A diamond's clarity is affected by any detectable external irregularities and internal imperfections created by nature when the diamond was formed. Imperfections such as spots or lines are called inclusions. The less inclusions, the higher the clarity and thus, the greater brilliance and ultimately, value. exact quality of a diamond is critical to its value. A diamond improperly graded by only the slightest margin could dramatically affect its perceived value.
Inclusions can interfere with the passage of light through the stone, diminishing the sparkle and value of the diamond. According to the quality analysis system of the Gemological Institute of America, clarity is graded on a scale ranging from internally flawless (IF) to included (I).
To be graded flawless, a diamond must have no inclusions visible to a trained eye under a 10x magnification in good light.

What is the best clarity grade?
We recommend that you select an "eye-clean" diamond — one that has no inclusions visible to the unaided eye. An excellent value, diamonds of this clarity are much less expensive than IF- or FL-grade diamonds and typically do not contain visible inclusions that detract from the beauty of the diamond. If you're considering an SI grade diamond, call to speak to a diamond and jewelry consultant who will review the diamond to ensure the inclusions are not visible with the unaided eye. But, if you'd rather not compromise on clarity yet are budget conscious, choose a diamond with a good cut and G or H color.
