Engagement Rings as Family Heirlooms

Oh my gosh! I have never seen a hand engraved engagement ring before but I just saw some online when I was doing a search for engagement rings orange county. These are the kind of rings that become definitely become family heirlooms! I thought the price would be beyond affordable but they're not. It's about the average price paid I think.

I love the idea of passing my wedding set down to a daughter to wear. The problem is how do you do that when you have more than one? I have several nice pieces so I can divvy it all up somehow but the wedding set is the most important one. I don't want my kids to think it is playing favorites.
