5 thoughts on “How to look at the good or bad of the diamond ring and polishing, how to distinguish the level”

If you use the naked eye to see the quality of the diamond, because you need to know a good understanding of this diamond ring. Many of our friends do not know how to distinguish the good or bad of diamonds. Some are based on the issuance of the identification certificate, and some are based on the seller's explanation. So can our naked eye cannot distinguish the good or bad? In fact, the good or bad of cutting can be judged with our most intuitive visual effects. How can we see the quality of diamond cutting? The following places that need to be paid attention to can find good or bad as long as you look at it carefully. 1. Face -faced The countertop and small aspect of diamonds are straight and unpopular. There is no flexion. The reflection image occurs on the countertop with straight edges. The drilling diamonds will have the effect of flexion on the countertop. . The edges and corners The edges and corners of the diamond are straight and sharp. Small face -to -face also strictly intersects with a edge line. The imitation similar to diamonds, due to the low hardness and poor cutting, often the edges and corners are smooth. . The waistline is a standard round diamond diamond. The waist circumference is usually not polished after rough grinding. This non -smooth waist circumference is called the "glycation" effect. The "glycation" waist is a typical cutting characteristics of diamonds, expressing the phenomenon of prestigious waxy reflection. Most imitation products have polished waist circumference, and the grinding line can be seen under a microscope. 4. Polite marks This is a small series of almost near -parallel lines. Due to the high hardness of the diamond, it can form a good polishing. Polish marks, but sometimes polishing is not exquisite, small polishing marks are visible. Stime points of observation can allow us to distinguish the good or bad of diamond cutting by themselves. There is such a flash of fire.
Good The cutting of diamonds: EX (top) VG (good) g (good) g (good) mainly observed the following points to evaluate: Taiwan width ratio, pavilion deep ratio, crown, crown, crown, The corner and the corner of the pavilion, the thickness of the waist, the polishing pattern and the extra face. The best cutting ratio of diamonds is: 53%-66%of the platform width, 41.5%-45%of the pavilion depth, 31.7-37.7. it is good.
Although your points are very tempting, I believe that even if I tell you the standard answer, you may not be able to understand it ~~~ This kind of professional knowledge is very professional, and knowledge is accumulated. Can be solved!
The original poster is good The cutting of the diamond is divided into three levels: EX (top) VG (good) g (good) g (good) M main observation of the following points to evaluate: Taiwan width ratio, pavilion deep ratio, comparison Crown corners and pavilion corners, waist bond thickness, polishing patterns and extra face. The best cutting ratio of diamonds is: 53%-66%of the platform width, 41.5%-45%of the pavilion depth, 31.7-37.7. it is good.
