Diamonds that are absolutely clear are very rare, the most sought-after and therefore the most expensive. But most diamonds have inclusions ΓÇö scratches, trace minerals or other tiny characteristics that can detract from the pure beauty of the diamond. The GIA, AGS and IGI labs use a detailed system of rules and standards to summarize, note and mark the number, location, size, and type of inclusions present in a diamond.

Diamond Clarity

FL, IF Flawless, Internally Flawless: No internal or external flaws. Internally Flawless: No internal flaws. Very rare and beautiful diamonds.
VVS1, VVS2 Very, Very Slightly Included: Very difficult to see inclusions under 10x magnification. An excellent quality diamond
VS1, VS2 Very Slightly Included: Inclusions are not typically visible to the unaided eye. Less expensive than the VVS1 or VVS2 grades.
SI1, SI2, SI3 Slightly Included: Inclusions are visible under 10x magnification, and may be visible with the unaided eye. A good diamond value. if you select a diamond from this category please contact us to ensure the diamond is eye clean.
I1, I2, I3 Included: MDC does not carry diamonds of I-grade clarity.

Note that MDC also offers Natural fancy-colored diamonds. These diamonds are graded on a different color scale than white diamonds. Since the scale above ranges from the best to the worst quality in a white diamond, the yellow color in fancy-yellow diamonds cannot be found on this scale.

Which Clarity Grade Is Best?

We recommend that you select an “eye-clean” diamond ΓÇö 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 H or lower color.

Which Color Grade Is Best?

  • For the purist, look for a colorless diamond with a grade of D-F and a fluorescence rating of faint, inert, none, or negligible.
  • For an excellent value in a diamond with no noticeable color to the unaided eye, look for a near-colorless grade of G-I, and a fluorescence grade of medium or strong blue.
  • Or, if you’d rather not compromise on color but would like to stay on budget, choose a diamond with a good cut, SI1ΓÇôSI2 clarity, and consider going with a strong fluorescence. It will still be beautiful to the unaided eye and you may prefer the unique effect of a strong fluorescence.
