Thanks for all the advice and well wishes.
I have become quite knowledgable in diamonds in the last couple day and now know what to look for.

Although resale value is of no importance to me quality of a diamond is. A good quality diamond looks alot different then a poor one. As well as colour and cut can have a huge impact of the diamonds apperance.

Well.. looks like what I could do for sure is stirrup a lot of sand.(emotions).
I think the best is to be informed and make your own decision based on that.
My wife has a diamonds too, just because that what she wanted.
I see no value in diamonds,only have tiny one (gift from wife) my live rock have way better resale rate as well as other SW equipment compare to our furniture and TV. LOL !

The good thing is that we are having civilized discussion right ?

Wow, my girlfriend and I are both gun shy (gun = marriage) her a bit more than me, so after seeing this thread I'm really glad she's the smart one.... although with her standing over my shoulder she eloquently reminded me that diamonds are her birth stone and she'd still like one someday.... ewoops
