Oscar Heyman fire opal rings

Fire opal glows with the fire of the sun: hot yellows, oranges, and reds so bright they look as though they might glow in the dark. Fire opal sometimes does have play of color like other opals but it does not need this to take a starring role in jewelry. Its juicy color is just the right accent to earth tones or black and also looks great paired with other bright tones.

Unlike most opal, fire opal is often faceted, so you can choose sparkle as well as color. Because it is light as well as bright, fire opal is especially good for earrings, where even small sizes have a big punch of color.
Fire Opal was born in fire, in the ancient volcanoes of Mexico. Fire opal forms when water seeps into silica-rich lava, filling seams and hollows. Under heat and pressure, the silica forms a solid gel, trapping the remaining water within its structure. Small pebbles of fire opal are found embedded in lava flows.
