Article Topic: Discussing the pro’s and con’s of laser inscribing and an overview of the process of laser inscribing diamonds.

Gem Material: Diamond
Author: Ronnie Bauer
Abstract from Article:
‘The process of inscribing a logo, message or a series of numbers on the girdle of a diamond is only limited by the diameter and quality of the girdle. In reality, only two things are usually inscribed: the logo of the grading lab and the certificate number. However we have had instances where the branding of a diamond is important to the retailer so in addition  the store’s logo or less often love messages.’
