Paris Hilton may have finally found her Prince Charming. Venture capitalist Carter Reum proposed to the heiress/entrepreneur over Valentine weekend with an emerald-cut diamond engagement ring fit for royalty.

The ring design by jeweler Jean Dousset — the great-great-grandson of famed French jeweler Louis Cartier — takes its inspiration from the architectural elements of the iconic Grand Palais, the exhibition hall and museum complex located at the Champs-Élysées.
