The diamond has been tested with our certified diamond tester here in store and it is an authentic natural diamond, not lab. There is no personalization on it, and it is approximately 1-1/4" from top to bottom, including the bail. It it marked 14KT on the bail, which I have shown. It has small red gems in the eyes, an enamel clock which is set at the 11th hour, a yellow gold moose and a white white gold background.
