Engagement and wedding rings with initials

Engagement rings are a well-established custom given by a boyfriend to his girlfriend when they decide to marry. But did you know that this custom actually dates back to ancient Roman times?
In modern times, technology for engraving initials and letters has advanced, and the variety of expensive precious metals has increased, including not only gold, silver, copper, and diamonds, but also platinum and tungsten, but anciently they were made of iron. In the 2nd century they were replaced by gold, and in the 5th century the custom of wearing wedding rings on fingers after marriage apparently began. Wedding rings began to be incorporated into marriage ceremonies around the 11th century, so it is a custom with a long history worldwide.

Nowadays, engagement rings given by men to women are typically adorned with diamonds or birthstones. Perhaps because wedding rings are intended to be worn daily by men, simple, timeless designs are becoming increasingly popular. Gold and platinum are the most common materials, and initials and commemorative letters are typically engraved on the flat inside. Incidentally, the oldest engagement ring adorned with diamonds is said to be the one worn at the wedding of the Holy Roman Emperor of the Holy Roman Empire, a major empire in medieval Europe, which is quite an interesting story.
