White Opal Cabochon Value Guide

White Opal Cabochons are prized for their milky body tone and the mesmerizing 'play-of-color' that reflects a spectrum of light. These hydrated silica gemstones became a staple of fine jewelry in the 19th century, particularly as Australian mines began producing high-quality specimens for Victorian lapidaries.

What Is White Opal Cabochon Worth?

The typical price range for White Opal Cabochon is $20 - $150 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The intensity and variety of colors visible in the play-of-color significantly drive the $20-$150 price range.
• The pattern of the color flashes, such as pinfire or broad flash, affects desirability and market value.
• The quality of the cabochon cut, including symmetry and the height of the dome, impacts the stone's brilliance.
• Clarity and the absence of visible inclusions or sand within the white body tone increase the gem's worth.

How to Identify White Opal Cabochon?

• Look for a milky or translucent white body color that serves as the backdrop for iridescent flashes.
• Examine the 'play-of-color' under direct light to ensure the flashes move and change as the stone is rotated.
• Check the base of the cabochon for natural host rock or potch, which often indicates an authentic Australian origin.
• Verify the smooth, domed surface is free of cracks or 'crazing' which can occur in dehydrated specimens.

History of White Opal Cabochon

Opal has been prized for millennia; Romans called it a gem combining the beauty of other gems. Modern opal cutting into smooth cabochons became common in the 19th century as miners and lapidaries in Australia and Europe produced stones to show opal’s distinctive play-of-color. White opal from Australia and other deposits has been used in jewelry from Victorian times through today.
