K109 Montana Moss Agate

K109 Montana Moss Agate


K109 This is 1/4 pound of tumbled Montana Moss Agate from Montana.  There are approximately 9-13 pieces per 1/4 pound. These stones will vary in size and shape.


Agates mostly occur as nodules in volcanic rocks or waters containing silica in solution possibly derived from the decomposition of silicates in the lava.  The siliceous matter is deposited in regular layers resulting in the banded or striped formation.
