Engagement ring bearer w marquee cut ring size 5

Perhaps the perfect design. Marquee shaped 24k gold and when flipped, a plain band. Eliminate the need to add a stone. Eliminate the need to buy a separate band. Exactly shaped for comfort when flipped. Mechanical ring bearer walks. Fun novelty. You have to ' break ' ( please don't actually break the ring bearer, it is a take apart design ) the heart and put it back together to get the ring. Just checked all mech parts for proper function.
