DIAMOND CLARITY

It is possible to find some imperfections
in almost every diamond: tiny feathers and
clouds - inclusions - that affect a diamond's
value. Clarity grades range from
"I" (imperfect) to "FL" (flawless).
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.
