On Thursday evening, Tiffany & Co. and HardWear campaign star Anna Weyant cohosted an intimate dinner celebration at The Landmark on Fifth Avenue.

 ”I’ve never done anything like this before, so I was pretty nervous and intimidated,” Weyant said from the flagship’s eighth floor terrace. The artist stars in the line’s spring campaign, which celebrates love and strength, with Mikey Madison and Greta Lee. “But it was great. Everyone made it easy, and it was awesome company with Mikey and Greta. It was a really big honor.”

Weyant was decked out in a set of HardWear jewelry set, including the same necklace that she wears in the campaign photographed and directed by Harley Weir. But her familiarity with the Tiffany HardWear graduated link necklace in yellow gold with pavé diamonds runs deeper.

“So a few years ago I actually painted this exact necklace,” Weyant said. The painting, which predates the HardWear campaign, currently hangs in a private client salon on the fourth floor. “I feel like I know it so well. I know the light and I know the shadows, and I’ve spent so much time looking at it. And so then wearing it for the campaign was surreal and really cool,” she added. “ I paint a lot of jewelry, and so I’m always looking at Tiffany for inspiration.”

The artist is currently preparing for the opening of her next museum show, at the Thyssen-Bornemisza National Museum in Madrid, in July.

A long dinner table, adorned with calla lillies and Tiffany blue boxes at each place setting, greeted guests on the balmy terrace. Ruby Aldridge was on DJ duty during cocktail hour as guests including “I Know What You Did Last Summer” star Chase Sui Wonders, Laura Harrier, Phoebe Gates, Georgia Fowler, Karen Elson, San Francisco Ballet principal WanTing Zhao, Isabella Massenet and more caught up over cucumber margaritas and sunset views of Central Park South.
