What is Cat's Eye Opal?

Rarely, opal will have fire that yields an optical effect similar to a cat's eye. In these opals a thin line of fire will be visible from multiple directions and track back and forth across the stone similar to the cat's eye known in other stones. Shown here is a cat's eye opal from the Constellation Mine in Spencer, Idaho. It is four millimeters round.
