Important note on physical gemstone verification:
Verifying a report number in an online database confirms that an official report exists with those reported characteristics. However, online lookup validity alone does not physically authenticate that an unmounted stone matches that certificate without verifying the girdle laser inscription and physical millimeter dimensions under magnification.
