Until now, the only lab created opal available had very consistent domains and color. Most of this consistency in color is maintained by using dyes. While many colors are available in other synthetic opal because the color is produced by dye, each piece of opal only contains one color and not much “play of color” if any. In other words, the color doesn’t change or move with different angles of light. This Cultured Opal does not use dye; all the color is the result of Bragg diffraction of visible light as occurs in natural opal. Furthermore, because their processes mimic nature, most pieces of opal have a diversity of color and depending on the angle of the light the opal will change color.
The unique qualities of each stone in its variety of forms will enable jewelry designers to conceive unique jewelry pieces with brilliant opal at a fraction of the price of genuine opal.
