Clarity indicates the clarity of the diamond, which is evaluated by observing it with a 10x magnification loupe
and comprehensively evaluating the size, number, location, quality, color and prominence of inclusions,
as well as any abrasions or scratches that occurred after the cutting process.
Grades are divided into 11 grades, from "FL (flawless)" with no scratches or defects at all,
to those with inclusions visible to the naked eye.
