Moss Agate

Montana Moss Agate is a type of chalcedony that is found in the Yellowstone River and its tributaries in Montana, USA. It is characterized by its translucent to opaque white or gray base color, with dendritic inclusions of iron and manganese oxides that create unique and intricate patterns resembling moss or trees. The formation of Montana Moss Agate is believed to be the result of volcanic activity and subsequent sedimentation, followed by the infiltration of mineral-rich fluids that deposited the dendritic inclusions. Montana Moss Agate is highly valued by collectors and lapid for its beauty and rarity.
