Often mistaken as a unit of size, a carat actually measures the weight of a gemstone, with 1 carat equaling 0.2 grams.

Clarity
SI2: Easily detected, but invisible to the naked eye
Clarity refers to the transparency of a diamond. It is assessed by observing the diamond under a 10x magnification loupe, evaluating the size, number, position, quality, color, and visibility of inclusions, as well as any scratches or wear that occur after cutting. The grades range from 'FL (Flawless),' where no imperfections or defects are observed, to levels where inclusions are visible to the naked eye, categorized into 11 grades.
