Cutting refers to the method of cutting the gem. Different gems have different cuts, and different cuts can also be used for the same gem.
. For example, emerald is cut by emerald according to its nature, and
The diamond -type cutting of diamonds can better reflect its fire color and brightness.
It if the diamond wants to reflect the clarity and color, it is also possible to cut the emerald.
The appearance of cutting out and cutting out becomes a cargo type, and there can be different types of crafts, because the type we see now has evolved from ancient times, so there have been many, many, and since ancient times to the present to the present Type, but now that technology is developed, knowing how light is going on and what impact it has on gems, so it has adopted a more common and reflected effect of gemstones.
The gold, platinum, silver, platinum are metal, and they cannot be used in cutting. Metals are used to inlay gems, just like if you have a gem ring, the gem is to see cutting, and the metal is the one wrapped outside the gem.
It because the metal is ductantly, it can be made into different shapes, so there is a ring, pendant, chain, etc.
For cutting level Cut the level.
The diamond grading becomes 4C grading: color grading, clarity classification, cutting classification, carat division
The cutting grades in the diamond belong to one of the 4C grading.
The we can classify diamonds according to different levels. The higher the level, the more expensive.
It like diamonds, it is routine to be 57-58 noodles. Unless it is dozens of carat diamonds, you need to design it specifically for it.
The following is the standard of copying the encyclopedia 4C. What is the difference between LZ to see?
It the value of diamonds, 4C parameters can be identified, except for color diamonds.
carat weight (cact)
diamond weight is calculated in carat (also known as card). 1 carat = 200 mg = 0.2 grams. One carat is divided into one hundred copies, each called one point. 0.75 carats are also called 75 points, and 0.02 carats are 2 points. Under other conditions, as the diamond weight increases, the value of the value is increased geometrically; diamonds with the same weight will be far from the difference in color, clarity, and cutting. In each different size and shape, you can find a high -quality diamond. The most important thing is to find a diamond that is suitable and style that makes you like. You might as well try in the jewelry shop. When it looks right and feels right, that one should be yours.
Clarity
diamond crystals in the mantle magma deep in the deep earth. The environment is complex, the composition is diverse, the temperature and pressure are extremely high. Contains various debris or flaws. The color, how much, size, and position distribution of these inside contains the effects of different degrees on diamond clarity. The clarity of diamonds usually uses a 10 -fold mirror to classify the clarity level of unsolved diamond inside, surface flaws, and its impact on the degree of influence on gloriousness. , SI1, SI2, P1, P2, P3 total 10 levels. The inlaid diamonds are divided into excellent, good, good, better, generally 5 levels. P -level diamonds are also called Class I diamonds. The following P -level diamonds are generally not used as gems, so they are generally only divided into P levels, and no P1P2P3 is no longer divided.
color (color)
The diamonds have many natural colors, from precious colorless (after cutting white), rare light blue, pink to common yellowing. The more transparent, the more white can penetrate, and the more colorful after refraction and color. Diamond color grading is in the hierarchical environment of a professional laboratory, and technicians will be determined by repeated contrast between the hierarchical diamond to the standard color than the color stone. The whitening diamonds are set as D -episodes (that is, start with Diamond's first letters). The color of diamonds is divided into 11 levels, in turn: D, E, F, G, H, I, J, K, L, M, N.
Cuts
The cutting of diamonds refers to the accuracy of its cutting ratio and the perfection after the completion. Good cuts should be as good as possible to reflect the brightness and fire of diamonds as possible, and try to maintain the weight of the rough. GIA's cutting level from high to low is divided into ID (standard), EX (excellent), VG (good) G (good) G (good), Chinese national inspection is divided into: EX (excellent), VG (very good), G (g Okay) In China, ordinary people generally look at the size of the diamond. It is actually unscientific. Because China is more popular. Therefore, the more popular concept is high -quality glory diamonds. High -quality glory diamonds generally grasp the three principles of 4C: clarity, color (color), and cut (CUT), and the three standards must meet certain standards at the same time.
ps: I wrote it myself. If I do n’t understand, I can ask me. I think I can remember to give points! hey-hey!
Diamond cutting classification
Whow we judge the diamond cut? What are the levels of diamond cutting?
The exceed of diamond cutting:
The standards that can only achieve only 3%of first -class high -quality diamonds. This cut makes the diamond reflect almost all the lights entering the diamond. An elegant and outstanding cut.
The level of diamond cutting is very easy to cut (Very Good):
The represents about 15%of diamond cutting. It can reflect the light of diamonds and cut standards, but the price is slightly lower.
This of diamond cutting level (Good):
The represents about 25%of diamond cutting. It is the diamond reflected most of the light that enters the diamond. It is much cheaper than VG.
This Diamond cutting level (POOR):
This containing all diamonds that do not meet the standard of general cutting. The edge or bottom is relieved. We do not provide such inferior diamonds.

The width and depth of diamonds have a biggest impact on the firecolor of the diamond.
This is too shallow: The light is lifted from the bottom and the brightness of the diamond is damaged.
The cutting is too deep: the light is easy to escape from the pavilion, the brightness of the diamond is damaged, and the luster of luster becomes dim.
The width ratio: The percentage of the width of the crown's tablet is relative to the average diameter of the waist; Percentage of diameter;
The pavilion depth ratio: The percentage of the depth of the pavilion is relatively low waist diameter;
The bottom ratio: the percentage of the maximum diameter of the bottom is relatively diameter of the waist; The percentage of the vertical distance from the tip of the tip of the part at the end of the part;
crown angle (°): the angle between the main face of the crown and the level of the waist circumference;
Round diamonds are cut, and red and blue gems are cut.
The diamond cutting is divided into 3EX 3VG 3G.
If there is still a problem, the building, you can Baidu Hi me. Hope to help you ~!
gold, platinum gold jewelry.
There is no
The cutting class only for standard circular diamond -type diamonds
