Lumis Cushion Cut Diamond Ring
Payment Options
At the centre of the Lumis Ring sits a 2.09ct Cushion cut C4 VS1 champagne diamond, its soft geometry held against a hand-carved band of 18kt yellow gold. Thirteen round white diamonds scatter across one shoulder, a constellation of light against the ring’s organic, matte surface.
Lumis embraces irregularity. The gold feels almost geological, as though shaped by heat and pressure rather than polished into perfection. A champagne diamond ring where precision meets something altogether wilder.
Handcrafted in our Collingwood, Melbourne workshop from 100% recycled refined 18kt yellow gold and natural diamonds.
