It is important to understand there are two very different categories of lasers used for diamond inscription; hot lasers and cold lasers. Hot lasers are YAG lasers and Cold lasers use Excimer laser technology.

Simply put the PhotoScribe Cold laser system is the only laser system guaranteed 100% safe for diamond inscriptions.

Hot lasers will chip or fracture diamonds. High quality polished girdles are especially at risk for fracturing or chipping with "Hot" lasers.

The picture is a classic case of the damage done by hot laser. This will lower the value of your diamond by changing the clarity grade or polish grade of the diamond.

Make sure your diamond is Cold Laser inscribed before you buy it.
