Australian parti-colour sapphire rings with unique blue-green hues.

Parti Sapphire Engagement Rings

This 3.65ct marquise sapphire comes from Australian sapphire country and shows the typical, practical character of those deposits. Colour is parti — a clear split between green and golden-pink zones — that shifts depending on angle and light. Under cool daylight the green component reads stronger; under warm indoor light the pink-gold warms up and becomes more apparent. Clarity is VS: small, pinpoint inclusions under 10x, nothing that distracts to the naked eye. The marquise cut gives strong length and presence, with crisp faceting that throws light along the stone’s axis. Expect a modest bow‑tie; orienting the stone correctly in the head will minimise it and maximise face-up colour. Practical jeweller notes: the pointed ends need protection — use V-shaped prongs or a partial bezel to avoid knocks. Two-tone settings work well here; 18ct yellow or rose gold brings out the warm party tone, while platinum/white gold will emphasise the green. Suitable for a bold engagement ring, a solitaire pendant or a signature cocktail ring where the length can be shown off without excessive setting depth.
