Ethiopian opal is the source designation for opal with some of the most intense play-of-color available in any natural gemstone: the Ethiopian opal's characteristic pinfire or broad flash patterns create a stone that appears to contain fire within it, cycling through red, orange, green, and blue as the viewing angle changes. At 1.49 carats of round Ethiopian opal in rhodium over sterling silver, these earrings deliver the full optical phenomenon of natural opal in a comfortable, secure setting. Each stone is unique - the play-of-color pattern never repeated across any two opal specimens. A genuinely phenomenal gemstone earring for the customer who appreciates the rare optical properties of natural opal.
