Operations of top diamond exchanges

Operations of top diamond exchanges

The article discusses the Antwerp Diamond Center as one of the largest and oldest diamond exchanges in the world, established in 1904, which plays a leading role in international diamond trade. It explains how diamonds are priced based on the "4 Cs" standards (cut, color, clarity, and carat weight), and the Rapaport price list, which is considered the primary reference in determining their value. The article also highlights regulations of global exchanges, such as the World Diamond Council, to ensure transparency and integrity in operations, and emphasizes the necessity of issuing Kimberley Process certificates for each shipment to prevent the trade of "blood diamonds." Additionally, it covers the main countries involved in diamond production and importation, detailing the volume of trade and exchange methods, underscoring Antwerp's significance as a key hub in this global industry.
