Laser engraving
Diamond laser inscriptions are a growing trend for a technique that provides an easy way to identify a diamond. Without causing any damage, a micro-laser beam is used to etch a microscopic inscription on the girdle of diamonds weighing 0.18 carat or more. Laser inscriptions usually contain the certification laboratory initials and the certifications number.

Laser inscriptions are a nice feature when a diamond owner takes a ring in to get it cleaned, repaired or put in a new mounting because it helps to ensure they get the same diamond back that they brought in. This is especially important for high clarity diamonds that have no inclusion "fingerprints" visible with a 10x loupe.
Keep in mind that this is not the best way to identify a diamond. Inscription can be easily polished out or created on another stone. A laser inscription can be polished off pretty easily if a diamond is stolen or some other scenario. Any store that buys a laser engraving machine can put any inscription they want on any diamond. As a result, if your diamond is stolen do not expect the laser inscription to help you recover your diamond.

Most jewellers can be trusted not to engage in stone-switching but it can happen and does. Keep in mind that this is not always the best way to identify a diamond. There are better ways to identify the diamond e.g. a plot of inclusions. It is good to know what the inclusions in your diamond look like. Show your jeweller or repair person the plot map for your diamond when you take it in and then tell them you would like to compare the diamond under a microscope to match your lab grading report when you get the diamond back from them.
Laser engraving is not approved by all the Diamantaires, some thinks it is an advantage for security and customization, others thinks this is only marketing process denaturing the beauty of natural stones.
