De Beers Selects Oxford University Developed Laser Marking for LGD JewelryJune 03, 18
(IDEX Online) – De Beers will be using Opsydia, an Oxford University venture, to create tiny laser markings on its new lab-grown diamond range, Lightbox Jewellery.
Opsydia creates the markings below the surface of diamonds using high precision lasers, making it economically unviable to attempt to remove them.
They are less than 1/50th of the width of a human hair and so small that they have no effect on the grading or quality of the gems.
Steve Coe of Lightbox said: “This internal laser marking technology will provide a robust means for the simple, visual identification of the stones in Lightbox Jewellery as being laboratory grown, while at the same time providing assurance to consumers that this product has been manufactured to high standards by a world leader in this field.”
