What grade should I look for when buying a diamond?

A diamond lasts forever. Choosing a satisfying diamond ring for a loved one is a very ceremonial thing before the couple enters the marriage hall. In addition to the meaning it represents, the quality of the diamond is also very important.

So how do you choose a diamond? In fact, like the 3C certificate of consumer electronics, diamonds also have 4C grades. To distinguish the quality of a diamond, it is mainly judged from four aspects: caratage, color, cut, and clarity.

So what is the best grade of diamond to choose? Let's find out together.

1. Diamond weight gradeDiamond weight is a critical factor in diamond quality, it directly determines the size of the diamond, the greater the weight of the diamond, the larger the diamond size, and the more visually eye-catching. Among them, carat is the common unit of weight for diamonds, 1 carat = 100 points = grams. According to industry experience, diamonds with a score of less than 15 are mainly used for setting, and the cut is the key consideration when selecting; If the weight of the diamond is more than 15 points, the color, cut and clarity of the diamond should be examined.

2. Diamond color gradeThe purer and more translucent a diamond's color, the better its quality. According to the diamond color grade, it is divided into ...... D, E, F, G, H, of which d is the best quality. In general, it is advisable to choose a diamond with a grade of H or higher.

3. Diamond cut gradeAs the only human factor that affects a diamond's quality, cut is often overlooked, and the actual diamond cut directly determines the brilliance and fire of a diamond. No matter how good a rough diamond is, if it is not cut with meticulous attention and the balance between brilliance and fire is not properly balanced, the beauty of the diamond cannot be shown. It is recommended to choose a diamond grade of 3EX or above, and if you have a limited budget, some indicators can be reduced to VG.

4. Diamond clarity grade: Under the condition that other grade indicators such as color and weight are sufficient, diamond clarity is not so important. In the process of selecting diamonds, the clarity of diamonds is not obvious to the naked eye, so it is recommended to choose VS2 or above diamonds according to the identification on the certificate.

You should buy a diamond with a grade of H or above, the higher the grade, the more transparent the color, the better the quality of the diamond, and you can also choose a diamond with a grade of VS2 or higher according to the bid in the certificate.

When buying a diamond, you should pay attention to the clarity grade of the diamond, this clarity is the most important distinguishing data of the diamond, the higher the clarity, the more expensive the diamond!

The purity grade should be the most important, and the diamond with the high purity grade has the highest economic value.

Purity. A high-purity diamond is small and has a high value, not just its weight.

For the mastery of ** information, in essence,It's a selection criterion, is the contrast of **. The comprehensive information of the diamond grade table is the basis for the professional information that must also be paid attention to. Of course, when the market changes, it is necessary to judge and choose the best because there is a significant difference.

The clear grading of all diamonds, as well as the comprehensive ** as the basis, has become the basis for consumers to understand more comprehensive information more easily, and provides a good choice for practical applications.

It is necessary to select and compare the actual grade of the diamondThe characteristics of the diamond grade table are that there must be more comprehensive information to grasp, that is, it is necessary to use the market and the quality and color of the diamond's products to conduct a comprehensive analysis. Because there is a 4C standard as the basic standard for diamond grading, it is necessary to reflect the rationality of Shibei's more professional objective judgment in the first information, which is to ensure that there is a good grading basis at the same time, and to have a more comprehensive evaluation of a specific piece of diamond as the basis, so as to achieve accurate ** and ensure that consumers can make convenient comparison and choice.

It is necessary to make a comprehensive comparative judgmentAs the basis, it is necessary to ensure that there is a reasonable grasp, clear analysis standards, and standardized grading evaluation and evaluation. Whether a polished diamond can achieve the effect of excellent quality assurance lies in the different levels of the four Cs, which have accurate grading standards and characteristics, so that its actual polarization can achieve a more accurate effect. The information of the diamond grade list should include more comprehensive content, ensure a better feeling, and have an objective, fair and reasonable guarantee, which is the key to let consumers understand the full information in the first information.

Be graded objectivelyTo ensure that there is a good sense of design, the main point to consider is to have a clear classification to ensure that the best is reasonable as the basic guarantee. In the relevant information content of the diamond grade table, there should be accurate evaluation standards, to reflect more comprehensive information, to make the grading standards of the grade can be excellent, objective and rational basis, is its most reasonable conditions, so that everyone who falls in love with diamonds can choose more cost-effective works.

The grade of diamonds can be analyzed from three aspects: color, clarity and cut, and these grades are generally divided according to the GIA standard, and the color of the rock can be divided according to the GIA standard: D, E, F, G, H, I, J, K, L, M, O-R, S-Z, and the color is reduced from front to back. Among them, the H color is the standard white, and the H color will become whiter and whiter, and it can only be felt in the contrast of different colors; Below the K color difference will have yellow, basically the yellow below the K color is already obvious, and it is not recommended to buy it as a diamond.

The division of diamond grade is divided into 5 grades, different material textures, and some of its values contain different ingredients.

Diamonds can be divided into different grades according to their orange color. High-quality diamonds are generally listed in the counter, and you can choose them through the introduction of the clerk.

Among the diamond grades, carat, color, cut, and clarity are the most important.

1. Weight: The weight of a diamond is a unit of weight, and one carat is equal to a gram. The greater the weight of the diamond, the more eye-catching and weighty it will be;

2. Color: In the grading environment of the special laboratory, the technicians compare the diamonds repeatedly, and they can be graded according to the color, and the whitest is D-grade colorless;

3. Clarity: When looking at a diamond, you can realize whether there are obvious flaws inside it, and the degree of flaws is very much affecting the ornamentation and value. Diamond clarity is divided into LC, VVS1, VVS2, VS1, VS2, SI1, SI2, P1, P2, and P3.

Diamonds that have been set are determined by the grades of Very Good, Very Good, Good, Better, and General;

4. Cut: The diamond cut determines the brilliance of the diamond. Diamond cuts are graded from high to low: ID, EX, VG, and G.

The 4Cs of a diamond are Caratage, Color, Clarity, and Cut.

Weight: Measured in carats, the heavier the weight, the better.

Color: Diamonds are graded from high (d) to low (z), with the higher the grade, the better.

Clarity: Clarity depends on the color, content, location, etc., of the diamond's inherent impurities.

Cut: The cut grade is divided into five grades: excellent to poor, with the higher the cut grade, the better.

The 4Cs of diamonds.

1. Grading of diamond color. Diamonds are first divided into colored diamonds and white diamonds, with the more precious and rare diamonds being red, pink, blue, green, and other colors. The most common are white and yellow diamonds.

The purer the diamond's color, the higher the transparency, the higher the **. Under magnification, diamonds come in a variety of colors. In the case of white diamonds, a 100-point color diamond is graded as D, 99-point Color E, and so on.

Up to J white diamonds are still referred to as naked-eye white diamonds, while K and below white diamonds are referred to as non-white diamonds. where d f is colorless, and g j is close to colorless.

2. Diamond clarity refers to the content of the diamond, which is the natural sign of the diamond itself. If there are fewer impurities in the diamond and the less conspicuous the location, the higher the quality of the diamond and vice versa. The cleanliness classes are FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, SI3, P I1, P i2, P I3.

3. The weight grade of a diamond is divided by the unit carat. One carat is equal to a gram, which is equal to 100 cents. In general, 1 carat is a dividing line, and diamonds under 1 carat are significantly lower than 1 carat.

All other things being equal, the greater the weight of the diamond, the higher the value of the diamond.

4. The cutting of diamonds is mainly the symmetry and balance of diamonds, and it is also the only human factor that affects the value of diamonds. The reason why a diamond has a sparkling side is mainly because of the cut diamond, which is the problem with diamond cutting. How you grade a diamond is also important in the cut.

The cut grade is high, and the diamond is beautiful. The grades of the cut are EX, VG, G, and P.
