Bidding Instructions

Auction Format

Rapaport Melee and Single Stone Auctions function in a silent auction format. The viewing of the diamonds in auction occurs over a set period of time. All sealed bids must be placed by the specified deadline to be counted for that auction. Once the auction closes, suppliers have one business day to approve or reject the highest bids. After that, buyers are invoiced for all lots accepted by the seller.
