As you may know, diamonds are graded according to the 4C’s inherent in every stone: color, cut, clarity, and carat. The diamond clarity grades range from F (Flawless) to I3 (Included). IF (Internally Flawless) is a clarity grade that comes right next to F. This grade can be considered roughly flawless, with the stone having superior quality and perfection than the grades below.
Getting an F or IF diamond is hard, because of the rarity of flawless diamonds in nature. This, in turn, contributes to the high price of such stones. Being flawless, these diamonds do not have many flaws even when examined under 10x magnification. If you are planning to buy an IF clarity diamond ring, be ready to spend thousands of dollars on the purchase.
The F and IF grades have something that differentiates them. The key difference is that IF diamonds have minor blemishes on the surface, known as polish marks, and this makes these diamonds internally flawless rather than completely flawless. If you plan to buy a top quality diamond ring, consider buying an IF clarity diamond ring, as it would come at a lower price than a flawless one, while still looking as gorgeous as the latter.
