The results will be documented in a Jewellery Report that will disclose any treatments that have been discovered. If a value is requested then an appraiser will give an estimated replacement value and issue a full Appraisal Report. If any stone has been set in such a way that makes it impossible to accurately test then with the owner’s permission the gem may be unset for testing as loose.
