Question on Cartier Love Bracelet, what is the difference between the ones made today and the one made in 1970? In 1970, it was available in both solid 18k gold AND electroplate correct?? But any other differences such as shape? I can't quite tell but the ones today looks more oval (shaped to your wrist) and the older ones look like perfect circles. Anyone know? thanks! Also, is the rose gold and yellow gold same price today?
