diamond trading

Diamond trading involves the buying and selling of rough and polished diamonds between miners, traders, wholesalers, and retailers. It operates through a global network governed by industry standards and certifications to ensure quality, authenticity, and ethical sourcing. Traders assess diamonds based on Carat (weight), Clarity (internal flaws), Color, and Cut—known as the 4Cs—to determine value. Prices fluctuate with market demand, supply, and economic factors. The process includes negotiation, grading, and sometimes certification by authoritative labs. Overall, diamond trading balances technical assessment with market strategies to facilitate the flow of diamonds from extraction to end consumers.
