These emerald stone engagement rings (mostly with diamonds, of course!) would make anyone not wearing them green with envy. Emerald engagement rings are perfect for anyone who wants something a little less conventional, with brilliant colour. The forest-green shade of this magnificent stone is truly remarkable. Below you'll find show-stopping emerald engagement ring styles from the crème de la crème of the jewellery industry. (Oh, and we've thrown in some green tourmaline pieces, too – a precious stone whose sea-green colour is just as striking.) If you don't know what ring to choose, you might find the answer right here. Either way, a special ring for a very special lady!
