Sorry, I don't really "preach" (at least unsolicited) because people don't generally like being preached to and this is a topic that is incredibly emotional for some people for some reason.

The idea someone would worry replacing expensive trinkets with cheaper but similar looking trinkets might damage your marriage is extremely foreign to me! I can say that much at least!

Plus I don't know many impressionable young women these days because I'm approaching 40 and the majority of my friends are already married or no longer impressionable. :)
