Having cost her fiancé a cool $7million, it's the only accessory she needs.
But Mariah Carey nearly outshone her flashy engagement ring when she arrived to 1 OAK nightclub for a wrap party in honour of the end of winter residency in Las Vegas on Saturday night.
The 45-year-old looked like a million bucks in her plunging silver mini dress and a pair of Christian Louboutin heels to match.
The songbird was more than happy to show her brand new ring, however, which was given to her by her billionaire fiancé James Packer.
The businessman popped the question to Mariah last month in New York, however he did not appear to join his lady love for a night out in Sin City.
