Cat's-Eye Opal

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.
