The 4C grading of diamond refers to:
Coour
Capital
Cut cut
The source of weight cact
4c is the first of the first four English words. The letters are "C", so people's grades of diamonds are referred to as 4C grading or 4C evaluation. At present, it is a global general standard for diamond grading.
This customers may ask which "C" is more important when evaluating diamonds?
In fact, at the 4C assessment, each element is very important, which plays a key role in the final price of the diamond finished product. In the case of near other elements, the most important thing is the total amount of diamonds. The larger the diamonds, the thinner and the scarce. Therefore, determining the price of a diamond, which weighs more important position, is also the reason why customers are usually commonly seen to measure prices.
The we know about the above, we start to learn from
1, and weigh the weight of the weight:
1 carats are equal to 0.2 grams. Carat in Greece originated from "Kerate", refers to long -horn bean trees, a plant that has widely popularized from East Asia to the Middle East. Because its fruits are called nearly consistent weight, long -horn bean trees are used as heavy units for jewelry and precious metals. Once you determine the cutting, color, and clarity of diamonds, you can easily find diamonds with your budget.
The weight of diamonds is very important in diamond grading. The weight of the diamond is measured with carats. The word carat comes from a seed called "small horn tree". Because the weight of this seed has an amazing consistency, each seed is a carat, so it is used to weigh the weight of diamonds in ancient times. The current national standard is 1CT = 0.2G, one carat is equal to one hundred points, for example: a 25 -point diamond can be recorded as 0.25 carats. Diamonds of the same quality, the larger the weight, the more precious.
The weight or size of the diamond is measured by carat (CT). 1CT = 0.2 g, and 1CT = 100 (PT) (or equivalent to 200 mg (mg)). The electronic balance with a accuracy of 0.0001CT is called accurate diamond weight. Mechanical balance can be refined to 0.001ct. The international gem quality unit, the finished diamond requires accurate to two digits after the decimal point, the third place after the cam value point is the third place every nine. Entry, other negligibles.
Summary: Start with 25 points or more, you can buy more than 30 points for money, and more rich can be more than 50 points.
2, cutting Cut
The various optical effects of the diamond are determined by the shape of the diamond and the angle between each surface. From the 4C grading below, we can also see that any one -cut evaluation factors are not standard, which will affect the bright and gorgeous diamonds to varying degrees.
If the countertop is too small, it will greatly weaken the brightness of the diamond;
If cut work, the various optical effects of diamonds cannot be fully achieved, and the brightness of diamonds and various optical effects such as fire color will decline.

The clarity refers to the cleanliness of the diamond, that is, the number of flaws. The defects that affect diamond clarity are generally divided into two parts, namely internal defects and surface flaws (also often referred to as external flaws).
The clarity of diamonds is divided into five levels:
1. There are no flaws under the mirror, that is, LC or IF level. Refers to no flaws inside or surface of the diamonds under 10 times the large mirror.
2. Extreme micro flaw, that is, VVS level. And subdivided into two subunits: VVS1 and VVS2. VVS1 refers to extremely small flaws that are also difficult to observe under 10 times large mirror; VVS2 is extremely small flaws that are difficult to observe under 10 times large mirror.
3. Micro flaw level, that is, VS level, is also distinguished as VS1 and VS2. VS1 refers to small flaws that are difficult to observe under 10 times large mirror; VS2 is a small flaw that is more likely to observe under 10 times large mirror.
4. Infertility level, that is, SI level, is also distinguished as SL1 and SL2. SL means that it is easy to observe the flaws in a 10 -fold mirror; SL2 means that the flaws are easy to see with 10 times large mirror, but the naked eye still does not see its flaws.
5. heavy flaw level, or flower level, that is, P1, P2, P3, three sub -levels. P1 refers to observing from the crown, and the naked eye can be seen in the naked eye; P2 refers to the fleshy eye to observe very obvious flaws; P3 is a very obvious flaw that the naked eye is easy to observe.
On the certificate, the flaws of diamonds are generally expressed, and the internal defects are represented by red, and surface defects are represented by green.
The impact of diamond clarity on diamond prices is also significant. When the diamond weight is the same, the better the diamonds of the color grade, the greater the price difference caused by the difference in the level of the clarity.
Such standards are GIA diamond clarity standards. The meaning and differences represent the following:
vs1: Very Slightly Included,
n
vs2: Very Slightly Included, there are very small connotations, it is difficult to see (the naked eye is not visible)
vvs1: very very slightely included, there are very small connotations, it is difficult to see (the naked eye is not visible)
vvs2: very very Slightly Included, there are very small connotations, it is difficult to see (the naked eye is not visible)
other symbols in the standard:
fl
n flashless
The flawless
if

si1

The small connotation, extremely difficult to see (the naked eye is not visible)
nsi2

has small connotation, it is difficult to see (the naked eye is not visible)
ni1

r r r r r
The connotation (visible to the naked eye)
i2

There is no difference between the naked eye
The price of the price is given downstairs
is all good -looking your own needs
buy VVS1 to buy a larger money to buy a VS
In the pursuit of perfection and buy if
The ones upstairs answered very comprehensive. It is important to be familiar with 4C
. If you use suggestions, you do n’t need to buy too high level, because the naked eye cannot be distinguished, but the price is a lot. It's okay, the color H, i-j is fine
