VALUES AND/OR APPRAISALS STATED IN AUCTIONS?
A value or an appraisal is an opinion and not the cheapest price guarantee. This is especially true with jewelry appraisals.  Appraisals issued with the jewelry are for insurance purposes and the actual retail value is usually MUCH lower, wholesale of mass produced jewelry is usually 10 to 20 percent of retail value so it has very large mark up prices in stores.  The insurance wants to know what it would cost to DUPLICATE the item in order to replace it exactly and this would involve someone custom making the piece and you can expect to pay a lot more then the retail amount to have this done.
MSRP (Manufactures suggested retail price) is exactly what is says, it’s the price the manufactures suggests that the retail outlets sell the item for.  It does not mean someone will not sell it for less and advertise that sale price.  Please research your items BEFORE placing a bid, if you can find the item for less somewhere else that just means you have done your homework better then the person currently holding the winning bid.
