In the world of Opals, the Harlequin Opal is the one stone that collectors wish they could find. This is an extremely rare pattern. Some stones may contain just a small part of the opal in this pattern but the pattern needs to encase the whole stone not just one part in order to be called a true Harlequin Opal.
A true Harlequin pattern is a repeating pattern of contracting diamonds or elongated squares.
The word Harlequin was a French word used in the 16th century to describe the comedian in an opera play of commedia dell’arte. This character used to wear an outfit with irregular shapes in bight colors.
