gemstone valuation

Gemstone valuation involves assessing key qualities that determine a stone’s worth: color, clarity, cut, and carat weight, known as the "Four Cs." Color measures hue and saturation; clarity gauges internal flaws; cut affects brilliance and symmetry; and carat weight considers size. Additionally, origin, rarity, and market demand influence value. Experts may also consider treatments or enhancements. Overall, valuation combines these factors to establish the gemstone’s quality and market price, ensuring a fair assessment for buyers and sellers alike.
