- Play-of-Color: The most distinctive feature of opal is its play-of-color, an optical phenomenon where the stone displays flashes of different colors as it is viewed from different angles. This effect is caused by the diffraction of light within the silica spheres that make up the stone.

- Fire Opal: Known for its vibrant orange, yellow, or red body color, which may or may not show play-of-color.
- Boulder Opal: Contains veins of opal within a matrix of ironstone.
