Auction Format

Rapaport conducts Melee and Single Stone Auctions in a similar format to silent auctions and tenders, with viewing held over a five to eight day period at Rapaport diamond trading centers. Sealed bids are submitted by the close of auction and once closed, sellers have one business day to approve or reject top bids. Winning bidders are invoiced and have three business days to make payment. There are no buyer fees or premiums for participation.
