This page features specimens from Nevada. 

The Andradite specimens shown here represent a small one time find from a small pod of skarn near the Cowboy mine.  I am offering the best of these on this site, and they are an exclusive.  There are no more, as the small deposit has been cleaned out.  It was a small pendant of limestone suspended in granitic rocks, converted completely to andradite and somewhat poor quality epidote as an associate mineral.  These are unusually bright for andradite, quite glassy in luster, and semi-gemmy...you can actually see into the crystals, which makes it difficult to photograph them.  If the crystal face is not reflecting light, you are actually seeing the interior of the crystal.  Color varies from a light cinnamon brown to a dark reddish brown.   These occur in narrow seams and frequently have some "damage" where the garnet crystals grew against the opposing side of the seam.   These are notable for the brilliance of the luster and the transparency of the crystals, it is quite rare to find andradite with both of these characteristics.
