Clarity
Clarity refers to the internal and external birthmarks of the gemstone. Similar to fingerprints or snowflakes, it’s these naturally occurring inclusions that make each gem in the world unique. As indicated in the chart below, the quantity inclusions in a gemstone increase as you move from left to right. The grading is based on 10 power magnification. The usual benchmark in deciding on clarity is whether you can see the inclusion with the naked eye.
