Opal Gemstones: Unique Play-of-Color Gems for Custom Jewelry

A Gemstone of Light and Mystery

Opal is one of nature’s most enchanting gemstones. Each opal is truly unique—no two are alike—thanks to its mesmerizing play-of-color, a phenomenon caused by the diffraction of light through microscopic silica spheres. Whether you’re drawn to fiery oranges or subtle iridescent flashes, there’s an opal for every soul.

Origin and Symbolism

The word opal comes from the Sanskrit "Upala", meaning “precious stone,” and the Greek "opallios", “to see a change of colors.” These ancient names reflect opal’s timeless allure and shimmering mystery.

Jewelry and Care

Although delicate, opals make stunning centerpieces for personalized jewelry—especially earrings, pendants, and special occasion rings. With a hardness of 6 on the Mohs scale, opal requires thoughtful wear but rewards with unparalleled beauty. 

Birthstone and Celebrations

Opal is the official birthstone for October, alongside tourmaline, and is also associated with the 14th wedding anniversary. In various traditions, it has symbolized good luck, creativity, and emotional expression.
