The Aurelia
One fiery carat, round cut and set at the centre in eighteen-karat gold framing its brilliance. This piece carries a weight you can feel the moment it settles onto your finger, leaving a gentle warmth against your skin.
This signature piece never dulls; it’s jewellery made to last and age with you.
The stone pulls every scrap of light it can find with six and a half millimetres of D-colour clarity and scatters it back in flashes.
There's a tension in the pairing; soft metal, hard stone, warm tone against cold fire. Built without compromise, worn without question.
