Launched in 1978 by the founder of the Rapaport Group, Martin Rapaport, the Rapaport Report – or the Rapaport Price list as it is widely known – is the international benchmark used to establish diamond prices in all the major markets.
The Rapaport Price list is updated weekly on Thursdays and published weekly. It provides jewelers and diamond merchants with the standard pricing for consumers. The report prices diamonds according to the 4Cs of diamonds - carat, color, clarity and cut. The list, which is only provided to subscribers, reflects changes in the global diamond markets.
