The screwdriver is also available in the form of a necklace, allowing the bracelet to be "locked" onto one person, while the "key" is kept around the neck of another, as a symbol for their commitment to their relationship . </P> <P> Cartier has offered the Love bracelet in 18k yellow gold, 18k "pink" (rose) gold, 18k white gold, and in platinum .
