This design centres on a 3.74ct emerald-cut Madagascan blue-green sapphire, the stone shifting between blue and green from every angle. The emerald cut features step-like facets that accentuate the gemstone's clarity and create a mirrored visual effect.

Complementing the centre sapphire are two baguette-cut 0.57ct white diamonds with F-G colour grading and VSI clarity, set in tab-claw and bar settings either side of the centre stone. The 2.5mm gold band with a high-polished finish carries the trio in a single horizontal line, the architectural cuts chosen so the ring reads as a clean three-stone composition rather than a centre with halo. As a green sapphire engagement ring built at scale, the Oasis is a bold emerald-cut composition.

Handcrafted in our Collingwood Melbourne studio from 100% recycled gold and ethically sourced stones.

Size Guide

We want your Black Finch piece to feel perfect from the moment it’s worn. Each ring includes a complimentary resize, which can be redeemed at a later date, giving you peace of mind if you're gifting or ordering online.

If you are unsure of your ring size at the time of ordering, please select the option for a free ring sizer tool to be mailed to you. We will hold the production of your piece until size is confirmed.

Most rings can be resized up or down by two sizes; for adjustments beyond this, our production team will assess the design and advise accordingly.
