You Have to See How Big This Cartier Diamond Ring Is

It's almost officially holiday season, which means engagement season is also nearly upon us. To tie both those worlds together, Cartier teamed up with supermodel Karen Elson for its latest holiday video campaign—but the film's true shining star is the gigantic diamond ring Elson models.

Elson puts on the enormous ring—comprising a multi-karat round-cut diamond atop a baguette diamond band with triangular pavé diamond accents—then proceeds to take Paris by storm, emboldened by her newly acquired gemstone powers. Elson also lent her vocal prowess to the clip, belting the classic Marilyn Monroe song "Diamonds Are a Girl's Best Friend."
