What Are the World Diamonds?
World diamonds are gem-quality and industrial diamonds mined and traded across multiple continents. They are valued for hardness, brilliance, and use in jewelry and technology. Major deposits are found in Africa, Russia, Canada, and Australia.
Major Producing Regions and Supply
Botswana, Russia, Canada, and the Democratic Republic of Congo are among the top producers by volume. Production levels depend on mine capacity, new discoveries, and investment in mining infrastructure. Global supply chains connect mines, cutting centers, and retail markets.
Trade, Pricing, and Market Structure
Diamond prices are influenced by carat weight, color, clarity, cut, and market demand. Rough diamonds are often sold through centralized trading systems and long-term supplier contracts. Industry reports and certification standards help track origin and quality.
