Today, the engagement ring is almost universally associated with the promise of marriage, often imagined as a diamond set in gold and presented during a carefully staged proposal. Yet the custom of giving a ring to mark a betrothal has much older roots, and some of the earliest clear evidence for the practice in the Western world comes from ancient Rome.
In Roman society, marriage was not only a personal union but also a legal and social agreement between families. The engagement, known as sponsalia, formalized the intention to marry and was often accompanied by the exchange of gifts; among them, one was a ring given by the future husband to the bride-to-be, symbolizing the commitment that had been made.
