This lovely 9 carat White Gold Cubic Zirconia Knot Pendant has a matching pair of earrings: wear the set together for some really harmonious contemporary chic or wear the necklace separately to bring your ensemble together perfectly. Thanks to its toned-down modern design this knot pendant will make the most of casual outfits or bring a classic elegance to business wear. Cubic zirconia is the manmade equivalent of a diamond with none of the ‘inclusions’ or flaws which occur in natural gemstones: cubic zirconia is created to be flawless and to have even more ‘fire’ than a diamond. Heavier than a diamond although not quite as hard cubic zirconia also has a fascinating history: developed by Soviet scientists in Moscow during the Cold War the gemstone has gone on to be mass-produced all over the world and is an affordable equivalent to a diamond in precious jewellery.
