Wholesale dealer’s price guides for diamonds.
The ISG Global Network Diamond Pricing Guides are a composite pricing table based on several industry price publications and additional research done in the ISG office. All are based on actual reported selling prices of wholesale diamonds in various world markets. It should be noted that prices of diamonds can vary greatly in the market based on many factors, and anyone seeking diamond price information should take into account the factors that may affect prices in your area that could cause prices to deviate significantly from the prices listed below. As a result, the ISG accepts no liability for any use of these price guides for anything other than a basic price reference chart to assist appraisers and buyers/sellers in making better informed decisions. Please see the individual lists for specific limiting conditions of the pricing guides.
