You can see the flaws with the help of a 10X microscope. Only a 10X microscope can help you if you want to know the clarity scale of your diamond.
If you want to know the most common and modern grading scales, then they are available here. These grading scales are from the GIA which is abbreviated as Gemological Institute of America. The following are the most popular types of grades in the international market through which you can judge the clarity of the diamond.
- FL: You can give FL scale to those diamond that doesn’t have any inclusion or the blemishes. It means the diamond will be flawless.
- IF: This scale will tell you the presence of flaws in the diamond. If you will give this scale to your diamond, then it will be internally flawless.

- VS: You can give VS scale to those diamonds that have slight flaws. It will have VS1 and VS2 subgrades.

Different types of diamond color scales:
The color of the diamond will tell you about the yellow hues. Other than this, the color will also tell you about the visibility of flaws and blemishes. The GIA has 5 coloring grades. All jewelers use these 5 color scales to determine the coloring scheme of a diamond to detect the clarity.

- Faint yellow: If there will be a very faint yellow color inside the diamond, then you need to give it a faint yellow color scale. On the other hand, you can also declare K, L or M scale stone.
- Very light yellow: Stones in the N, O, P, Q and R will have yellow tints inside or on the outer surface. In these cases, you can’t give a colorless scale to the diamond.
- Light yellow: In this case, the diamond will show a clear yellow color. The scale that you can give to your diamond is, S to Z.

we bought a d fl diamond a few years ago and had it mounted in a simple setting where it is kept in the bank. Recently we were told that it is possible the setting of the diamond may have made it an IF and no longer a FL diamond. Also online we saw an article saying an IF diamond can be worn to the point that it is now a VVS1. Is any of this true? In addition, we are thinking of having the diamond reset, insured and worn. Is this wise or is it setting up the diamond for a decrease in its quality? Thank you very much for any information. sincerely,
I suggest you to keep your D FL diamond, which is rare and very expensive now and highest in the quality.
