Overview of How Jewelry Buyers Evaluate Gold, Silver, and Diamonds

Different materials require different evaluation techniques.

• Gold is assessed for purity, weight, and market price.

• Silver is evaluated for fineness, craftsmanship, and tarnish resistance.

• Diamonds are graded using the globally recognized 4Cs—cut, color, clarity, and carat weight.

Jewelry evaluation helps maintain transparency and supports consumers, traders, and manufacturers by setting objective standards for pricing.
