Clarity of Diamonds

Since I've interest in diamond I think I should learn about the Clarity of Diamonds.

Clarity is an important aspect of a diamond, and it is important to know how to grade the clarity of a diamond before you buy one. I was told that it is actually quite easy to learn how to grade the clarity of a diamond. I've learned that there are basically two things that you must understand about the clarity of diamonds: Diamonds with visual inclusions and blemishes, and those that are ‘eye clean’ meaning that there are no inclusions or blemishes that can be seen with the naked eye. From there, the clarity of a diamond is further broken down into subcategories.

Many people mistakenly think that diamond clarity refers to how clear it
is. This isn’t so. Clarity actually refers to the internal and external
imperfections of the diamond. The best diamonds, of course get a grade of
FL or IF – Flawless or Internally Flawless – meaning that it is perfect. A
grade of I-1, I-2 or I-3 means that the diamond is imperfect, with a grade
of I-3 being the worst.

Other grades are VVS1 and VVS2, which means that the diamond is very, very slightly imperfect; VS1 and VS2, meaning the diamond is very slightly imperfect; SI-1 and SI-2, which means that the diamond is slightly imperfect.
