Mexican fire opals are named for their uniform flaming orange or cherry red body color. They are always very brightly colored, and can be a little bit cloudy to almost perfectly transparent. Transparent specimens have a good luster. Like the traditional opal, fire opals can occasionally display signs of iridescence in very bright light.
