Jewelry Trivia
Fire opal is also fairly transparent, but its background color may be yellow, orange, red or brown. Sometimes it doesn't even have the typical play of color. It's often called Mexican opal because Mexico is a major source of this type. Fire opal with a red body color is also known as cherry opal.
