Marking on Diamond Table Surface
Conventional diamond marking is usually done with a micro-laser beam to etch a microscopic inscription on the diamond girdle, yet it carries no differentiation with other technology and is extremely low cost to reproduce. This implies people without much technical expertise could do so thus provides low values in anti-counterfeit purpose. MD has successfully developed series of avant-garde anti-counterfeit marking technologies which are to etch mark on diamond table surface. The marks created are with nano-size, have high opacity, and do not constitute a visual flaw, nor do they affect the diamond color and clarity grading result.
