Opal is the world's most popular phenomenal gemstone, with many cultures believing that opals have supernatural origins and power. Inside each opal, sub-microscopic spheres are stacked in a grid-like pattern — similar to a layer of ping pong balls. When light strikes these spheres, the light waves bend and break into spectral colors, producing a flash of rainbow colors known as play of color. These round genuine opal cabochons display a translucent white background with medium to strong play of color ranging from blue, green, and red — making them a stunning choice for fine jewelry settings.
White opal is translucent to semi-translucent with play of color against a white background. Opal is the birthstone for October. Due to their delicate nature, opals require special handling and care.
