Cardi B bought herself an ultra-rare pink “Barbie” Rolex Cosmograph Daytona for $2.85 million, insisting on a factory-original watch authenticated by Rolex.

The 18-karat gold Daytona features 36 pink sapphires, diamond accents and a pink alligator strap, and jeweler Eric Mavani estimates only about 10 exist worldwide.

She also picked up a custom 7-carat diamond ring and a pink Hermès Mini Kelly, bringing her self-gifted birthday haul to roughly $4 million.

Cardi B took her ice to a new level with her latest birthday gift to herself.

On Oct. 22, the rapper posted an Instagram video of jeweler Eric Mavani handing over an ultra-rare pink "Barbie" Rolex Cosmograph Daytona.

"From Belcalis to Cardi B…a gift from me to me!!" she wrote in the caption, thanking Mavani "for searching all around the world and finding me this watch, authenticated by Rolex!"
