1. From the perspective of color From the perspective of color, diamonds include white diamonds, red diamonds, blue diamonds, green diamonds, etc. Among them, white diamonds are common diamond jewelry inlaid diamonds. Love: Red diamonds are composed of pink to bright red. The main place of origin is Australia. It is a relatively rare variety: blue diamonds mainly have dark blue. This color diamond is more special. It contains boron with conductive performance. element.
2, from the level of level
If divided from the level of level, how many diamonds are there? There may be thousands of types, because from the division of weight, there are 10 points, 20 points, 50 points, one carat, etc. from the perspective of color D-z division. It from the perspective of clarity: FI, IF, etc.: From the perspective of cutting, there are EX, VG, G, FAIR, POOR, etc. from the perspective of cutting. If these factors are arranged and combined, there will be many types of types. Pucting data The color of the diamond includes three major series: Kaipu series: including colorless, light yellow to yellow diamonds; brown series: including brown diamonds of different strengths; color series: including pink, purple, golden, blue, green and other diamonds. Most of the gem-grade diamonds belong to the colorless-light yellow series in the Kaipu series. This series of diamonds are also the most varieties purchased by consumers daily. Among them The more precious, the higher the value. The color level of the diamond D level: completely colorless. The highest color level is very rare. e grade: colorless. Only expert jewelers can detect minimal pornography. It belongs to rare diamonds. F level: colorless. Only expert -level jewelers can notice the subtle color, but they can still be regarded as "colorless" and belong to high -quality diamonds. g-H level: close to colorless. The color can be visible when compared with higher -level diamonds, but it is extremely cost -effective. i-j: Close to colorless. The color is slightly visible, and the cost -effective is superb. k-m: The color can be visible. N-Z level: color visibility. Reference information Source: Baidu Encyclopedia-King Kong Stone
I. Typei diamonds can be divided into IA and IB type according to the amount of nitrogen content and nitrogen.
(1). AIA diamonds: more nitrogen contains (0.1-0.3%), nitrogen exists in diamonds in small pieces. Under ultraviolet light, blue fluorescent (sometimes green, yellow, red and other colors). No electricity. 98 % of natural diamonds.
(2) .ib diamonds: less nitrogen containing, presence of decentralized existence. Fluorescence is the same as IA. No electricity. There are very few natural diamonds, accounting for only 0.1 %. Most of them are artificial diamonds.
. Typeii diamonds are divided into IIA and IIB type based on impurities.
(1). IIA type diamonds: nitrogen containing or nitrogen -containing. Ultraviolet light does not radiate phosphorus light. No electricity. (2). IIB diamonds: non -nitrogen contains or nitrogen -containing, but it contains boron (b). Phosphorus light after ultraviolet light. semiconductor.
In nature, the number of diamonds II is very small. But the large (up to hundreds of carats) diamonds are all II. The natural blue diamonds that can conduct electricity are IIB type.
In this shows that most of the diamonds seen in nature are IA type; blue diamonds produced in nature are IIB type. The weight, color, clarity, and cutting (CUT) are the four standards used internationally to identify diamond quality, referred to as 4C. Except for weight, the other three C are judged in accordance with the internationally recognized diamond grading system GIA. gia is the abbreviation of Institute of American. It was founded by Mr. Richard T. Liddicoat in 1953. It is the most large -scale and most recognized jewelry and diamond appraisal agency in the global jewelry industry. The GIA certificate issued by the GIA appraisal room is recognized as the most credible certificate in the world.
The clarity is divided into six levels, as shown below: fl (flawless), completely clean. There are no defects inside and outside the diamond. This level can allow extra small face in the pavilion, but minimal faceless faces are not visible from the table; it can be seen that natural native small crystal noodles or diarrhea planes do not exceed the width of the waist circumference, or the waist does not not make the waist do not not do not not make the waist do not not not make the waist do not not not make the waist do not not make the waist do not not not make the waist do not not not make the waist do not not make the waist do not not do not not make the waist do not not not make the waist do not not do not not make the waist. Round; there are extremely small inside, since it is colorless and does not affect perspective.
if (Flawless), the interior is clean. There are no flaws inside, and there are some flaws on the surface.
vvs1 (very very slight included), very, very small internal flaws. There are extremely small flaws, and only small flaws can be observed from the pavilion or on the surface. The difference between VVS2 and VVS1 is that VVS2 has very small installation points and small stubbles (basically there are no defects inside).
vs1 or VS2 (Very Slightly Included), very light flaws. You can see very small flaws, and you can see the size and location. The difference between VS1 and VS2 is that VS2 may have tiny cotton -shaped objects and stubbles.
SI1 and SI2 (Slightly Included), mild flaws. You can see defects under the mirror of ten times.
i1, i2, i3 (Inperfect), unclean level. You can clearly see the flaws, and sometimes you can clearly see clearly. rnrn－－－－－－－－－－－－－－－－－－－－－－ rnrn重量(Carat) rn钻石重量以Carat (Clarks) Calculation. "Clar", the seeds (rice beans), the seeds of corner bean trees (rice beans), the earliest unit of heavy units. The corner bean tree has a peculiar phenomenon. No matter where it grows, the kernels they condensed are consistent with each weight. In history, this fruit is used as a weight to measure weight, and over time, it has become a weight unit, which is used to call valuable and subtle substances. In 1907, the international business unit was used as a gemstone. 1 carat = 0.2 grams, because the diamond is precious and rare, it is bound to be further subdivided in measure, so it will be divided into 100 points into 100 points. For example, a diamond weighing 0.18 carats can be called 18 points. Essence rnrn－－－－－－－－－－－－－－－ rnrn钻石的颜色有很多种，一般我们会碰到无色、白色、淡黄色Three types, the depth of the tone directly affects the quality and value of diamonds. GIA divides the diamond color from D to Z to level 23. The whitening is D -Class, and the deepest yellow is Z. The appraisal of color grade mainly depends on more viewing, and requires experience accumulation. Generally, the color level of I level I is better. The higher the level I is higher, the brighter, and even the crystal clear, the higher the value. Below level I gradually began to feel slightly yellow or even yellow. Different levels will have a certain difference. Therefore, when you buy diamonds for the first time, it is recommended to buy diamonds containing GIA appraisal, which is more secure. rnrn－－－－－－－－－－－－－－－－－－－－ rnrn切工(Cut) rn切工，即钻石The method of cutting and polishing is the most important step in diamond processing. If the color and the clarity are formed naturally, then cutting is a masterpiece of people. Only after fine cutting can we have a precise face -to -face angle, can we reflect and reflect the maximum amount of light, and truly become a dazzling diamond. The appraisal cutting is mainly based on whether the diamond style can show its beauty, whether the angle and proportional relationship are correct, and whether it is fine. The main evaluation indicators of cutting classification are: countertop percentage, crown angle, bottom depth percentage percentage, waist thickness, sharp bottom size, modification (degree of polishing and symmetry). Generally speaking, the percentage of the countertop is 55%to 66%. Please see in detail: iask.sina/b/11994808
1. Blue and white diamond A kind of colorless transparent diamond like water, especially light blue. Such as "Centenary" and so on. 2. Red diamond The pink to bright red transparent diamonds, especially bright and red -red as rare treasures. Australia is its main source. (There is only the first level in the red color diamond grading, and there is no Fancy Intens, vivid, light red) 3. Blue diamond A kind of sky blue, blue to dark blue transparent diamonds, which are the best with dark blue. This diamond is different from all other colors of diamonds. It contains boron elements and has electrical performance. Because it is particularly rare, it is a rare treasure. Such as the world famous drill "The Hope", etc., the Polimir mine in South Africa is its main source. 4. Green diamond . A light green to green transparent diamond, mostly due to the deformation of the crystal structure, the color is usually only on the surface of the diamond. The green diamond is not easy to have a green color of the grassland. Among them The most uncomfortable. For example, The Dresden is the world's largest green diamond. 5. Purple diamond A transparent diamond with pale purple to purple is three times more expensive than colorless diamonds. Among them, purple -red people are rare treasures, and the former Soviet Union is its main source. 6. Color yellow diamond . A golden transparent diamond is a common variety in colored diamonds. It was estimated that there were $ 12 million at the time. 7. Orange diamond The orange is yellow and red mixture. Usually, the color tone is dark, and the pure orange color is rare in natural color diamonds. In October 1977, on the Sotheby's auction in New York, the 5.54ct Fancy Vivid Orange (Pumpkin Diamond) was sold at a high price of more than 1.3 million US dollars. 8. Black diamond black diamonds are usually not used as gem -level diamonds, but the world famous diamond "The Black Orloff" is rumored to be a diamond inlaid in the Holy Element in the Holy Element of India, also known as the Eye of Brahma
The types of diamonds can be divided by color. The color of diamonds include three major series: Cairpip series, brown series, and color series. The colorless to light yellow belongs to the Kaipu series; the brown series includes brown diamonds of different intensity; the color series includes pink, purple red, golden, blue, green and other diamonds. Most gem-grade diamonds belong to the colorless-light yellow series in the Kaipu series. This series of diamonds is also the most daily purchase of consumers. The whiter the color is, the more rare, precious, and higher the value. The color of the color of the color diamond, the higher the better the saturation. In the past, colorful diamonds were scarce and expensive. Since the found in Western Australia, many red and rose diamonds have been found in Western Australia, which has greatly enriched the world's color diamond market.
