Cushion-cut sapphire sits within milgrain-edged bezel surrounded by diamond halo creating brilliant frame.

Gallery exhibits openwork construction allowing maximum light entry while maintaining structural integrity. The mounting represents quintessential Art Deco aesthetic with symmetrical design and decorative elaboration.
About The Sapphire
This 4.02 carat Ceylon sapphire exhibits rich royal blue color with exceptional transparency and cushion cut proportions. No-heat treatment designation confirms the stone's natural color without thermal enhancement, significantly increasing value and desirability. Dual certification from Gubelin and AGL, two of the world's most respected gemological laboratories, provides comprehensive authentication and quality documentation. Ceylon sapphires from Sri Lanka remain among the most prized colored gemstones for their superior color saturation and transparency.
Large gem-quality sapphires like this are rarely found in nature—formation requires precise geological conditions, adequate pressure and temperature, and a rare combination of chemical elements including aluminum, iron, and titanium.
Most sapphires on the market are heated to improve color and clarity. This one wasn't. What you see is exactly what nature produced.
Demand for unheated sapphires continues to rise while supply from major sources—Kashmir, Burma, Sri Lanka, Madagascar, Tanzania—remains limited. Stones like this are increasingly difficult to source.
