A jewelry appraisal and a gemstone grading report serve different purposes. They may be used together, but one should not be treated as a substitute for the other.

What a jewelry appraisal does

An appraisal describes a finished piece and states a monetary value for a specific purpose, such as insurance replacement, estate planning, or fair market analysis. It may include the setting, metal, workmanship, condition, gemstones, photographs, and assumptions used to estimate value.

What a grading report does

A grading report generally documents the characteristics of a particular loose or mounted gemstone using the laboratory’s procedures and terminology. Depending on the stone and laboratory, it may report measurements, weight, color, clarity, cut information, treatments, identification, and an identifying report number.

The key distinction

A grading report usually does not assign a retail replacement value to the finished jewelry. An appraisal may rely on a grading report, but it also considers the mounting, labor, design, condition, and market context.

Why the numbers may not match sales language

Carat weight, dimensions, color, clarity, and treatment descriptions can be estimates when a stone is mounted. Different laboratories and appraisers may use different methods, tolerances, and terminology. The scope of each document should be read carefully.

Which document may be useful?

• Use a grading report to document gemstone characteristics.
• Use an appraisal when a stated monetary value and finished-piece description are needed.
• Keep the receipt to document the actual transaction price.

Together, these records can provide a more complete picture of what was purchased, how the gemstone was described, and what value was assigned for a particular purpose.
