If your jeweler did not disclose the enhancement, you can seek justice from a court of law regarding the same, once you appraise the diamond.

8.      Can you defend your appraisal in front of a Federal Court?

As all appraisals must be accurate and the responsibility of the appraiser, it must be seconded in a court of law.
