Montana Moss Agate--A Great Rock to Tumble

Montana Moss Agate is famous for the "moss" patterns inside the clear to milky agate. The "moss" isn't really moss but water deposits. They form as black fern-like or tree-like patterns that resemble moss.

Often there is some redish to brownish banding. When you have both the moss and the banding it is quite spectacular. Unfortunately there isn't much you can tell from the outside.

These agate nodules are pretty bland on the outside. It's the inside you get excited over.
