Clarity Grading

The majority of Diamond Inclusions cannot be seen by the human eye so systems have been developed to grade diamond clarity. The different types of diamond grades reflecting clarity are detailed on the Diamond Clarity Chart. Diamond grading on a Diamond Clarity Chart ranges from high quality, rare and expensive flawless to imperfect and cheap diamonds.

As the majority of inclusions cannot be seen by the naked eye, they are located by a jeweller under a 10 power magnification and then graded according to their clarity. The grading and levels are described on the Clarity Chart. An excellent grading guide when choosing diamonds.
