Tumbled Moss Agate

These Moss Agate Tumbles come from Wyoming and Montana. This was a very popular material in the 60s and 70s and this stock was all polished in that time frame! These are highly fluorescent under 365nm blacklights! Simply lovely! Moss agate is a form of dendritic agate. Dendrites are tiny cracks filled with various elements (like manganese) from rain water that give a "moss" or plant like look.
