Clarity refers to the purity or cleanliness of a diamond. This is determined by the number of inclusions a diamond might have and is determined by a gemologist, who inspects the diamond with a 10x magnification glass.
The Diamond Clarity Chart
Measured on a scale from Flawless (FL) or Internally Flawless (IF) to Included – I1, I2 and I3 – this diamond clarity chart helps you choose the best diamond. Just remember, the more internally flawless a diamond is, the sparkler is going to be.
How to choose the perfect clarity grade?
Everything will depend on the diamond shape and carat you are going for. For example, if you choose a Brilliant cut like Round, Princess or Oval, you can get away with choosing a lower grade because this shape helps hide inclusions better than step-cut diamonds like Emerald or Ascher. If you are going for a step-cut, always select a higher clarity grade.
