Ethiopian opal, a stunning gemstone with flaming flashes of red, green, blue, and gold, is renowned for its vibrant color play. Ethiopian opal stone was discovered in the Welo and Shewa districts of Ethiopia, and it has gained a lot of popularity due to its exceptional brilliance and translucency. In contrast to other opals, Ethiopian opals often possess a unique "hydrophane" property that allows them to absorb water and temporarily intensify their colors.
