I have a few questions and would love any advice 
My fiance purchased a Tacori engagement ring (as well as a wedding band) a while back. He saved up and was able to purchase a diamond this week (
). He bought the diamond online.
1. I would like to get the diamond appraised to make sure it is worth at least as much as he paid. Should I do this before I have it set or after (if I do it after, I'll have the total value for insurance reasons).
2. Second, we need to have the diamond set. Do you think we should have it sent back to Tacori to have it set? Or should we have it set by the store we purchased it from (Bailey, Banks, and Biddle)? Or should we have whoever appraises it set it (I would have it done by someone certified by the National Association of Jewelry Appraisals).
3. Another concern of mine is that whoever sets it could possibly switch the diamond. How can I guard against this happening?
I'm also having an issue with ring sizing... the salesperson who sold us the ring insisted I get a 4.5 when I told her that the size 5 felt more comfortable... she kept telling me that the ring sizer was off, etc. So we purchased both rings in a 4.5 and they are SO TIGHT. I can barely get them off. Just trying on my engagement today, I actually cut my knuckle trying to get it off. Should I discuss this with the store I bought it from? I shouldn't have listened to the salesperson -- I should have gone with my own instinct -- but I thought 'she's the expert, she knows what she's talking about'. I'm very concerned that it can't be resized.... and I'm frustrated that the salesperson pushed us into making such a big purchase in the wrong size.
I know I should have done something about this sooner but I'm afraid to bring it up to my fiance because the rings cost him so much money...
Thank you for any advice on any of my questions!!!
