There is always a history behind something. The same holds true for the engagement ring worn by Kate Middleton. How old is the ring? How far back does the history of it go? Who wore the ring first?
Although the ring is only a few decades old, it still holds a rich family history behind it. It has great value as do other rings but this one more because of its roots to The Royal Family.
Although the ring in question is only a few decades old itself, its origin goes back a few centuries.
