Own a masterpiece of natural geometry with these hand-polished Persian agate pairs. Each set features mesmerizing inner banding, where layers create an incredible structural rhythm. The sophisticated color palette transitions from icy-white chalcedony into a bold crimson red outer ring, encircling a vibrant, target-like center. These high-contrast mineral layers highlight millions of years of precision deposition, offering a sophisticated "fire-and-ice" aesthetic. The deep crimson red tones in these specimens are the result of iron oxide concentrations during the mineral's formation. These oxides permeate the silica, creating a rich, saturated color that contrasts sharply with the inner banding.
