Opal types demystified: From fire to boulder and everything in between
Every opal is one-of-a-kind—and what this means to you is the power to express your individuality with something truly rare. Ultimately, you'll feel a quiet kind of confidence that shines through, knowing no one else in the world is wearing your exact piece.
Opals require very specific environmental conditions to form. A silica-rich solution must seep into rock crevices and slowly evaporate over millions of years. These conditions produce opals with signature "play-of-color," unlike the uniformity found in most other gemstones. Even in the same mine, one opal can flash neon green while another glows soft lavender. This is why opals have earned their rightful title: The Queen of Gems.
