Most Expensive Marie-Antionette Necklace

From the De Beers High-Jewellery collection, this luxurious necklace features over 181 carats of mixed cut diamonds. Beneath the deep pink diamond (1.84 carats) on the first string are two yellow diamonds (5.24 and 7.06) along the second and third strings. The 8.05 carat pear-shaped white diamond hanging from the fourth string, though, is the showstopper on this beautiful piece of jewelry
