Montana Moss Agate is found on the river banks and sandbars of the Yellowstone River between Sidney and Forsyth, Montana. Montana Moss Agate typically features colorless, yellow to reddish brown, or gray to blue translucent agate. Dendrites or ribbon banding in black, red, or orange are typical. Some Montana Moss Agate nodules are partial limb casts from the volcanic flow that caused its formation, and can show patterning and shape similar to petrified wood.
This is select material, mostly whole nodules or partial nodules of good quality.
