Collection: Opal

Synthetic opal is a lab-created gemstone formed through a controlled process that arranges microscopic silica spheres into a precise, repeating lattice — the same ordered structure responsible for natural opal's mesmerizing play-of-color. As light diffracts through these stacked spheres, the material flashes with shifting spectral colors that shimmer and change as the stone is turned. This collection includes opal in several resin contents — from resin-free (0%) to 15% and 80% — so you can choose material suited to your project, whether you want the harder, more heat-tolerant nature of resin-free opal or the easier cutting and greater stability of higher-resin varieties. Available in a wide range of body tones and bold color patterns, lab-created opal delivers the fiery brilliance of fine natural opal with remarkable consistency, making it a striking choice for cabochons, inlay, and jewelry.
