This is a Helga Hufflepuff’s stunt Horcrux cup used in the film, Harry Potter and the Deathly Hallows Part 2. Helga Hufflepuff’s Cup was a magical item created by one of the founders of Hogwarts School of Witchcraft and Wizardry, Helga Hufflepuff. It was a small golden cup with two finely-wrought handles with a badger engraved on the side and a few jewels. The badger is the symbol of Hufflepuff House. The cup also has the dubious distinction of being the only object known to have been stolen from a vault (specifically the vault of the Lestrange family) at Gringotts Wizarding Bank.
