About the Stones:
This GIA-certified 8.69 carat black opal is confirmed to have received no color treatment, making its vivid blue, violet, and teal play-of-color entirely natural — an exceptionally rare quality in a stone of this size. The oval cabochon cut maximizes the opal's color surface, allowing the rolling flashes of electric blue and cyan to shift dramatically with every movement. Surrounding the opal, 1.78 carats of tapered baguette diamonds in F–G color and VS clarity create a sparkling frame that amplifies the opal's depth and mystery. Black opals of this caliber with GIA no-treatment documentation are among the most collectible and investment-worthy gems in the fine jewelry market.
