The GL 5200 Clarity machine is used by grading labs, manufacturers, and internet retailers for grading clarity and for measuring and precisely mapping inclusions in polished and rough diamonds.

In a manufacturing facility the system is used for inclusion measuring and mapping in clear, frosted and coated rough to help with the cutting operation and for evaluating a finished good on clarity grade.

A special cleaning instrument first cleans the diamond, which is then immersed in a non-toxic liquid for imaging. Depending on the clarity of the diamond, a single image may be required or multiple images may be needed. Clear stones (IF through VS2) require more time to be imaged, as multiple passes are required.

Once the gem is scanned, the template is presented on the screen with the inclusions mapped, and then the gemologist reviews the plot.
