Appraising Your Opals
Loretta Clayton·October 03, 2025

When having an opal appraised, be sure to work with a qualified gemologist—like the staff at Heritage Appraisers—who understands the unique grading factors that influence value. Unlike other gemstones, opals are not judged solely by the traditional “4 Cs.” Instead, qualities such as play-of-color, brightness, and body tone play a major role.
To get the most accurate appraisal, bring any supporting documents you may have, such as purchase receipts, old appraisals, or records of origin. These details can help confirm important information about your stone.
