In the Four Cs section we've already touched upon the notion of “flawless diamonds”, but it feels that it wasn't stressed enough for you. For flawless diamonds are indeed a true miracle of nature. They are very rare and mesmerisingly beautiful. The following is to give you an idea of how precious flawless diamonds are. It's not an uncommon occurrence to find a perfectly white diamond, which has a few imperfections. But to discover a diamond with an ideal colour and no imperfections whatsoever is an opportunity that comes but almost once in a lifetime. One can only imagine the stir among the industry professionals caused by the Millennium Star, a 273.15 carat world's second largest flawless diamond when it first went on display for general public back in 1999.
Basically, flawless diamonds are stones at the highest end of the scale in terms of colour and clarity. So it is only when a diamond can boast an extremely rare combination of the perfect colour as well as the perfect clarity that it is considered flawless. In other words, flawless diamonds are the whitest and clearest stones possible. These are graded with a D in colour, denoting the purest white colour available in diamonds, as well as with an IF (internally flawless), meaning that the stones are completely clear of any blemishes or inclusions. It goes without saying that flawless diamonds always fetch a higher price.
However, even though flawless diamonds are pretty rare, it doesn't mean you cannot acquire a diamond that would look flawless to the naked eye. Today, rough diamonds undergo highly advanced cutting procedures, that allow the cutter to take a D-colour diamond and masterly hide all the imperfections of the stone. So technologically-enhanced D-colour imperfect diamonds can appear flawless to the naked eye, but they still will be priced lower than naturally occurring flawless stones.
