One is set at the Musée Rodin (a must for your next trip to Paris), the second in an elevator at the Philharmonic Concert Hall and the last at the airport. The unifying link? Each proposal is marked by - you guessed it - a precious red box containing a Cartier diamond ring.

The film, directed by Academy Award-nominee Sean Ellis with a screenplay by French writer Olivier Lecot, is a beautiful tribute to love and a gorgeous showcase for three Cartier diamond rings. See the entire film above, or visit YouTube to watch each proposal on its own - then forward your favourite to your boyfriend if he needs a nudge. Accidentally, of course.
