Diamond industry standard wholesale price list. Most diamonds sell from diamond dealer to diamond dealer ( or dealer to jeweler) at the list price to about 35% discount to the list. Thus a diamond that lists for $10,000, the wholesale price is usually between $6,500-$10,000. AmericanBazar usually sells a diamond that list at $10,000 for $2,000- $6,000 , far below normal wholesale. ( see about us page for more info)
