The inner content of diamonds refers to all the characteristics that affect the diamond clarity. Different types of internal contents have different degrees of influence on clarity. It includes two types of internal content and external defects. Inner content refers to defects inside the diamond that can reach the surface of the diamond. Observing internal content is very important because they are the main factor that determines the level of diamond clarity.nThe type of inside is as follows:n【Crystal】nCrystals refer to all mineral crystals with obvious three -dimensional geometry in the diamond, and the crystals can be divided into colorless or light -colored parcels and dark or black parcels.n【Points】nThe smallest visible package inside the diamond. It looks like a small white dot under 10 times the large mirror.n【Cloud -like】nThe hazy or emulsion without a clear boundary in the diamond may be composed of many small dots or a kind of empty. Clouds often depend on the symmetrical axis distribution of diamonds (related to the history of diamonds), and sometimes some black -sized dots can also appear in white clouds.n【Feather -like patterns】nThe cracks in diamonds due to lax or tension look like feathers. If the feather -shaped pattern is relatively large, it can be called "crack", and sometimes semi -round feather -like patterns can be seen.n【Beard waist (hair edge, beard)】nThe beard -shaped cracks that exist in the waist are deep inside, shaped like the beard of the elderly, which is caused by excessive rough grinding.n【Internal texture】nThe growth traces caused by the irregular arrangement of the diamond in the diamond are often straight linear. If it is white, color or reflective, it will affect the clarity.n【Dual Crystal Center】nThe central point of the crystallization structure is often accompanied by a little object. 【Caval Crystal Plane】nThe original crystal surface inside the diamond is concave.n【Laser Pole】nThe holes left by laser beams and chemicals removing the dark parcel inside the diamond, shaped like white funnel or pipes, can be filled by high refractive index glass.n【Truis (Stimulation)】nThe surface of the diamond was hit by external force and extended into the diamond.
