2.41 ct Unheated Australian Blue Sapphire - GIA Certified

Classic Shape - Cushion Sugarloaf Cabochon

This distinctive natural sapphire from Australia weighs 2.41 carats and has been shaped into a beautifully sculptural cushion shape sugarloaf cabochon. Its softly rounded square outline and high-domed profile give the stone a strong visual presence while allowing its deep blue color to remain the focal point.

The sapphire is described by GIA as transparent blue natural corundum, with an Australian geographic origin. Most importantly, the report states no indications of heating—an increasingly meaningful distinction in a market where many sapphires are routinely heat treated to improve their color or clarity.

At 7.33 × 7.28 × 4.56 mm, the stone has balanced proportions and an appealing square shape. Its sugarloaf cut gives it a smooth, architectural quality that would work beautifully in a custom ring or pendant, while also making it an interesting standalone addition to a gemstone collection.
