A classic example of Ethiopian Welo Opal, this translucent cabochon displays vibrant flashes of green, yellow, and red across a milky base. The play-of-color is caused by microscopic silica spheres within the opal that diffract light into spectral colors, with the exact pattern and intensity depending on the uniformity and size of the spheres. Mined from the Wollo (Welo) Province in Ethiopia, this deposit has become renowned since its discovery in the late 2000s for producing high-quality hydrophane opals with striking brightness and broad color ranges
