Cold Laser Inscription, confidence

The Spark of Confidence

Cold Laser Inscription

Laser inscription is the use of a very fine, precise laser beam to write a grading report number or customised personal message on the girdle (outside perimeter) of a diamond. The laser inscription is totally invisible to the naked eye and can only be seen with a magnifying loupe. It does not change the colour or clarity grade of a diamond and is considered permanent as it can only be removed by a professional diamond cutter. The DCLA uses the latest cold laser technology that allows excellent control during inscription without damaging the diamond (unlike a hot laser). Laser inscription will ensure that the diamond set in the ring is the same as the one described in the grading report. At a later stage if you decide to remake or polish your ring the inscription will ensure that your diamond has not been swapped.

Important Notice

The DCLA uses the most advanced PhotoScribe cold laser inscription technology. PhotoScribe is the only company in the world that guarantees in writing that their patented ´cold´ lasers will not crack or fracture your diamonds. If the stone has been laser inscribed, the inscription details will appear on the certificate. Check your certificate to see if your diamond is laser inscribed. Browse this certification guide to see where this would appear on your certificate.

The DCLA Laser Inscription Guarantee

There has recently been misrepresentation of the difference between hot and cold laser technologies used for diamond inscription. We would like to clarify the facts of the technologies, illustrated in the images below.

  • "Hot" lasers can fracture diamonds. "Cold" lasers do not.
  • "Hot" lasers can penetrate diamonds causing inclusions and blowing existing inclusions close to the surface. "Cold" lasers do not.

Hot and Cold lasers are technologically two very different types of lasers. Technically, there are many reasons the cold laser technology is far superior to hot lasers for diamond inscription. However, all reasons lead to the single most important point for you and your customers to understand. Unlike hot lasers, cold lasers are 100% safe for diamonds and will not chip or fracture your stones.

GIA, AGS, EGL, HRD, GCAL, and all other major labs around the world all use PhotoScribe lasers. DCLA in Australia also uses the PhotoScribe cold laser technology.

DCLA is so confident in the cold laser technology that we use, that we will guarantee, in writing, that our laser inscription will not chip or fracture your diamond.

Ask others to offer the same written guarantee that we offer and you will see that only the cold laser technology is 100% safe for the inscription of polished diamonds. It is no coincidence that the cold laser system that is used by DCLA is manufactured by the same company that manufactures the cold lasers that are used by all the major labs around the world. DCLA invest in the best and latest technology in order to serve our customers better.
