The grade of the diamond, what is the grade of the diamond

A diamond's 4C grade is based on the diamond's 4C criteria.

There are (colour, colour, weight, carat, cut, clarity, )

Clarity: Usually use a 10x magnifying glass 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

Weight: The weight of a diamond is measured in carats, one carat = 100 cents = grams.

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

Generally, it is more appropriate to propose marriage with 50 points to one carat, provided that you set a budget first, 50 points are generally 1w up and down, one carat is about 3w, generally only sincere will send Darry Ring, each boy with ID card lifelong order only one, meaning "the only true love in life" This kind of love is worthy of a girl to marry you.

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.

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. A D diamond is the lowest grade diamond with more blemishes, darker color, and lower**; E diamonds have fewer blemishes, brighter color, and higher**; F diamonds have very few blemishes, brighter color, and higher quality; G diamonds have very few blemishes, are brighter in color, and are the highest grade diamonds.

As a result, diamonds are graded from lowest to highest in order of D, E, F and G.

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 dear. The grades of diamonds are LC, VVS, VS, SI, P Diamond ring grades are divided into 5 grades, and diamond ring grades from high to low are: LC, VVS, VS, SI, P, and this only refers to the clarity grade of the diamond ring grade.

Pick a diamond ring must know: how to distinguish the grade of a diamond ring When distinguishing the grade of a diamond ring, you should pay attention to the grade of the diamond that has been set in these aspects: clarity:

From high to low, there are five grades: LC, VVS, VS, SI, and P, and LC grades are generally rare. Color:

From high to low, there are five grades: extremely white, excellent white, white, light yellow and white, and light yellow, which are generally white, light yellow and white. Weight ridge height:

The unit of weight is carat (ct), 1 carat = gram = 100 points, generally more than 10 points to indicate the diamond grade. Cut: Cut is generally not evaluated for diamonds.

The presence or strength of a diamond's fluorescence is not related to the diamond's grade, but is only one of the pieces of evidence to ensure that the report corresponds to the diamond. However, most consumers still don't know much about the grade of diamond rings, such as "how to choose the right diamond jewelry", "how to distinguish between good and bad diamonds", and so on. Some unscrupulous merchants also take advantage of people's ignorance of diamonds, and often exaggerate the grade of diamond rings when they are consulted, so as to mislead consumers and cause consumers to suffer unnecessary losses.

When consumers ask what grade of diamond it is, many merchants use vague concepts such as "excellent grade" and "high quality". In the four sung cherry blossom standard of its cherry blossom ruler diamond, the weight is expressed in carats; Clarity is.
