“Diamonds only have to do one thing: return light,” said Frank Everett as he fastened a van Cleef and Arpels necklace for Margaret Russell, editor in chief of Architectural Digest. Russell stopped by the Sotheby’s penthouse at the 1 Hotel for reception for a Magnificent Jewels/Sotheby’s Diamonds hosted by Caroline Fitzgibbons, Susan Sandler, Frank, Gadi Behar and Everett. The necklaces were paired with evening gowns by Marc Jacobs but the diamond stunner that Russell tried on went perfectly with her slim black cocktail dress. Also among the fashionable crowd: models Kristina Tsirekidze and Maye Musk, Caspar Jopling, India Rose James, Yanis Axis and Natalie Galvez. – Meghan Dailey
