FL (Flawless) vs. IF (Internally Flawless) Clarity Diamonds - Understanding the Differences and Making the Right Choice
When selecting a diamond, clarity is one of the most significant factors that influence its overall appearance and value. Two of the highest clarity grades available are FL (Flawless) and IF (Internally Flawless) diamonds. While both are exceptional, there are subtle differences between them that could impact your decision depending on what you value most in a diamond.
In short: Flawless (FL) means no inclusions or blemishes visible under 10× magnification; Internally Flawless (IF) means no inclusions, but may have minor surface blemishes from polishing. To the naked eye and even under 10× magnification, both look identical. IF costs roughly 10-20% less than FL with no visible difference — better value at the top of the clarity scale.
What Are FL (Flawless) Diamonds?
FL diamonds are the epitome of perfection in the world of diamonds. These stones are entirely devoid of any internal inclusions or external blemishes when viewed under 10x magnification by a trained gemologist. This level of clarity is incredibly rare, with only a minute percentage of all diamonds achieving this standard. The absence of any imperfections ensures that the diamond reflects light at its maximum potential, resulting in an extraordinary brilliance and fire.
However, the rarity of FL diamonds also means they come with a higher price tag. For those seeking a flawless gem, this grade is the ultimate choice, symbolising purity and absolute perfection.
