18ct White Gold Tanzanite Diamond Oval Cut Ring RW-0715-TZ The Tanzanite collection by Tivon showcases one of the world's most desired stones that is considered a thousand times rarer than the diamond. This seductive gemstone can exhibit a variety of surreal colours including blues, violets and burgundies so each piece is truly unique and beautiful. This exquisite and striking ring is a true statement piece that will distract every passer-by. It boasts a large oval cut tanzanite stone on a classic white gold band. Surrounding the stone in two rows, cascading onto the split shoulders of the ring is a stunning arrangement of brilliant and emerald cut diamonds which add a further dazzle of sparkle. This glittering dress ring would go perfectly with some of the other Tanzanite jewellery we feature on our website
