The paraiba tourmaline is one of the rarest stones on the planet and takes centre stage in this exclusive Marie design. This precious jewel is 100,000 times more rare than a diamond. The Marie's 1.86ct oval paraiba is the paraiba colour you should be looking for - almost a neon soft blue. It has 80 surrounding diamonds with a total weight of 0.56ct. Set in platinum, its wearer will feel like a queen.
