AUSTRALIAN PARTI SAPPHIRE - 1.45CT

A captivating Australian parti sapphire displaying a dramatic natural colour shift across its body — warm golden yellow at the crown transitioning through olive into a vivid teal and deep blue-green at the edges. This is quintessentially Australian: a stone that could only have formed in the basalt deposits of Queensland, where unique trace element concentrations create colour zoning that cannot be replicated anywhere else on earth.

Cut in a classic oval brilliant, the proportions at 7.5 × 5.4mm allow the full spectrum of colour to be appreciated face-up, with the yellow-to-teal gradient reading beautifully in natural light and the deeper blue-green tones emerging under incandescent light.

Entirely unheated and untreated — the colour is natural, permanent, and wholly the earth's own work. At 1.40 carats this stone is a strong candidate for a solitaire engagement ring, a three-stone setting, or a bespoke creation where the stone itself tells the story.

Available for private consultation and custom setting.
