A Lesson in Diamond Clarity

What Is Diamond Clarity?

Diamond clarity describes the absence or presence of flaws inside or on the surface of a diamond. A stone with perfect clarity is rare, and most flaws that do exist can’t be seen without seeing them through a jeweler’s magnifying loupe.

Terms You Should Know:

Diamond Inclusions: These are imperfections, or flaws, inside of a diamond. This includes tiny spots of white, black, or other colors or cracks. Flaws like these may cause no problems at all, but some could cause the stone to split.

Diamond Blemishes: Blemishes are flaws on a diamond’s exterior surface. These exterior flaws are the result of the diamond cutting and polishing process.

The Gemological Institute of America (GIA) grades diamond clarity using 10X magnification. They classify diamonds as:

  • Fl, Flawless: No internal or external flaws.
  • IF, Internally Flawless: No internal flaws but has slight external blemishes.
  • VVS1 & VVS2, Very, very slightly included: Minute inclusions that are difficult for even an experienced grader to detect.
  • VS1 & VS2, Very slightly included: Minute inclusions that aren’t easily seen by an experienced grader.
  • SI1 & SI2, Slightly included: Inclusions that are noticeable to an experienced grader.
  • I1 & I2 & I3, Included: Obvious inclusions that can affect transparency and brilliance.
