It was started by ancient Egyptians since they believed that a circular ring is perfect to define an everlasting relationship between a couple. As circular bands do not have an end or a beginning, they are perfect to symbolize a never-ending bond.   At the very beginning, engagement rings were made using iron. Later, the supreme gold metal took over the industry. However, engaged women used to wear an iron ring at home and a gold ring while going out. When it comes to the history of diamond rings, the inclusion of precious stones in the engagement rings began after the discovery of diamond mines in South Africa. The first diamond engagement ring to be recorded in the history books is the one that was gifted by Archduke Maximilian of Austria to his ladylove, Mary of Burgundy, in 1477. It was a huge gold ring that featured a big ‘M’ made using tiny diamonds. Maximilian made that ring in order to ask her hand for marriage, and the tradition of gifting diamond rings for proposal followed. At first, only wealthy people were able to flaunt diamond rings. Nevertheless, things have changed later with the invention of diamond mines in different parts of the world, and today, everyone can buy a diamond ring.
