4.00 carats Natural Australian Black Opal | Freeform – 8 × 20 × 5mm

A striking Australian black opal displaying vivid blue-green flashes across a deep body tone. The contrast between dark base color and electric play-of-color creates strong visual intensity.

The elongated freeform shape allows the color bands to stretch naturally across the surface, producing movement under shifting light. The polish supports a smooth dome that enhances its optical depth.

With its slender proportions and dynamic color, this gemstone is well suited for pendants or protective statement rings where its play-of-color can remain the focal point.

This gemstone may be secured on its own, or crafted into a custom ring or fine jewelry piece through the SARATTI atelier.
