Diamonds as commodities are raw, uncut stones extracted from the Earth's crust and traded as valuable resources. They originate from volcanic pipes, approximately 140 kilometers below the surface, where they form under extreme heat and pressure over millions of years.
As a commodity, diamonds are primarily used in the jewelry industry for cutting and polishing into gemstones. However, a small portion is utilized industrially for abrasives, cutting tools, and high-performance coatings. This industrial use accounts for about 20-30% of global diamond production.
Diamonds are mined using various methods including open-pit mining, underground mining, and alluvial mining. After extraction, they are sorted based on carat weight, color, clarity, and cut quality - known as the "four Cs." These characteristics determine a diamond's value in the market.
