Montana Agate belongs to the Dendritic Agate group of Silicates with a hardness of 7. Dendritics display sharply defined two-dimensional, tree-like branching patterns within the stone. Creating lovely patterns for lapidaries and are desirable for cabochon cutting.

At Thomason Stone Supply we also believe that they are great for amazing beads with character and a unique addition to a necklace.
