A diamond responds to incident light in three different ways. It allows a portion of light to pass through itself; it reflects another portion and refracts yet another portion of the incident light within itself. This dispersion and refraction of light is what makes the diamond sparkle.When the path or wavelength of incident light is obstructed or diverted, the play of light does not occur. Depending on the size and type of the obstruction, this can impart a dull and lifeless look to the diamond.
Such obstructions are caused by flaws of the diamond that may either be internal or external or both. External flaws occurring on the surface of the diamonds are 求婚戒指一卡 called blemishes while internal faults occurring within the crystalline surface of the diamond are known as inclusions.Inclusions are acquired naturally by diamonds during their formative years deep within the womb of mother earth and are akin to birthmarks. These flaws are created due to irregular crystallization of diamond during its formation process.
Blemishes can be man-inflicted during mining, cutting & polishing or they may also have been acquired naturally.One must understand clearly that diamonds are formed deep within the earth in the crudest of environments under unimaginable conditions of temperatures and pressures. These conditions are far removed from those of a sterile laboratory.As a result, it is normal for diamonds to have inclusions. Inclusions are present in diamonds as a rule rather than as exceptions.
Nevertheless, inclusions need not be looked upon with distaste, if they are small and have a negligible effect on the brilliance and clarity of a diamond. In fact, the inclusions present in individual diamonds are as unique as the human fingerprint and are recorded in detail in the diamond’s gradation report.Most inclusions do not affect the beauty of a diamond and are considered to be identifying characteristics. They allow you to properly identify your own diamond in case it happens to get lost or stolen or mixed up with other diamonds when given for cleaning or appraisal.
