Diamonds are a valuable trade commodity known for their brilliance and hardness, with a primary origin in Kimberlite pipes and alluvial deposits found mainly in countries such as Botswana, Russia, and the Democratic Republic of Congo.
Their value is determined by the "four Cs": cut, color, clarity, and carat weight. Diamonds are used in various ways: they serve as the centerpiece of luxury jewelry items like engagement rings and necklaces, while their extreme hardness makes them ideal for industrial applications such as cutting tools and drill bits. Diamonds have also been employed as a store of value, often vaulted as an investment similar to gold.
The global diamond trade is complex and regulated, with key players including mining companies, cutters, manufacturers, and retailers. The Kimberley Process Certification Scheme helps prevent conflict diamonds from entering the supply chain. Rough diamonds are traded in various forms, such as parcels, lots, or single stones, and their production requires input materials like industrial-grade diamonds, diamond saws, lasers, polishing wheels, and diamond dust.
