harlequin opal
Noun: A variety of opal characterized by its reddish body color and distinctive small, bright, and often multi-colored patches or flashes that resemble the checkered costume of a harlequin.
This term is used specifically in gemology and mineralogy to describe a particular type of precious opal. It refers to the visual pattern and color of the gemstone, not its chemical composition.
- The jeweler showed me a stunning harlequin opal set in a pendant.
- Harlequin opal is prized for its unique play-of-color pattern.
- Of all the opals in the collection, the harlequin opal was the most vibrant.
The "harlequin" pattern is considered one of the most desirable and valuable patterns in opal. The term is often used in expert appraisals and high-end gem descriptions. - The auction catalog described the centerpiece as a "fine example of harlequin opal with a dominant red and green flash."
- Harlequin pattern (n): The specific checkered or mosaic-like arrangement of color patches seen in some opals and other materials.
- Precious opal (n): The broader category of opal that displays play-of-color, which includes harlequin opal.
- Fire opal (Note: This is a close but not perfect synonym. Fire opal typically refers to opals with a warm body color (yellow, orange, red) that may or may not exhibit play-of-color. A harlequin opal is a fire opal the specific harlequin pattern.)
The definition hinges on two key features: 1. A reddish base or body color. 2. A distinct "play-of-color" pattern where the bright spectral colors appear in small, angular, closely set patches, creating a mosaic or checkered effect reminiscent of a harlequin's costume. Without this specific pattern, an opal would not be termed a harlequin opal.
