This is an 18ct white gold ring set with two brilliant cut diamonds and an oval green tourmaline. It's a really beautiful deep green colour with a hint of blue. The ring is designed with a sweeping setting that allows a wedding ring to set flush next to it without it having to be shaped. The tourmaline is 10.5mm by 7.5mm and weighs 2.24ct. The diamonds on either side are 3mm and weigh 0.10ct each giving a total diamond weight of 0.20ct.
