In the world of diamonds, pricing transparency isn’t just important… it’s essential. Whether you’re a seasoned jeweler, diamond dealer, or new to the trade, understanding how diamonds are priced in the global market is critical to running a profitable and trustworthy business.
Enter the Rapaport Diamond Report… often referred to as the industry’s most influential pricing benchmark for loose diamonds. In this article, we’ll break down what the Rapaport Report is, how to read it, and why it remains a cornerstone of modern diamond trading.
What Is the Rapaport Diamond Report?
Founded in 1978 by Martin Rapaport, the Rapaport Diamond Report is a weekly publication that provides standardized pricing information for polished diamonds. It’s widely regarded as the go-to source for diamond price listings and is used by jewelers, traders, appraisers, and even financial institutions around the world.
The report doesn’t set prices… It reflects the current market values of diamonds based on size, shape, color, and clarity. Its purpose is to promote transparency and consistency in diamond pricing, particularly in the wholesale sector.
How to Read the Rapaport Report
At first glance, the Rapaport Report can seem overwhelming. But once you understand the layout, it becomes an indispensable tool.
Here’s how it works:
- Price Tables: The report is organized into price grids based on shape (primarily Round, Princess, etc.) and carat weight ranges (e.g., 0.30–0.39 ct, 1.00–1.49 ct, etc.).
- Color and Clarity Axis: Along the rows and columns, you’ll find diamond color grades (D–Z) and clarity grades (IF to I3).
- Price Listings: Inside the grid, the numbers represent the price per carat in hundreds of U.S. dollars. For example, a value of “52” means $5,200 per carat.
It’s important to note: these prices are list prices, not necessarily what diamonds are sold for. Actual transactions may involve discounts or premiums based on demand, cut quality, fluorescence, and certification.
How Jewelers Use the Report
The Rapaport Report serves as a baseline pricing guide for professionals across the diamond pipeline. Here’s how it’s typically used:
- Wholesalers reference it during negotiations with suppliers and retailers.
- Retailers use it to educate customers, especially during custom consultations or high-value purchases.
- Appraisers refer to it when evaluating diamond value for insurance or resale purposes.
While it’s not a direct reflection of all transaction prices, the report ensures jewelers are operating from a trusted, standardized source… essential for maintaining credibility in competitive markets.
Market Influence and Criticism
Over the decades, the Rapaport Report has become a powerful price anchor in the diamond industry. It often sets the tone for weekly price adjustments, especially during volatile market periods.
However, it’s not without criticism:
- It doesn’t reflect discounts, premiums, or lab-grown diamond pricing.
- Prices are derived from trade data, not public transactions, which may not account for all nuances in the market.
Still, most professionals agree that the report remains an essential tool, especially when combined with other real-time pricing data.

- Buy and sell diamonds with verified members
