No diamond is void of inclusions or imperfections. Even what is graded a IF (internally flawless) has inclusions within it. These imperfections can be observed if one augments the magnification to a degree that more of the imperfections become visible.
Normally diamonds are observed, as far as the IF, VVS1, VVS2 and VS1 clarities are concerned under a microscope using 10x stereoscopic magnification. In reality the magnification is taken at 25x and if an imperfection or inclusion is observed it is then down magnified to 10x and if no longer visible will then be graded as IF in spite of there being an inclusion in the diamond.
Inclusions within a diamond can be of some importance as they can help identify one diamond from another as these inclusions act as a personal 'fingerprint' to the diamond and can be used in their identification in case of loss or if it has been stolen.
This is the good side of the inclusion parameter and as long as the diamond remains 'eye clean' there are other advantages as well, the main one being that the intensity of the inclusion will reduce the value of the diamond and make it, therefore, more accessible to purchase for the less wealthy among us.
Diamonds, however, which contain inclusions or imperfections which will create problems with the light refractive qualities of the diamond are to be avoided as it is better, for the same sum of money, to purchase your diamond engagement ring with a smaller diamond than a bigger one with an aggressive type of imperfection.
Certain inclusions in diamonds can affect the strength of the crystal and in fact, if mounted in a ring may, in time, even crack further and split the diamond in two.
Inclusions within diamonds show themselves in a variety of forms, the most benign being the 'pinpoint' imperfection created by a very small 'bubble' of gas. Sometimes they are found in clusters which will only augment the clarity value the worst being 'clouds' which are hazy and cause severe loss of light refraction. Next are the coloured imperfections created by the inclusion of other materials during the diamond crystal formation period such as carbon (black) or manganese (brown). These come in all sizes and shapes. The next family of inclusions are those of the 'crack' or 'feather' variety they area bit like cracks found in glass and cause 'splinters' called 'gletzes' in the trade jargon. Again these can be white or coloured and can cause severe trouble if big enough or badly placed within the diamond's structure. It is this type of imperfection which can split the diamond at any time so be wary of them and only purchase one from a knowledgeable expert professional who will explain to you in a precise fashion, what you can expect for your money.
There are other types of superficial imperfections as grain lines caused by the imperfect crystal structure of two diamonds within one another in the rough and 'beards' which are left overs of the 'girdling' process which have been badly removed.
These will not hinder the light refractive qualities of your diamond and will not be considered as imperfections and shown within the 'comments' section of a certificate. Severe graining and 'bearding' may be considered as a flaw but these can be repaired in the majority of cases.
Again you will require an expert in order to advise you further so a good source of information can be found by going to www.JewelleryWebShop.co.uk where you will find the help of a REAL diamond cutter and certified gemologist who will be able to advise and educate you further.
