Reference price: diamond weight: 0.4 carats, color: E, clarity: SI1, cutting: ex, polishing: ex, symmetrical: EX 6266 (± 300 yuan)
to recognize the international standard of evaluating diamond -4C. 4C refers to color, clarity, carat weight, and car worker (CUT).
The color colors of color color
most of the diamonds are white, which can be divided into "colorless transparency" to "close colorless" and "light" and "light" yellow". The color level is based on the ISO international standard organization, which starts from "D" color to "Z". The color is D, E, and f, also known as transparent colorlessness, which is extremely precious and rare. The difference between them depends on experts to distinguish them carefully. What is more common is that the color is G to L, which is also called close to colorless. Experts will be easier to distinguish, but it is difficult for ordinary people to distinguish, and it is even more difficult to detect if it is inlaid on jewelry. The color is below M, also known as pale yellow. Most people may be distinguished, but the price is obviously much cheaper.
The diamonds still have other colors, called color diamonds, Fancy Coloured Diamond. It can be yellow, pink, blue, green, red, black, ever -changing, but very rare and high value.
Clarity -the unique recognition of each diamond
each diamond is unique, and it contains the inherent internal contents such as: minerals or unscrupulousization Carbon materials, etc., are like natural birthmarks, and the number, size, shape, and color of these inside will determine the clarity and uniqueness of a diamond. In fact, most diamonds cannot be identified by the naked eye. The less the diamond contains, the more light reflects, and the diamond will double the brilliance. According to the ISO International Standard Organization, the identification clarity should be carried out under 10 times, and its level is as follows:
fl / if perfection / internal flawless nvvs1 / VVS2 extremely light flaws (the experts must also find it carefully)
vs1 / vs2 mild flaws (the expert is more likely to find)
si1 / si2 micro defect (ordinary people may find it to find )
i1 / i2 / i3 has defects
In all summary, diamonds of VVS or above are rare. VS or SI is invisible to the naked eye, but the price is much cheaper, and many people buy it. As for level I1 -I3, of course, the price is much lower. If it is bright enough, it can also give you a very beautiful effect.
The weight of carat weight. The weight and size of a diamond
The diamond weight is calculated in carats, or it is used to the 'card', 1 carat is equal to 100 copies, one 0.5 carats of 0.5 carats Diamonds can be written in 50 copies. 1 card is equal to 0.2 grams, which means that 1 gram is equal to 5 cards. The larger the diamond, the less the more it is. But how rare is there? According to statistics, it is necessary to excavate 250 tons of land before it can produce diamond stone embryos with 1 card. Therefore, weight has a great impact on the value of diamonds! Large diamonds are relatively rare, so they are more precious. Even though 4C is the easiest to master the weight of carats, even if two diamonds of the same carat weight will be in the court due to different color, clarity and car workers. For those who first purchase diamonds, try to start with the size of the choice of diamonds.
The car worker CUT display light, flashing and fire
nature determines the color, clarity and weight of a diamond, but a pair of exquisite crafts can be fully prominent Its fire reflects the shiny light of diamonds. In addition to the shape, the car worker also includes angle, proportion, symmetry, polishing, and so on. A detailed diamond of a car can distribute the dazzling dazzling and fire in any shape; when the diamond cutting ratio is appropriate, the light is like a mirror reflection. Glory that is brilliant. Excessive or shallow diamonds will cause light to flow away from the bottom, but lose light. Therefore, the value of diamonds that is appropriately cut is naturally higher. When buying, why not appreciate the light to reflect the dance in the diamond, exuding the color like a rainbow!
The rings are divided into PD950 PT950 and what 750 (I forgot the English in front, I studied 950) PT950 is platinum (one is "platinum" and "white K gold" Unclear, that is, white K gold as platinum. In fact, platinum is essentially different from white K gold. Platinum, English name is Platinum, is abbreviated as PT, only platinum can be played on PT marks. Platinum can be said to be the most in the world. The rare jewelry is precious metal, which is mainly produced in South Africa and Russia. And "white K gold", or "K platinum", is actually a K gold made from gold and other white alloys. Among them, the gold content is generally 75 %. It is white because of other white metal elements. The English name of the white K gold is Whitegold, the abbreviation is WG, the white K gold cannot be played by PT marks, "platinum" is not "platinum". Some people read platinum as platinum, especially the old generation often confuses "platinum" with "white K gold", but it is easy to distinguish by relying on English pronunciation.) , I personally think that the PD950 is fine, PT950, PT950, PT950 Each gram of PD950 is about 200 yuan, PT is the most expensive

The price of this level of diamonds is about 4500 plus the PT950 ring, and the
is about 7000.
It's really a little expensive
