The Rapaport Price List is a weekly list of polished diamond prices. It quotes Rapaport's opinion of high cash asking prices, not transaction prices.
In more detail
Rapaport publishes a Round list and a Pear Shape list, which also covers other common shapes. For better qualities, the list relates to diamonds with GIA grading reports. Dealers use it as an approximate guideline and a starting point for negotiation. Dealer trades tend to settle at a discount to the list.
