Simplicity and style collide with the 'Momentum Band Ring' crafted from 18 carat recycled Yellow Gold and set with an exclusive Volt cut Skydiamond (0.73ct). The Stephen Webster x Skydiamond collection is inspired by space and the sky, incorporating the world's first carbon negative, man-made diamond, mined from the sky . Using unique, patented technology, carbon is mined from the sky and fed into a lab, exhausting clean air back into the atmosphere – an innovative process that transmutes the air we pollute, into certified diamonds . Each cut is unique to Stephen Webster, offering contemporary range with a nod to alternative bridal jewellery. Style Code: WR1173 Unsure on your ring size, please use our ring sizer .
