In a video uploaded to YouTube, the Jersey Shore star touted the release of jeweller Diamond Shark's 'Snooki Party Ball 2011 Limited Edition Pendant'.
The pendant, which is adorned by pink sapphires, is fashioned after the necklace that Snooki wore while riding in an oversized New Year's Eve ball last Friday night.
The star urged her fans: "Make sure you come and pick it up because you know what, it's friggin' awesome."
The limited edition item is priced at $49 (£31).
Snooki's series Jersey Shore returns for a third season on January 6 on MTV.
