It was like the light inside a green and gold flecked fire opal.

They plan to control the demons with a fire opal.

From one finger of the left hand sparkled a strange fire opal.

Bliss dug out the fire opal, dropped it into his hand.

He opened the package; and took out a heavy gold ring in which was set a dark fire opal.

The stone upon the finger ring was a fire opal.

The hand that wore the fire opal picked up the envelope.

He was staring at the fire opal, as though suddenly fascinated by it.

With his left thumb, he turned the ring so that the fire opal was inward.

This was a girasol, or fire opal, of rare size.
