This emerald Maharani necklace by Nirav Modi combines graduated, rare, vivid green emerald beads - a total of more than 870 carats - in a one-of-a-kind jewel that channels the opulent maharajah necklaces worn by Indian royals in the 19th and early 20th century. Complemented with 146 carats of oval- and pear-shaped diamonds, the emeralds in this majestic necklace have been painstakingly sourced by Modi over many years to ensure perfect symmetry.
