Clarity
Clarity grades range from "l"(Imperfect)to "FL"(Flawless).
It is possible to find some imperfections in almost every diamond:tiny feathers and clouds-inclusions- that affect a diamond's value.
A diamond is said to be "flawless" if no inclusions or superficial blemishes can be seen under a standard 10-power jeweler's loupe.
Truly flawless diamonds are extremely rare.
