Our new bridal & milestone collection MARINE takes its cues from the elegance and strength of ocean kelp.
Each ring is sculpted in 18-karat solid gold around a hand-selected stone - sapphire, natural diamond or peridot - chosen for its unique cut, colour and character. The setting is shaped in response to the stone, following its natural line to create our signature golden kelp design.
Each piece is made to order and handcrafted in our Sydney studio. We warmly invite you to book a private consultation, either virtually or in one of our flagship stores.
Unearthing Origins
Behind the Design
MARINE blends innovative design technology with traditional craftsmanship. Creative Director Sarah Gittoes takes us through the design process, where each piece is refined by skilled hands at every stage.
LOVE IN FULL COLOUR
At the heart of our MARINE collection is a celebration of life's most vibrant connections. Alongside natural diamonds, we’ve chosen coloured gemstones, including Australian sapphires and peridots, to capture the depth and richness of love.
Each gemstone is hand-picked for its unique character, cut, and colour, reflecting the individuality of your relationship. Like the ocean kelp that inspired the collection, these stones are radiant in their beauty and deeply connected to their origins.
