Australian Sapphire 16.60 × 12.00 × 6.30 mm Oval Dark Blue — 10.21 cts

An extraordinary Australian sapphire of exceptional size, displaying a deep dark blue body colour with subtle flashes of teal and green visible across the stone under changing angles. The substantial oval cut reveals broad areas of colour zoning and depth, creating the distinctive character for which fine Australian sapphires are renowned.

At 10.21 carats, this sapphire possesses remarkable presence, combining impressive scale with the rich, velvety tones highly sought in larger Australian material. Face-up, the gemstone exhibits a dramatic interplay between deep blue saturation and cooler blue-green reflections, contributing to its unique visual identity.

Originating from Australia, this sapphire represents a rare and commanding example of large Australian material — valued for its individuality, distinctive colour behaviour, and suitability for truly exceptional bespoke jewellery or collection.
