What are the grades of diamonds and what are the grades of diamonds

The diamond's grade is based on the diamond's 4Cs, which are weight, color, clarity, and cut.

Weight: The weight of the diamond is a very important and basic factor among the four factors that affect the value of the diamond, the larger the weight of the diamond, the rarer, so the value will also rise with its rarity, the weight of the diamond is measured in carats, one carat = 100 points = grams. Color:

The most transparent and colorless white diamonds are graded as D, in descending order: D, E, F, G, H, I, J, K, L, M, N, ,..z。

Clarity: Usually 10x magnifying glass is used to observe the inside and exterior of the diamond, and the diamond clarity grade is subdivided into FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, L1, L2, L3. Cut:

From the perfect EX cut, down to VG, G, F, P. There are multiple combinations of diamond grades, but there is only one true love like DR, which is also one of the meanings of diamonds that can be used as eternal tokens in love.

Diamond 4C standard: 1 color (collur) 2 clarity (clarity) 3 cut (cut) 4 carat

1 Color: Diamonds are graded in the order of the letters D to N, indicating that they are completely colorless to light yellow, with complete colorless being the rarest. d is the best. In jewelry, it is common to see two letters such as f-g, i-j, etc. together.

2 Clarity: Clarity grading is seen through a 10x magnifying glass. It is usually divided into 10 levels. It is: LC vvs1 vvs2 vs1 vs2 si1 si2 p1 p2 p3

3 Cut: The beauty of a diamond comes from three elements, brilliance, fire, and sparkle, and only a good cut can achieve a balance between these three elements, 4 carats: The diamond weight is calculated in carats, one carat is 100 points, and the larger the carat weight, the rarer.

The more precious, the higher the value, and those below 100 are usually called cents, such as half a carat, and people usually call them 50 cents.

If you want to buy a diamond ring, you can consider buying loose diamonds if you want to be more affordable.

Diamonds are graded according to their color

Diamond color can be divided into 23 grades, such as D, E, F, G, H, I, and J, from colorless to yellow or yellowish-brown.

Grade D: Grade D is the highest grade in a diamond's color grade, which means that the diamond is completely transparent, and this type of diamond is extremely rare, so it is very expensive.

Grade E: This type of diamond is close to colorless under 10x magnification, and only diamond identification experts can detect a small amount of pigment with professional equipment, which is also a relatively rare diamond.

F: This grade is also close to colorless in color, and it is still a high-quality diamond.

G-H Grade: G-H diamonds do not show any color when viewed directly with the naked eye, but when they are compared with diamonds with better color, they can be seen with a slight change in color.

I-J: Diamonds of the I-J grade have begun to turn yellow in color, and a slight color can be seen when viewed closely with the naked eye.

K-M grade: This type of diamond color is more yellow, consumers can see a slight yellow color when they look closely, and it is not recommended to buy. M-Z grade: The internal yellow color of the diamond after M grade is already obvious, and the diamond quality is relatively poor, which is not enough to buy.

Diamonds are graded according to their clarity.

The clarity of the diamond, the size of the blemishes and inclusions contained on the surface and within the diamond. The clarity grade can be divided into 11 grades from high to low, such as FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, I1, I2, and I3.

Flawless (FL): FL is the most perfect grade for diamond clarity, and this type of diamond is very rare when viewed under 10x magnification, without any inclusions or blemishes.

Internally Flawless (IF): An IF diamond has no inclusions, but has some minor blemishes on the surface that can be removed by polishing.

Very Slightly Included (VVS): VVS levels are further divided into VVS1 and VVS2. These diamonds can be seen under 10x magnification with tiny imperfections inside, but they are extremely slight and not easily noticeable.

Slightly Included (VS): VS grade is divided into VS1 and VS2 grades, VS grade diamonds are observed under 10x magnification, and the flaws of the diamond are visible, but very small.

Slightly Included (SI): The SI grade is divided into two grades, SI1 and SI2, and these diamonds can be seen under 10x magnification and have clearly visible imperfections.

Included (I): This type of diamond is generally not recommended because the imperfections are already obvious and can be clearly seen under 10x magnification, even with the naked eye.

The diamond grades are as follows:

Grade D: Completely colorless. The highest color grade, extremely rare.

Grade E: Colorless. Only gem graders are able to detect trace amounts of color. It is a very rare diamond.

Grade F: Colorless. A small amount of color can only be detected by jewelry experts, but it is still considered colorless. It is a high-quality diamond.

G—H grade: close to colorless. When compared to a higher color grade diamond, there is a slight color. But diamonds of this color grade are still highly valued.

Grade I—J: Nearly colorless. Slight colors can be detected. The value is higher.

K-M grade: darker color, poor fire.

N-Z grade: darker color, poor fire.

How to distinguish diamonds from grades

First, color. The color of diamonds is divided into two categories: colorless and colored, among which, the more transparent and colorless the colorless series, the better its quality, and its grade ranges from Defghi to XYZ.

Second, weight. Diamond weight is calculated in carats, 1 carat = gram = 100 points, and carat is 45 points. All else being equal, the greater the weight of the diamond, the higher its value.

Third, clarity. A diamond's clarity is the number of inclusions it has, and it is graded from FL IF (internally flawless) to I (blemishesive).

Fourth, cut. Diamond cut is the second life of a diamond, and the value of a diamond with the right cut ratio will naturally increase, and its grade is ID (eight hearts and eight arrows), EX (excellent), VG (very good), G (good).

Diamonds are graded according to the 4Cs, which are four aspects: color, cut, clarity and weight. The color grade of diamonds is divided into 23 grades, such as D, E, F, G, H, I, J, etc., the color ranges from transparent to yellow, the more transparent the color, the higher the grade, the highest grade is D diamond, and the lowest grade is Z diamond.

The cut of the diamond refers to the cutting process, which can be divided into 5 grades: EX, VG, GD, F, and P, in the case of the same other 3C standards, the more perfect the cut of the diamond, the smoother the line, the higher the grade, and the highest grade of the diamond is the EX diamond, that is, the perfect cut diamond.

Diamond buying tips

Before buying diamonds and diamond jewelry, you must budget for your purchase in advance, so that you can do what you can afford. If you are really limited in budget but want to buy a larger diamond, it is recommended that you can choose diamond jewelry with poor clarity but high color.

For many jewelry stores or diamond sales stores, it is common to use festivals or celebrations to do some **discount** activities. Therefore, consumers may wish to pay more attention to advertisements in newspapers and magazines before buying diamonds, so as to help choose the best time to buy diamond jewelry.

1. Divided by weight: In the case of the same color, clarity and cut grade of the diamond, the greater the weight of the diamond, the higher the grade, and the higher the value.

2. According to the cut: from high to low, it can be divided into five grades: excellent, very good, good, fair and poor.

3. According to clarity: from FL IF (flawless and flawless inside) to I (flawed). I clarity means that the contents are visually discernible to the naked eye.

4. Divided by color: The color of diamonds is divided into colorless and colored. Colorless diamonds range from D (transparent and colorless, i.e. from the first letter of diamond) to Z (yellow). Coloured diamonds are not graded.

Diamonds:

Diamond refers to polished diamond, which is a natural mineral that is the rough of diamonds. To put it simply, diamond is an elemental crystal composed of carbon that is formed under high pressure and high temperature conditions in the deep part of the earth. Beautiful, rare, and a symbol of love and fidelity, diamonds represent eternal love.

Identification Criteria:

There are four main criteria for measuring the rarity of a diamond, namely weight, clarity, colour and cut, which is commonly known as the 4Cs. This standard was established by the GIA (Gemological Institute of America) and is currently the most mainstream diamond evaluation standard in the world, including China.

Hello, it is a pleasure to serve you and give you the following answer: Diamonds are generally graded into 4 grades, namely D, E, F and G. D diamonds are the lowest grade diamonds with lower clarity, lighter color, and lower grades; Grade E diamonds have higher clarity and darker color, and are also higher**; F diamonds have extremely high clarity and very dark color, and ** are also extremely high; The G diamond is extremely clear and dark, and it is also extremely high, making it the highest grade diamond.

Therefore, diamonds are graded from lowest to highest in order of D, E, F and G, and ** also increase from low to high.
