Ultimate perfection in the world of certified diamonds is the D FL or "D Flawless." This is a diamond that is completely colorless with no internal inclusions ("flaws") and no blemishes on any of the facets when viewed under 10x magnification. D Flawless diamonds are exceedingly rare.

The term "D Flawless" is also used in reference to diamonds with a grade of D IF. These are colorless diamonds that are Internally Flawless , but may have a minor blemish on the exterior of the stone.

A diamond of perfect color and clarity (D FL or D IF) is referred to in the trade as a "gem diamond." So when diamond dealers refer to "gems" they are talking very specifically about D Flawless diamonds.

Diamond color grades refer to the "body color" of the stone. Well-cut D color diamonds will still exhibit "fire" which is the prismatic effect of light being broken into its component colors as it travels through the stone and is refracted back to the eye.

Because they are so rare D Flawless diamonds are substantially more costly than top quality diamonds just a grade or two lower and which look the same to the naked eye. It is estimated that of all the diamonds mined only 0.001% will produce D Flawless finished stones. In the world of certified diamonds you will pay a stiff premium for ultimate perfection.

The largest D Flawless diamond in the world was unveiled in 1999. The astounding 203.04ct pear shape gem is known as The DeBeers Millenium Star.
