This beautiful blue banded agate geode comes from southern Brazil. Agate is a variety of silica with cryptocrystalline (very tiny) quartz crystals. The geode has been soaked in a blue dye solution which allows the agate to absorb the colorations. 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 quartz crystals grow towards the center in a geode pocket. The front of the rock has been cut and polished to a high gloss finish, while the edges of the stone have been left in their raw state. A cut and polished base allows this item to stand nicely on a desktop or shelf. The healing energy of Agate is used for strength and stability.
Approx. 4" L x 1.75" W x 3.25" H
