Description

Moctezuma Agate is a nodular banded agate found on the north end of the famous agate producing area in Chihuahua, Mexico. It is characterized by strong pastel colored banding. There has been no production of this agate for many years.

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.
