Opals are composed of tiny spheres of silica, arranged in a regular pattern that acts as a diffraction grating. When light strikes these spheres, it is diffracted in different directions, creating a spectrum of colors that dance across the opal’s surface. This phenomenon, known as opalescence, is responsible for the gemstone’s captivating play of colors.

- Body Color: The underlying color of the opal, such as white, black, or blue, affects the overall appearance and intensity of the play of colors.
- Pattern: The arrangement and size of the silica spheres determine the pattern of the play of colors. Common patterns include harlequin, pinfire, and broad flash.
- Transparency: The transparency of the opal affects the amount of light that can pass through and interact with the silica spheres, influencing the intensity of the shine.
