THE PATIALA NECKLACE - One of the grandest pieces ever made by Cartier was the Patiala necklace. In 1926, Cartier received a trunk full of precious stones and jewelery belonging to Maharaja Bhupinder Singh of Patiala, who wanted his stones remounted in Parisian style. What was born is now famous the world over: The Patiala necklace, comprising 5 magnificent platinum chains, a cascade of 7 large diamonds, the celebrated yellow De Beers diamond, a tobacco-colored diamond and 2 rubies.
