Opal Cabochon Value Guide

This 2.0 carat Australian Black Opal cabochon from 1988 represents a classic example of the world's most coveted opal variety. Its value lies in the unique play-of-color created by light diffracting through microscopic silica spheres, a hallmark of high-quality Australian specimens.

What Is Opal Cabochon Worth?

The typical price range for Opal Cabochon is $300 - $360 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 the play-of-color across the 2.0 carat surface.
• The darkness of the body tone, which enhances the brilliance of the internal flashes.
• The physical condition of the cabochon, specifically the absence of surface crazing or scratches.
• The historical provenance of the 1988 Australian origin and original protective packaging.

How to Identify Opal Cabochon?

• Verify the 2.0 carat weight and oval cabochon cut consistent with 1980s Australian lapidary standards.
• Examine the stone for a dark body tone characteristic of authentic Black Opal origins.
• Check for a natural, multi-directional play-of-color rather than a repetitive pattern found in synthetic stones.
• Inspect the vintage 1988 protective coin flip holder with metal staples for period-accurate provenance.

History of Opal Cabochon

Opals have fascinated humanity for millennia, revered for their unique play-of-color. Ancient Romans considered them symbols of hope and purity, while Bedouins believed opals fell from the sky during thunderstorms. The most celebrated opals, especially black opals, often originate from Australia, where they were first discovered in commercial quantities in the late 19th century, leading to a global opal rush. The distinctive 'play-of-color' in opals is caused by the diffraction of light through microscopic silica spheres within the stone.
