Regarding the cutting of diamonds, it is generally divided into eight important cuts. 1, standard round diamond -type cut (Round Brilliant Cut) : Round The diamond -loading type is generally standard round diamond type. There are 58 small noodles in this type. The plane on the top is called the table, the largest part of the diameter is the waist circumference, the waist circumference is the crown part, and the lower waist circumference is the pavilion. 1919 The Marcel Tolkowsky (Marcel Tolkowsky) draws a round diamond -cut style through optical computing, which can reflect the firecolor and gloss. A total of 58 faces, the small noodles, and the bottom of the sharp face, there is no sharp bottom for small diamonds below 25 points, and a total of 57 face -to -face, thus laid the foundation for standard round diamond -type cutting. But a four -pointed rough, cutting the weight the most at this ratio. So this can only be used as a reference. The cutting ratio of Toccivusky is: Average waist circumference diameter: 100%countertop: 53.0%crown height: 16.2%pavilion height 43.1%crown angle: 34 degrees 30 minutes Pavilion angle: 40 degrees 45 minutes. Lile the foundation of the ideal cut of diamonds. The cutting ratio of different regions is different. The Tosovsky cutting is also called the United States, and other German -oriented, European crafts, etc. 2, oval brilliant cut (oval brilliant) : oval effect. Its rough retention rate can reach 50%to 60%, which is suitable for diamond rough with long octopus. Also because it can retain the high quality of diamonds, it is mostly used for many re -cut ancient diamonds The outline requirements of the shape: shoulder symmetry
3 Brilliant cut) shape: pear -shaped cutting: bright/brilliant Origin: 17th century is also known as tear cut or pendloque (pendloque CUT) has a collar effect. The pear -shaped cutting was very popular during Louis XIV, France, and nearly 20%of the famous diamonds in history used this cut, including the world's largest diamonds: Cullinan 1. Such cutting is suitable for diamond rough with damage or defects on the corners of one end. Pay attention to the protection of the sharp corners when inlaid. Oblaivism contour requirements: symmetrical wings on both sides, no defects on the sharp corners 4, marquise brilliant cut (marquise brilliant) n Origin: In the 17th century, the Dharma Louis XIV period is also translated as a horse -shaped cut or a boat -shaped work. The ends of this cut diamonds are sharp -cut, shaped like a nucleus, hence the name. There is a collar effect. This rough retention rate is low, and its features are at the sharp corners at the end of the two ends. The parcels here can be well covered up and the glitter at the sharp corner is extremely high. Pay attention to the protection of sharp corners when inlay. The appearance requirements: spike symmetry, no defects 5, square cut (Square Brilliant) R N Origin: In the middle of the last century, Belgian craftsman was invented. This kind of cutting was continuously improved and a series of improved forms were derived. The as a improved form of step -type cutting, it can also be classified as mixed -type cutting. The square cutting has a square or rectangular shape, usually with 76 aspects. But there are also 61, 101 aspects or 144 face -to -face. Among them, 101 face -to -face square bright cuts are cut for the registered patent of E.F.D. Diamond Company, that is, the princess. The square cutting can be diversified, but the crown is generally shallow, the countertop is large, and the pavilion is deeper. This rough retention rate is higher than other bright cutting methods, but it is not applicable to the lighter drill billet. The brightness and flicker generated by the face and pavilion to reduce the visibility of the parcel, and slightly "improve" the color level of the diamond, and the same weight square cut diamond and circular cut diamond phase phase Compared with about 15%larger shape. The square shape is suitable for seamless inlaids for tightly arranged diamonds. This is unable to do with other shapes of diamonds, but the sharp corners need to be protected when inlay.
6, Heart Brilliant Cut : Heart shape R n The diamond shape is composed of two wing petals, the grooves in the middle, and the sharp corners at the bottom, like a heart shape. The heart -shaped cutting diamonds are all shallow, suitable for irregular shapes and flat diamond rough, the parcel in the original groove can be removed to improve the diamond clarity, but this kind of cutting work The retention rate of rough stones is low. The appearance evaluation of heart -shaped diamonds mainly focuses on the symmetry and full shape of the wings on both sides. 7. Emerald cut (EMERALD CUT) : Rectangular Cutting work: staircase type Origin: Ancient n Typical step -type cutting method, derivative processing method, All cut surfaces are parallel or perpendicular to the square waist circumference of diamonds. The shape is rectangular. Because it is commonly used for the processing of gem emeralds, it is named. The diamond -cut diamonds with emeralds are more difficult to cover the wrap, which is suitable for diamond rough with high clarity, rectangular, slightly damaged or wrapped in the corner. Its rough retention rate can reach 60%to 70% High. The appearance requirements: Pay attention to the size and line of the four corners and the lines must be strictly parallel.
8, appearance: rectangular Radiant Cut (Radiant) In 1977, the craftsman hoped that the elegant appearance and roundness of the comprehensive emerald's green work created this cut. radiant has a rectangular shape and the four corners of the cut. It takes into account the retention rate and easy -to -match shape of the emerald's high cutting. It also has an excellent light performance like a round and splendid cut. radiant cutting is suitable for slightly rectangular. There are rough stones with damage and defects in the four corners. The retention rate of rough stones is high.
Diamonds are very hard items in the world. With the brilliantness and flashing of themselves, they are loved by the masses, especially the diamond ring created by it. It's very popular. Everyone likes diamonds, but I do n’t know how the diamond quality is good or bad. Some people may know that diamonds in 4C are cut, but professional terms are not understood by everyone, so how to introduce the cutting of diamonds is more easy to understand? R? R? nOn how to introduce the cutting of diamond The diamond 4C includes the color, clarity, cutting, and carat of diamonds. Of these 4 factors, only cutting is directly affected by human factors. We often see different shapes. Diamonds, which are formed by cutting and processing, and the exceptions of cutting will directly affect the fire and flash of diamonds. Without a good processing, diamonds will not be as glittering as we see. In the jewelry industry, everyone cuts diamonds as the second life of diamonds. This such an important factor, how to distinguish the quality of quality through it? First of all, understand the level of diamond cutting, it is divided into five levels, namely: Omi how to introduce the cutting of diamond n Ideal cut (Excellent), this cut makes diamonds almost reflect all the light that enters the diamond. Simply put, it is very outstanding. Very good work (Very Good): Compared to the ideal cut, it will be worse, but it is also perfect. Pood: Diamond reflects most of the light inside the diamond, which is a optional level of diamond ring. A general cutting (FAIR): Diamonds are still high -quality, but it is not easy to cut. Poor: This low -level diamond, whether it is carving or the light reflex in the diamond, does not meet the level of jewelry production. Therefore, there is almost no jewelry jewelry. This is very low. Cut the diamond cut level to create jewelry. It how to introduce the cutting of the diamond The content of the related content of the diamond cutting is introduced here today. Do you immediately know that when you buy diamond jewelry, which one should be better for diamond cutting level? You know how to introduce the cutting of diamonds. You have to learn to pass it to the next person who does not understand and learn from each other, so that you will understand the diamond more and more, and the choice of diamond jewelry is becoming more and more smooth.
