I will attempt to categorize opal colors as best I can. Some opals possess all the colors of the rainbow but never in regular lines or bands - more like an abstract painting or a random composition.

Opal Colorsĭescribing the color of an opal is not simple. They can be a single vivid color or a mix of all imaginable colors, have a light white background or a deep dark backing - the variety is endless.

Opals are a unique gemstone in every sense of the word, from their crystal structure made up of millions of tiny spheres to their transparent, translucent or opaque bodies. The fascinating play-of-color in which a rainbow of hues dances before your eyes is one of the true wonders of nature. Opals are thought of by many as the most beautiful and exciting of all gemstones.
