This pear-shaped Welo Opal exhibits intense flashes of orange, green, magenta, and even violet in a broad rolling pattern. The exceptional brightness is characteristic of fine-grade Welo material, which forms under volcanic conditions in silica-rich cavities. The vivid color seen here is due to optimal spacing of silica spheres, creating a strong diffraction of light. Ethiopia’s Welo deposit has become a major global source of gem opal, prized for its variety, hydrophane properties, and remarkable brilliance.
