What are commercial diamonds worth?

How much commercial diamonds are worth varies greatly. Commercial diamond refers to natural and lab-created diamond gemstones of I, J or K color quality. Because they are not completely colorless, they are generally worth less than stones with higher color grades. However, the carat weight, cut and clarity will also impact the potential value. The best way to find out how much a particular diamond might sell for is generally to have a certified appraiser or experienced jeweler assess it.
