About Harlequin Opal

Harlequin opal is considered the most prized pattern variety of precious opal, displaying a closely mosaic-like arrangement of vivid, broad color patches in red, green, blue, and gold that resemble the diamond-patterned costume of a harlequin. These highly regular, large-patch color patterns are exceptionally rare and command the highest prices among opal collectors and connoisseurs. The finest examples originate from Lightning Ridge and Coober Pedy in Australia, and specimens with genuine harlequin patterning are among the most valuable opals in existence.
