GUIDE TO THE
T
he Rapaport Price List is commonly used by dealers
as a guideline for evaluating natural diamond prices.
Readers should understand the List’s standards for
describing diamonds, as well as its limitations and
how it can be used to aid buyers and sellers.
The Round and Pear Shape Price Lists are published online
every month.
H I GH ASK I NG PR I CE S
The Price List quotes Rapaport opinion of high cash asking
prices for Rapaport Diamond Specification A3 and better
natural diamonds. These prices may be substantially higher
than actual transaction prices. It is most common for the
diamond trade to transact at discounts to the List. However,
select quantities that are in short supply or subject to
speculative demand may trade at significant premiums
to the List.
Detailed information about discounts is provided online
in real time via our RapNet® and RapX® diamond trading
networks. They are also included in the Trade Sheets published
in this magazine.
The level of discount or premium is influenced by many
factors, including diamond quality and cut, credit/memo terms,
the location and type of market, the liquidity level of particular
size-quality combinations, and the associated risk of ownership.
The easier it is to sell a diamond, the lower its discount to the
List. Hard-to-sell diamonds often trade at large discounts. Very
in-demand, scarce diamonds may trade at premiums.
