Opal is a one of the mesmerizing and mysterious gemstones on the planet. Most opals have a white body color with a multicolor "play of color" effect that dazzles across the surface of the cabochon stone in the light. Fine opals can be hypnotizing! Most gem-grade opal historically has been found in Australia, but in recent years very fine and bright material has been coming out of Ethiopian mines as well. Black opals with dark body tones are extremely prized, and getting rarer with every passing year. Orange fire opals from Mexico are also very popular and often faceted, but only rarely exhibit play of color. Opal is the birthstone for October.
