Past, Present, and Future
The most common meaning of a trilogy ring is the 'past, present, and future'. That's why the trilogy is such a beloved engagement ring. Especially three-stone rings with a larger center stone reflect this really well. Three stones represent the different stages of the two of you.
Just as your engagement and wedding rings have similar yet unique meanings – your engagement ring for promise, your wedding ring for commitment – an eternity ring symbolises your everlasting love and devotion to your spouse.
