The Equinox showcases a 3.26ct ethically sourced Australian teal sapphire, resembling the deep hues of twilight and the ever-changing phases of the moon, from waxing to waning. Encircled by a constellation of round brilliant white diamonds set using a traditional stone setting technique, the design pays homage to the mystique of the night sky.

This one-of-a-kind piece sets the centre teal sapphire flanked by white diamonds across a fine 2mm 18kt yellow gold band, the high-polished finish chosen so the deep tones of the sapphire read against the bright spark of the diamond halo. As a teal sapphire ring on a Black Finch one-off scale, the Equinox is the studio's most direct night-sky composition.

Designed and hand-finished in our Collingwood studio, in 100% recycled 18kt yellow gold and ethically sourced stones.
