I don't put much stock on "appraisals" provided by retailers, but I was looking at some paperwork and noticed that all the jewelry we have purchased on cruises (I think) have been appraised for the exact purchase price. When we have bought jewelry locally the retailers that have provided an appraisal typically appraise it higher than the purchase price - I guess to indicate what a bargain they gave us. Of course local retailers often want to sell me an appraisal, I decline because and go independent.
