Tiffany & Co. held a cocktail event to launch its new Tiffany Hardwear collection in New York City, following the unveiling of the new jewellery pieces during Super Bowl LI this past Sunday -- with a halftime TVC that featured pop diva Lady Gaga.

With its bold 18k gold and sterling silver pieces, Tiffany HardWear was inspired by a unisex bracelet from 1971, found in the Tiffany Archives, with a new range that includes earrings, rings, necklaces and pendants.

Attending the exclusive event were Kate Mara, Karolina Kurkova , Rebecca Dayan, Hari Nef, Olivia Wilde, and Christina Ricci.
