This stunning cushion-cut Australian green diamond in a soft, earthy celadon hue is as understated as it is extraordinary. Natural green diamonds are among the rarest  on earth, and this pale, organic tone speaks to its uniquely Australian origin. Set in a handcrafted 22k gold square bezel, the stone is grounded in our signature gold work before meeting its most unexpected pairing: a polished, translucent antique cow horn band. Warm, sculptural, and entirely one of a kind, this piece sits at the intersection of fine jewelry and wearable art.
