Rare Coyamito Agate

Absolutely beautiful and rare Coyamito Agate from Chihuahua, Mexico, which is the only place in the world they are found! The formation of Agate is most often from deposition of layers of silica filling voids in volcanic vesicles or other cavities. The layers form in stages with some of new layers providing an alternating color.
