The laser drilling process was invented by Zvi Yehuda in 1965. Some diamonds contain natural black inclusions that are visible to the naked eye. In the laser drilling process a microscopic laser beam is used to drill into the diamond in order to reach the black inclusion. The diamond is boiled in strong acids that clean out the inclusion. After the procedure the black inclusion becomes clear, thus, less noticeable to the naked eye. The process is irreversible and completely stable, The laser drilled diamond should be taken care in the same manner as a non laser drilled diamond. By law, the fact that a diamond has been laser drilled has to be disclosed at every level of sale.
Laser inscription is the process that inscribes the girdle of the diamond (the middle area of the stone) and it is done with a microscopic laser beam. Anything can be inscribed on the girdle, from an identification number to a name or phrase. A trained jeweler, with the aid of the loupe (magnifying glass) will be able to read the inscription. Usually, brand name diamonds will carry their name or logo on the girdle. All of our Yehuda certified diamonds are inscribed with their certificate number and "YEHUDA" as shown below:
