Clarity is measured by the number and size of the inclusions (also known as imperfections).

Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. The process can result in a variety of internal characteristics called "inclusions" and external characeristics called "blemishes". 

When a diamond grader evaluates clarity it involves determining the number, size, relief, nature, and position of these characteristics. Also, how these affect the overall appearence of the stone. While no diamond is perfectly pure, the closer it comes, the higher the value.

Many inclusions and blemishes are too tiny to be seen by anyone other than a trained diamond grader. To the naked eye, a VS1 and an SI2 diamond may look exactly the same, but these diamonds are quite different in terms of overall quality. This is why expert and accurate assessment of clarity is extremely important.

What Clarity Grade Is Right For Me?

  • Select an "eye-clean" diamond - one that has no imperfections visible to the unaided-eye through the crown. An excellent value, diamonds of this clarity are much less expensive than flawless (FL) or internally flawless (IF) diamonds, which are extremely rare and command higher prices.
  • Frequently, imperfections in diamonds graded slightly included (SI) are not visible to the unaided eye, making them an excellent value. If you're considering a diamond with an SI clarity grade, call to speak to a diamond and jewellery consultant who will review the diamond to ensure the imperfections are not visible to the unaided eye.
