The diamond clarity grading ranges from flawless (FL) to included (I3) according to the GIA clarity grading system. The diamonds clarity grade may vary depending on the number, size, position, color and nature of the imperfection.

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.

All Le Lumiere’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.
