There could be no better venue to properly fête a Parisian brand in New York than La Grenouille.

Last week, Moda Operandi and Mazarin Co-Founders Louise de Rothschild and Keagan Ramsamy gathered a flock of fashion favorites to celebrate the brilliant fine jewelry brand's new launch.

Their debut collection, which features lab-grown diamonds and recycled gold, was on parade throughout the evening, with everyone from Beverly Nguyen and AnnaSophia Robb to Minnie Mills and Pat Cleveland modeling their favorite pieces.

Upper East Side icon Earl Rose took a night off from his usual post at Bemelmans, pulling up a chair at the piano to set the sophisticated scene during cocktail hour. A delicious dinner of French classics followed in the restaurant's divinely decorated second floor perch.

So, curious to see who wore what?
