Representing the aftermath of a meteoric collision; the 'Collision Ring' is crafted in 18 carat Single Mine Origin Yellow Gold and set with an exclusive Stellar cut Skydiamond (0.30ct). Designed to be worn as a signet ring. 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: WR1263 Unsure on your ring size, please use our ring sizer .
