Diamond FL has the best clarity. Diamond clarity is one of the 4C standards for diamonds, used to measure the quality of diamonds. The clarity of a diamond, like its color, is also graded. The higher the clarity grade of a diamond, the more transparent and flawless it is, and the more brilliant it is. As a result, the price naturally increases.
What are the clarity levels of diamonds
Flawless Level (FL): When viewed under a 10x magnifying glass, diamonds have no inclusions or surface flaws
Under a 10x magnifying glass, there are no inclusions inside the diamond, and there are insignificant flaws on the surface that can be removed by polishing.
Under a 10x magnifying glass, there are extremely fine flaws inside the diamond, which are difficult for even professional appraisers to see.
Slight inclusions (VS) can be observed under a 10x magnifying glass, and diamond flaws are visible but very small.
Under a 10x magnifying glass, diamonds with micro inclusions (SI) exhibit clear and visible flaws.
The internal level (I) flaws are very obvious under a 10x magnifying glass and can also be seen with the naked eye, which affects the diamond's strength, transparency, and shine.
