* G-H-I-J (nearly colourless)
* K-L-M-N (faint)
* O-P-Q-R (very light)

• Clarity – unknown to most people, diamonds have flaws and are not entirely perfect. These internal features are known as inclusions, while its surface irregularities are known as blemishes. These flaws are called clarity characteristics. Therefore the clarity of a diamond refers to the absence inclusions and blemishes.
