More than 90% of the world’s precious opals come from Australia, and the rest can be found in other parts of the world such as Mexico, Brazil, Indonesia, Czech Republic, Ethiopia, and the USA. With seasonal rains, silica deposits are carried underground between the layers of rock. When the water is evaporated, these deposits form tiny spheres. Opal’s flashing play-of-color is caused by dispersion of light by silica spheres stacked like tiny ping-pong balls in a box. There are many legends from ancient peoples that try explain this phenomenon. In Australia, they believed that the creator came to Earth on a rainbow, leaving these colorful stones where his feet touched the ground. Today, opal is prized for its unique play-of-color, which is how its value is determined. The finest opals possess broad patterns over the stone’s entire surface, in which all the colors of the spectrum are represented.




The ancient Romans and Europeans believed opal to be a symbol of love, hope, fidelity, and purity because it encompasses all the colors of all other gems.  Many cultures have credited opal with supernatural origins and powers. The ancient Greeks believed opals gave their owners the gift of prophecy and protected them from disease. Throughout most of history, opal has been regarded as the luckiest and most magical of all gems because of its many colors.






There are over a dozen variations of opal. White opal is the most common variety, displaying a milkier color with hints of the entire rainbow- making it ideal for statement jewelry that can be worn with anything. The piece we recommend to wear with any outfit is our 18K white gold ring with a 1.78 carat oval opal. It is adorned with 112 fully cut diamonds and takes on the timeless halo style.

The Mexican Fire Opal gives off a glowing red-orange color, unique to its formation. It is created when water seeps into silica-rich lava. Then, under incredible heat and pressure, becomes trapped within itself. The result is a bold and breath-taking hue. Since the times of the Mayans and Aztecs, it has been regarded as giving its wearer confidence, energy, and joy. This Underwood pendant is made in 18K white gold and features a 3.04 carat cushion shaped Mexican Fire Opal and is surrounded by 25 fully cut diamonds.
