Natural banded brown geode agate

Zoned agate in a geode features concentric layers of colors ranging from dark gray to reddish, highlighting the unique conditions of its formation. These agates are formed in volcanic cavities where silicon dioxide gradually crystallizes, accentuating the zoned patterns through mineral impurities. Primarily found in active or extinct volcanic regions, such as Brazil or Uruguay, their formation spans millions of years. Agate, known since antiquity, was used for its ornamental qualities.
