Promise rings have been a part of the process of commitment of marriages and betrothals for hundreds of years. Originally promise rings were given to signify that an understanding had been made between two families. The giving of the promise ring was a symbol that the couple were promised to each other, the families had agreed, and at some stage, the happy couple were bound to be wed.

Promise rings have been known by various names throughout history. In the 16th and 17th Centuries, rings were given between lovers and became known as "scribbling rings". These rings symbolized love, and the uncut diamonds set in these rings were used to etch romantic poetry into window panes or mirrors.

Speaking of poetry, another popular form of promise ring was the "poesy ring" , or love poem ring, which had romantic sayings or lines from poems engraved upon them. These were well used in the 17th Century in both France and England.

What is a modern promise ring? In recent times promise rings are seen as a sign of a commitment. Generally, this can often be a commitment or promise between a couple who are not yet engaged. Promise rings are usually less costly than an engagement ring and often feature heart settings or heart shaped stones. Colorful gems are often used instead of diamonds, to keep the rings more cost effective, and also to look less like an engagement ring.

A promise ring poem can be engraved on the outer or inner side of the band. Popular inscriptions can be derived from Latin, Italian, Spanish, French, Irish, or Old English sayings. Excerpts from songs or religious statements can also be used. Popular promise ring inscriptions include " My Beloved", "Vous et nul Autre" which translates to "You and no Other", "Yours Only", "Of my Love be Sure" and "Anam Cara" which translates to "Soul Friend".

Promise rings can also be engraved with ancient symbols, and Celtic knots and swirls, for extra embellishments and meanings.

Promise rings are generally made in more affordable metals such as sterling silver or gold.
