Composition: Opal is composed of hydrated silica, often containing small amounts of water. Its distinct play-of-color is caused by the refraction and diffraction of light passing through tiny silica spheres within the gemstone.

Varieties: Opal comes in several varieties, including precious opal, which displays play-of-color, and common opal, which lacks this iridescence. Precious opal can further be categorized into types such as white opal, black opal, boulder opal, and fire opal, each with its unique characteristics.

Play-of-Color: The most distinctive feature of opal is its play-of-color, which can include a wide range of hues such as red, orange, yellow, green, blue, and violet. This phenomenon is caused by the diffraction of light as it interacts with the opal's internal structure.
