Diamond clarity – determining the diamond's clarity

In order to evaluate the clarity of the ​diamonds correctly, a microscope or loupe is used to enlarge the stone 10X. This method is used internationally. The clarity scale is divided into several different categories, ranging from ‘flawless’ to ‘included’ (visible defects).

Diamond clarity grading – the GIA scale

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.
