Chanel hosted a dinner party coinciding with Paris Fashion Week. French actress Marion Cotillard arrived and remarked that it felt “right to celebrate this icon with something that is almost eternal,” like diamonds, according to WWD.

Cotillard wore a 10ct emerald cut diamond necklace that mimiced like drops of rain. 

The N 5 collection is a mélange of 123 pieces. The standout piece in the collection is the 55.55 necklace that mimics the profile of the perfume bottle stopper and the bottle’s shape, before spilling into a cascade of pear-shaped diamonds of varying sizes.
