DIAMOND TREATMENTS

Diamonds may be subjected to various treatments to improve their appearance. Treatments used are considered usual and customary practices when properly disclosed and when done without intent to defraud the consumer. Treatments found may be laser frilling, clarity enhancement, high temperature and pressure (HTHP) to improve color, or irradiating (to attain fancy color). Some treatments are difficult to detect with standard laboratory equipment. Any treatments found will be noted on the appraisal report. The Federal Trade Commission requires the disclosure of all current diamond treatments. Failure to do so may be considered deceptive to the consumer.
