Color:

The color patches in a Harlequin Opal can exhibit a wide range of hues, including red, orange, yellow, green, blue, and violet. The vivid and contrasting colors contribute to the opal's overall beauty.

Play-of-Color:

Harlequin Opal, like all opals, displays play-of-color, which is the result of the diffraction of light as it passes through the microscopic silica spheres within the opal. This play-of-color creates the vibrant flashes and patterns that make opals so captivating.
