 Dior Joaillerie, Soie Dior ‘Froufrou Rubis’ ring | It was long believed wearing a fine red Ruby bestowed good fortune. In the hierarchy of precious gems, the ruby has no peer: the Indians call rubies ratnaraj, the “king of precious stones”. Burmese stones, from the Mogok area, are rare and their growing scarcity has driven prices to record levels. Rubies continue to be a very good investment. |  Cartier, Resonances Bracelet |
 Graff, Ruby and Diamond Earrings | Mozambique rubies have emerged on the world stage over the past few years. Even so, larger sizes remain elusive.
