White Opal Value Guide

Australian white opals are highly collectible for their distinctive milky body tone and the subtle, shifting play-of-color that has fascinated gem enthusiasts since the late 19th century. Originating from Australia's rich deposits, these 20th-21st century specimens carry a legacy that traces back to the Roman 'Opalus', once believed to possess mystical powers. This $500 polished gemstone represents a blend of ancient geological history and refined modern lapidary art.

What Is White Opal Worth?

The typical price range for White Opal is $500 - $500 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The vibrancy and range of the play-of-color are primary drivers for the $500 valuation.
• The absence of internal inclusions or 'potch' lines within the polished face increases the gemstone's market value.
• The symmetry of the cut and the quality of the final polish affect how light interacts with the stone's internal silica spheres.
• The overall carat weight and dimensions of the specimen significantly influence its final appraisal in the collectible market.

How to Identify White Opal?

• Examine the stone for a translucent to opaque milky white body color which is the hallmark of authentic Australian white opal.
• Observe the play-of-color to ensure flashes of light originate from within the gemstone's structure rather than being a surface application.
• Inspect the surface for a smooth, high-gloss polish and the absence of 'crazing' or fine hairline cracks.
• Verify the stone's solid nature to distinguish it from doublets or triplets which feature thin opal slices glued to a backing.

History of White Opal

Opal has been cherished for centuries, with its name believed to originate from the Sanskrit word 'Upala', meaning 'precious stone'. The Romans later adapted this to 'Opalus'. Ancient cultures often associated opals with mystical powers, believing they could bring good fortune and clarity. Roman naturalist Pliny the Elder famously described opal as combining the best qualities of other gemstones. Australia became the world's primary source of opals in the late 19th century, particularly white opals, which are known for their subtle play-of-color and milky body tone.
