Natural Banded Agate Bookends

These gorgeous banded agate bookends come from southern Brazil. The banded agate portion contains beautiful earth and tan tones surrounded by quartz crystals which have sealed the geode. The coloration of these bookends formed naturally within the stone. Agate is a variety of silica with cryptocrystalline (very tiny) quartz crystals. The agates formed within air pockets of hardened lava. Silica rich fluids flowed through these air pockets and began to cool and harden. Layer upon layer of silica built up within the pocket, creating beautiful bands of the mineral Agate. Sometimes these layers completely fill the original void and sometimes larger crystals grow towards the center in a geode pocket. The front, bottom and inner sides of the rock have been cut and polished to a high gloss finish, while the back of the stone has been left in its raw state. The healing energy of Agate is used for strength and stability.
