The clarity of a diamond is classified according to the number of inclusions. Clarity ranges from internally flawless (FL-IF), which describes a diamond that has no external or internal inclusions, to included (I1, I2, I3) diamonds, where one can easily see inclusions with the naked eye.
All Hartmann’s diamonds are at the higher end of the clarity spectrum. Carefully chosen so that any stone with obvious inclusions is instantly discarded. We never buy diamonds with inclusions that detract from the stone’s beauty.
