The first person in the world to take the ring as an engagement token was King Maximini of Austria. 1477, Maximini met Princesse Marie. Maximina was fascinated by her beautiful appearance and elegant manners. But Mary was engaged to the crown prince of France at that time, but he still didn't give up. In order to win Mary's love, Maximini had a precious diamond ring made for Mary.
