Rapaport Price List – “The Benchmark Price Guide and Industry Standard” Who and What is Rapaport? The Rapaport Group is an international network of companies providing first class, added value services to the diamond and jewelry markets. Established in 1976, the Group has over ten thousand clients in 70 countries. The Group was started by Martin Rapaport. A genius with an economics background, he grew up in a diamond family and rose to fame by reporting wholesale diamond prices during the 1979-80 commodity boom. At this time the Rapaport Price list was born, and the group was the first to run a business-to-business electronic diamond price-comparison service. At its simplest level the price list is used by buyers and sellers as a price list of market values for various sizes colors and clarity qualities. In the past 30 years this list has progressively become the international benchmark pricing standard for the diamond industry. Their online portal is populated daily with over 525,000 diamonds valued at $4.12 Billion dollars. Across all Global Diamond Markets, Diamond business agreements and dealer sales are now based on Rap or List prices .

Slide 14: 

Who and What is Rapaport Continued… How Rap Works? The Price Lists quote the Rapaport opinion of high cash asking prices for Diamonds. Actual transaction prices may be at a discount or premium to the Rapaport Lists. The level of discount or premium varies greatly and is influenced by many factors. Stone quality and cut, credit/memo terms, the location and type of market and the liquidity level of particular size/quality combinations all impact the discount level. Liquidity and the associated risk of ownership are also a factor, The final achieved ‘ discounts to Rap ’ is the product of a combination of many factors employed leading up to and during the point of purchase. We aim to consistently beat the Rap when purchasing for our clients.
