Maury Mountain Moss Agate is an old stock Oregon Moss Agate and is generally what became the classic definition of a Moss Agate! It is generally composed of well defined multi color moss, and often takes a great polish! It has long since been mostly depleted, with only the occasional chunk being found at the now public digs. This old oregon classic is getting pretty hard to find!
