Understand your diamond Qualities
Color refers to the natural tint of a diamond. The closer the diamond is to “colorless” the rarer it is. The industry standard to grading color in a diamond is to assign a letter grade from D (colorless) to J (nearly colorless)
Most diamonds have imperfections in the form of internal flaws and surface blemishes. These imperfections are graded on a scale of FL (flawless) to I1-I3 (included). FL diamonds are the rarest and hardest to find.
