Grading is a critical process in the jewellery trade, determining the quality and value of diamonds and gemstones through assessments of cut, colour, clarity, and carat weight.

Jewellery Focus provides comprehensive coverage on grading developments, including innovations, certification practices, and insights that help trade professionals navigate this vital aspect of their operations.
