Have you ever wondered what causes the spectacular iridescence or “play of color” in an opal?
Opals are made up of tiny spheres of silica, which are stacked on top of each other in a regular pattern.
When light enters an opal, it interacts with these stacked spheres (and the voids between them) and is diffracted, which means that it bends and splits into different wavelengths of light. The result is a play of color, where different colors are seen at different angles as the light waves interfere with each other.
The specific colors seen in opals depend on the size and arrangement of the silica spheres. The size of the spheres affects the specific wavelengths of light that are diffracted, while the regularity of their arrangement determines the strength and direction of the diffracted light waves. The colors can range from vivid blues and greens to warmer reds and yellows, and the exact combination of colors seen in an opal can be highly prized by collectors and jewelry enthusiasts.
The iridescence of butterfly wings and peacock feathers in created in a similar way but with different “building blocks.”
