Diamond Listing Websites (18.06)
Rapaport Diamond Report is highly recommended to subscribe to for any diamond dealer -- being the largest natural diamond database in the world. It is the opinion of the author that much of the list, not listings, is over estimating but it is still an excellent source to refer to on a regular basis. Using this publication along with reliable diamond dealer inventory lists and experience will give you a clear picture of current diamond values.
