About Opal

Stone Information & Mining

Opal is known for its unique display of flashing rainbow colors called play-of-color. There are two broad classes of opal: precious and common. Precious opal displays play-of-color, common opal does not. Opal is the product of seasonal rains that drenched dry ground in regions such as Australia's semi-desert "outback." The showers soaked deep into ancient underground rock, carrying dissolved silica (a compound of silicon and oxygen) downward. During dry periods, much of the water evaporated, leaving solid deposits of silica in the cracks and between the layers of underground sedimentary rock. The silica deposits formed opal. Play-of-color occurs in precious opal because it's made up of sub-microscopic spheres stacked in a grid-like pattern—like layers of Ping-Pong balls in a box. As the lightwaves travel between the spheres, the waves diffract, or bend. As they bend, they break up into the colors of the rainbow, called spectral colors. Play-of-color is the result. When Australia's mines began to produce opals commercially in the 1890s, it quickly became the world's primary source for this October birthstone.

Legend & Lore

Because opal has the colors of other gemstones, the Romans thought it was the most precious and powerful of all. The Bedouins believed that opals contained lightning and fell from the sky during thunderstorms.


Opal hues can range across the spectrum. An opal might display a single color, two or three colors, or all the colors of the rainbow. Opal displays background color in addition to play-of-color. Background color—also called body color—is caused by the suspension of tiny impurities within opal's silica spheres.


The only safe way to clean opal is with warm, soapy water.

Opal Splendor I absolutely love this ring! As an October lady, I'm thrilled to get three different opals in one ring. All my stones were beautiful. My small opals had as much fire as you could expect from a stone that size, mine actually had more fire than a lot of larger opals I have. This is a very unusual and unique combination of stones. I love having a ring that is different, especially in my birthstone. 07-28-10
Pretty sparkle The ring is agood substantial silver ring finished inside and out. The yellow and orange opals are lovely. I was hoping for more fire in the white opals but they are still pretty. 07-02-10
Poor appearance Save your money girls - this ring is not good on any level. It looks very inexpensive and the stones are unattractive. Not an appealing color combination, plus they are too bright - don't look real. If I write an unflattering review of a product, it doesn't get posted, so this one probably won't either. 06-30-10
