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.


Carats measure a stone’s weight. The higher the carat weight, the heavier and bigger a center stone. Use the slider to see how diamond size changes with carat weight.
The size of a diamond is proportional to its carat weight. When rough diamonds are cut and polished into finished diamonds, up to 2/3 of the total carat weight may be lost. Since larger rough gems of high quality are found less frequently than smaller rough gems of high quality.
A diamond’s cut measures its anatomy and ability to reflect light. Cut grades go from “Excellent” to “Poor”. Well-cut diamonds have outstanding proportions with immense fire, brilliance, and scintillation.
