Flawless diamonds in the D colour grade: The absolute best – as good as it gets
Flawless diamonds very rarely occur in nature. Exceptional white+ (D) is the absolute top of the colour scale for diamonds.
An "Ex Ex Ex" grade (excellent cut, excellent polish and excellent symmetry) represents the pinnacle of cutting craftsmanship.
DIAMONDAS offers this top quality for investment diamonds in the sizes of 1 carat, 2 carats, 3 carats and 5 carats.
Our flawless diamonds combine the best features:
- Completely flawless clarity (FL) internally and externally
- The highest possible colour grade for diamonds (D)
- Perfect achievement in all cut criteria
- Only in the desired gemstone sizes
- The world's most renowned certificate from the GIA
Flawless diamonds are rarities and are very seldom available.
Delivery subject to availability.
What is the difference between Flawless (FL) and Internally Flawless (IF)?
All diamonds with these two clarity characteristics are considered "internally flawless", i.e. they do not exhibit any natural impurities under at least 10 times magnification. The Gemological Institute of America (GIA) awards the grade of "flawless" to a diamond if even the smallest traces of processing can no longer be detected on the exterior surface of the stone at this magnification.
How can these smallest traces of processing result with diamonds?
Diamond is the hardest of all natural minerals (with the maximum hardness of 10 on the Mohs scale of mineral hardness). Unlike with emeralds or rubies, there is therefore no other material that can be used to process diamonds. Only diamonds can be used to cut other diamonds – but even then only if they are cut along the grain of the crystal. In the final stage of the cutting process diamond processors strive to achieve a perfect polish. This can only be achieved if an especially fine grain of diamond powder (as if ground to dust) is used on the grinding wheel. But even then it is still possible that the smallest traces of processing can remain on the exterior surface due to two materials of the same hardness grinding against one another. If a gemcutter then attempts to polish away an individual trace of processing in this way then it is possible that this may succeed – but three new ones will be created in doing so] . This means that traces of processing are not due to any lack of craftsmanship on the part of the cutter but rather are a natural and randomly occurring result of the cutting process. Diamonds in the grade "Internally Flawless" therefore include the remark "Minor details of polish are not shown" in the comments on their GIA certificate. Important note: Expect a surcharge of approximately 15% to be added for the purchase of "Flawless" diamonds in comparison to "Internally Flawless" diamonds of otherwise identical quality. Professionals are aware of this technical difference due on random occurrences so it cannot necessarily be assumed that the cost of this surcharge will be able to be recovered in the event of resale.
