Flawless & Internally Flawless Clarity Diamonds

In the realm of diamonds, Flawless (FL) and Internally Flawless (IF) gems epitomize purity and rarity. These diamonds, distinguished by their clarity grades, either lack any inclusions and blemishes or possess only minor surface imperfections. A Flawless diamond is a rare marvel, with D color (perfectly colorless) IF diamonds representing a mere 0.001% of global diamond production. Despite their close resemblance, FL diamonds can command prices up to 30% higher than IF ones. For those seeking the pinnacle of diamond perfection, these gems offer an unmatched allure, symbolizing both nature's impeccable craftsmanship and ultimate luxury.

Flawless Diamonds: The Epitome of Purity

Flawless diamonds are the zenith of diamond clarity, representing a level of purity that is exceptionally rare in nature. These diamonds are completely devoid of any inclusions or blemishes, even under 10x magnification. Their pristine nature is further accentuated when they belong to the IIa category, which comprises only 1-2% of all diamonds. These IIa diamonds are chemically pure, making them devoid of any nitrogen impurities, and thus, they exhibit a unique transparency.

A CUT ABOVE® Collection Series Diamonds takes this rarity a notch higher by offering diamonds that are not only Flawless but also belong to the DEF color range, signifying they are colorless. These diamonds, combined with FL-VVS purity, are the crème de la crème, often referred to as "collection" or "investment" quality. They are the embodiment of perfection, offering unparalleled brilliance and fire.

Internally Flawless Diamonds: A Close Second

Internally Flawless (IF) diamonds, while just a step below Flawless, are still a marvel in their own right. These diamonds have no internal inclusions, with only minor blemishes visible under 10x magnification. Such blemishes could be a tiny scratch or abrasion, often not visible to the naked eye. The distinction between Flawless and Internally Flawless can be so subtle that even diamond experts might find it challenging to differentiate between the two.

However, the allure of an IF diamond is undeniable. They offer a purity that ensures minimal interference with light, allowing a precision-cut diamond to maximize its light performance. While they might not command the same premium as Flawless diamonds, IF diamonds, especially those from renowned collections like A CUT ABOVE®, represent a harmonious blend of rarity, beauty, and value. You may also find options with the Astor Diamonds from Blue Nile and True Hearts from James Allen.

Are Flawless and IF Diamonds Worth It?

The allure of Flawless (FL) and Internally Flawless (IF) diamonds is undeniable. Representing the pinnacle of clarity, these diamonds are the embodiment of nature's perfection. But the question arises: Are they worth the premium they command?

The answer largely depends on individual preferences and values. For those who prioritize the utmost purity and perfection in a diamond, FL and IF diamonds are undoubtedly worth the investment. They offer unparalleled clarity, ensuring that the diamond's brilliance and fire are maximized without any interference from inclusions or blemishes. Moreover, owning such a diamond is a testament to possessing one of nature's rarest creations, adding a unique sentimental value.

However, it's essential to understand that while these diamonds are the epitome of clarity, other diamonds with slightly lower clarity grades can also be stunningly beautiful and offer better value for money. The decision ultimately boils down to personal preferences, budget, and the significance attached to the diamond's purity.
