18ct White gold Tanzanite and Diamond princess cut necklace. 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 simple but stunning necklace is a gorgeous piece that boasts a 1.04ct tanzanite stone that contrasts beautifully to the white gold it is set in. The delicate white gold chain is completed by a beautiful 0.07ct round brilliant cut diamond set into the bail for a touch of sparkle. This is a stunning and versatile necklace that can be worn as a striking everyday accessory or a subtle dress piece. This necklace would go perfectly with some of the other Tanzanite jewellery we feature on our website. 18ct White Gold, Tanzanite 1.04ct, Diamond 0.07ct.
