens of the Franklin-Sterling Hill Area.

Fluorescent minerals have their own pages, starting at this link.

For an explanation of abbreviations used, please see our guide to mineral sizes.

Sterling Hill
Ogdensburg, NJ

Sparse microcrystals of alleghanyite (or possibly sonolite) with an unidentified light-tan or beige mineral that may be altered alleghanyite / sonolite.  There is also willemite (FL green SW), franklinite, and non-fluorescent calcite.

The alleghanyite crystals are brown to sherry-colored.

An old label says "Alleghanyite", but a tiny label attached to the rock itself says "Sonolite".  It is probably alleghanyite, but then again both minerals can look alike and occur in similar assemblages.

Both species are rare.

Specimen has a Gary Grenier collection number on it.

Specimen Size:  approx. 4 1/4" x 2 1/2" x 3/4"
Ship. wt. 1 lb
