The name "fire opal" describes the deep reddish-orange color of this gem material. Precious opal from San Juan del Rio varies in color from deep reds, to oranges, to yellows, to colorless. Some fire opal may display irridescent color (called "play of color") which changes with angle of observation. The above gem does not display irridescence, but the body color is a vivid orange (The yellow facet reflections in the above image are an artifact of the photography. The stone is a uniform orange color). There is little opacity ("sleepiness") in this stone. The facet pattern delivers excellent light return and scintillation. The facet meets, symmetry, and polish are all excellent.

Opal is relatively soft and is best used in jewelry settings that protect it from shock and abrasion. This stone would look beautiful in a pendant, pin, or special occasion ring.
