Diamond symmetry and diamond prices

The symmetry of diamond in diamond cutters rating, symmetry and polishing is the grading diamonds eventually cut two factors when necessary. Symmetry is crucial for diamond appearance, it is a diamond on all aspects of the exact arrangement and perfect symmetry parallelism. It can be subdivided into two types of features: the section characteristics and proportion of related features. Based on GIA rating system, symmetry has 5 levels. Diamond appraiser, normally use 10 times the magnifying glass, microscope or dark field illumination function, to help to observe and define diamond cutters. Five grades were excellent, good, good, fair, poor. When the diamond no problem of all kinds of symmetry, or when using 10 x magnification microscope observation of diamond, the degree of asymmetry extremely small, almost invisible positive observation, so the diamond can be rated as excellent. The opposite is bad grades, obviously, the grade of diamond looks not harmonious, even with the naked eye could see that. For example, each section of imbalances, contour is not round, desktop or pavilion pointed to. Can be found in the finished product after polishing diamonds on the facet of the relevant characteristics if symmetry problem related to the tangent plane, it means that the following characteristics may be present, diamonds and, depending on the quantity, size and the degree of these features are visible, they can greatly influence the overall cut the final rating. Diamond there may be an additional section or the lack of a plane, could be natural, could be the result of a circular contour imbalance, the result may cause aspects cannot be aligned, or diamond desktop into the octagonal. Diamond proportion related features related to the proportion, the overall cut diamond grade and the overall appearance of the effects may be stronger, and can noticeably change the price of the diamond. Features include a crown or pavilion, the Angle of the change, for example, waist thickness changes, or even waistline looks wavy, desktop may deviate from the middle of, or are not parallel to each other. All these characteristics, can greatly reduce the diamond cutting class. Very honored to provide by the well-known laboratory accreditation of diamond and jewelry.
