Brazilian AGATE GEODES

Agate Geodes are found in the most southern state of Brazil, Rio Grande do Sul where millions of years ago ancient bubbling magma cooled and turned to basalt riddled with round-shaped cavities. The cavities later became filled with super- heated water saturated with silicon, oxygen and other trace elements causing beautiful layers of agate to form on the inside of the cavities. As the cavities became filled with agate, crystals of quartz would grow inside the hollow area left inside the cavity.
