Occasionally, colors of purple, orange, brown, pink, and yellow can be found as well, although the latter colors are rare. Prized for taking a great mirror shine when polished, this also a highly preferred tumbling material due to its variety of patterns and colors that can be exposed from the tumbling process, including the opportunity for rare and unusual color combinations. Botswana agate is formed naturally over time by the earth's activities. The agates were formed during ancient lava flows when liquid magma settled into fault lines. When the liquid magma cooled, silica acid transformed from a liquid gas to a solid material. The thin layers of silica acid created the fine banding found in agates.
