2 thoughts on “Diamond symmetrical, what is the effect of polishing on diamonds? Diamond symmetry, the importance of polishing”

  1. Diamond polishing and symmetry are two important aspects in the cutting procedures. The level of polishing describes the smoothness of the diamond surface, and the symmetry level refers to the arrangement of the diamond surface.

    The polishing means that the light is reflected on the surface of the diamond unevenness, describing the smoothness of the diamond surface. The characteristic of polishing is that it is located on the surface, and there is no obvious penetration of 10x magnifying glass observations. Polishing is divided into Excellent (EX), Very Good (VG), FAIR (F), POOR (P) in classification standards. When the polishing is severe, it will not only greatly weaken the brightness of the diamond, but also affect the transparency of diamonds. The polishing quality is mainly related to the technique and carefulness of the diamond cutting process and the technology of the grinding artist.

    Themidmia refers to the horizontal symmetry of each part obtained by the diamond cutting and polishing, that is, the section arrangement and mutual angle. The same is the same as the ratio of evaluation two. If a diamond car worker and proportion are excellent, the symmetrical cutting will make the flash and fire more intense. Foreign certificates' evaluations of symmetry are more detailed. From high to low, there are IDEAL (ID), Excellent (EX), VERY Good (VG), FAIR (F), Poor (P).

  2. The following is the "" related information provided by OL Jewelry Network for your reference. I hope to solve the "" related issues for you. OL Jewelry Network is China's first female jewelry, diamond, diamond ring, wedding ring, wedding diamond ring, diamond ring. It is half cheaper than traditional jewelry shops. No matter how expensive. In the new GIA diamond cutting system, polishing and symmetry are used as a moisturizing degree, and even the important measurement specifications of cutting assessment. Do you know what kind of assessment specifications are polishing and symmetry? Is it bad for polishing and symmetry? If you are unfamiliar, please come with me. I will use the picture to post it to everyone to let everyone familiar with what kind of situation is not good. In the new American Gem Society (GIA) diamond cutting classification to standardize the round diamonds, the singing skills in this area-deeply entering the carefully polished diamonds, it can be seen that it finally plays an important role. The superiority and appearance planning of diamond surfaces. Click the picture to view the rhythm — bag inlaid series -white 18K gold (diamond) women's ring inlaid is below the metal side of the diamond with metal Prevent diamonds from falling off with the solids of precious metals. This is the most firm and most traditional inlay method. It shows the light of diamonds, light and restrained, and has a peaceful and dignified temperament. These two types of definition of fine polishing and symmetry have already some GIA foreign diamond classification systems? Since mid -1950, please refer to GIA diamond grading and diamond case. The hierarchical rail system, polishing and symmetry maintained the following are the specifications and door diameters of inspection for evaluation, and explain its role. This article expanded GIA's curriculum materials evaluation polishing and symmetry, describing application terms from GIA, completing evaluation indoors in the performance room, and proposing specific gaps, divided into two types of polishing and symmetry. "Polishing" refers to the surface state of the character diamond due to the polishing process (see Figure 2) or the cutting process of sore scar, which is often called "wear" (see Figure 3). There is no obvious penetration application 10x reduction mirror inspection. Polishing is divided into perfection in grading specifications, good, good, still, poor. "Symmetry" refers to diamonds with accurate shapes and symmetrical. Symmetry. The rating is also divided into 5 gear. It is perfect, good, good, still, the diamond cut in GIA, the diamonds that standardize the round light, to deal with GIA's D-TO-Z color color limitations and the clarity of FL To i3 Limitation, the tie rating of diamonds is closely related to the diamond. Those who meet the perfect cut rating level must be well or perfect whether polishing and symmetry must be good or perfect. • Follow the rating level well, and the polishing and symmetry must be the most. Above fair. FAIR cuts level, polishing and symmetry must reach FAIR. Poor cuts level, polishing and symmetry are POOR.
