When one is just not enough, opt for the 'Polyamorous Ring' featuring four exclusive Volt cut Skydiamonds (0.99 total carat weight) and crafted in 18 carat recycled Yellow Gold. 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: WR1184 Unsure on your ring size, please use our ring sizer .
