    Diamond ring according to 4C standards.
    4c is the weight cact, color color, clarity clarity, cutting Cut. (Note: 1 carat = 0.2 grams).
    M of all indicators of diamonds, the most important thing is cutting. Because the exquisite diamonds are mainly reflected in the effects of light reflection, in order to reflect this effect, in the case of the same indicators Color and Clarity, the color head of the diamond is basically determined by the level of CUT.

    1, weight cact: This is not the higher, the bigger the better.

    2, color colour
    In the 23 levels of the letter D to the letters Z. Diamond color decreases from transparency to white, light yellow, yellow, dark yellow. Value is also from high to low to high. What you want to say here is that the value of the stones of the color of the level of the level is not lower than that of E and F. Therefore, the price of the color follows the image pricing of the anti -parabolic line.

    1) d, e, f, this is the best file, this level of diamonds are colorless and transparent.
    2) g, h, the second grade, the diamond becomes white.
    3) I, j, third grade, diamonds are light yellow.
    4) below J is not suitable for wedding ring because the color is more flower. Unless the color drill below U color is mainly used for decorative ring.

    3, clarity Clarity: refers to the purity of the diamond, the higher the more pure prices.
    1) If, the best level, the interior of the diamond is pure
    2) VVS1, VVS2, only very very small amount of impurities (very very slightely), which can also be regarded as a diamond with a good Clarity
    3) vs1, vs2 is very slightely, and the naked eye cannot see the impurities. In other words, there is no difference in ordinary observation conditions.
    4) Si1, si2, impurities can be seen under 10X magnifying glass, and people with sharp eyes may also see directly.
    5) I1, i2, i3, secondary product.

    4, cutting Cut
    4c the only factors that can be determined. From good to bad, the level is: Excellent, Very Good, Good, FIRM, Poor.
    The color and clarity should also be selected to cut. At least to the Very Good level, otherwise the glory of the stones cannot be reflected, and the stones below Very Good look more like glass.

    5, other standards
    gia international certification of the best proportional standard ("strict selection" refers to the ideal golden ratio of diamonds):

    1) Total depth depth Percent: 57.5%-63%, strict selection 60%-62.3%

    2) Table Size desktop ratio: 52%-62%, strict selection 54-58%

    3) Crown Angle Grand Ministry angle: 31.5-36.5 degrees, strict selection 34-35 degrees

    4) Crown Height Height ratio: 12.5%-17%, strict selection 15-15.5%
    n n n n n n n n n n n n n n n n n R n5) Pavilion angle bottom angle: 40.4-41.8 degrees, strict selection 40.5-41 degrees

    6) Pavling depth bottom depth ratio: 42.5-44.5%, strict selection 42.5-43.5% n n
    7) Star Facet LENGTH Astronomical Face-to-face length ratio: 45%-65%, strict selection of 50-55%

    8) LOWER GIRDLE FACET Limanity Policy: 70%-85% , Strictly select 75%

    9) Girdle Thickness waist thickness: Thin, Thin to Medium., Thin to Slightly Thick, Medium, Medium To Slightly Thick, Slightly Thick Klite, strictly select Thin TOMIUMIUMIUMIMICK, Medium, Medium to Slightly Thick these three types of

    10) Culet size bottom size: NONE-VERY SMALL, Small, strictly select None

    11) Lishh Polish: Very Good or Excellent. , Strictly select Excellent

    12) Symmetry symmetry: very good or excellet, strict selection excellet

    18K gold 50 -point diamond rings Price: 15888.00 Diamonds are evaluated from four aspects (4C): weight diamonds weigh with carats, one carat standard weight is 0.2 grams, each carat is 100 points, a 25 -point one is 25 points. Diamonds can also be called 0.25 carats. Diamonds are priced at carat unit price × weight = price. The unit price of carats will change with weight, such as: 1 carat unit price = 50,000 yuan total price = 50,000 yuan × 1.00ct = about 50,000 yuan 2 carat unit price = 100,000 yuan total price = 100,000 yuan × 2.00ct = The value of about 200,000 yuan (non -50,000 yuan × 2.00ct = about 100,000 yuan) Diamond value is directly proportional to its weight. The more diamonds at the same level, the higher the weight score, the higher its value. The price on the score line is more different than the price on the general score line. The price between drilling and 99 -point drill is large. According to your economic strength, the larger the diamonds, the greater the potential of the value of the diamond, the greater the potential, especially the diamonds of more than 50 points. The weight of diamonds is often represented by carats. 3 -bit valid values ​​commonly used in commerce, such as "0275" represents 0.275 carats, unsolved diamonds can be directly measured with electronic balance. For reference, this is one of the important reasons why the reputable merchants buy, because it does not rule out the phenomenon of "lacking and less score" diamonds. The higher the clarity and color clarity, the higher the price, the white the color, and the higher the price. According to national standards, according to China's national conditions, the quality level table inlaid diamond (0.10CT ~ 1.00ct) was formulated, as follows: LC flawless VVS extremely flaw vs micro flaw flaskin p. The quality of work cutting has a great impact on the price of diamonds. The difference between a good cut and a difference is about 30%, or even more. Essence So cutting is not important. Then according to the "Diamond Cutting Table" below, you can choose the appropriate diamonds of the pavilion. At the same time, the more regular the shadow part is to be observed. The diamonds with a black bottom effect or a fish -eye effect are diamonds with poor cutting. Sometimes they can be observed without amplifying mirrors. Diamond cutting ratio and angle grading table (%) Generally good, good, general platform width ratio ≤ 50 51 ～ 52 53 ～ 70 ≥71 crown high ratio ≤ 8.5 11 ～ 16 16.5 ～ 18 ≥18.5 waist thickness thickness 0 ～ 0.5 1 ～ 1.5 2 ～ 4.5 5 ～ 7.5 ≥8 pavilion depth ratio ≤ 39.5 41.5 ～ 45 ～ 45.5 ～ 46.5 ≥ 47 bottom ratio ratio 2 2 ＞ 4 ≤ 52.0 ～ 55.5 56 ～ 63.5 64.0 ～ 66.5 ≥67.0 crown ≤ 26.9? B 27.0? B ～ B 30.7? B ～ 37.7? B 37.8? B ～ 40.6? B ≥40.7? Diamonds are natural crystalline minerals. There are many shapes of crystals. In addition, it will be damaged by geological effects during the formation process. Therefore, the diamond rough shapes of the mining are different, and the diamonds are expensive. Therefore, cutting is often processed according to its shape. To make full use of, there are a variety of diamonds processed in this way, usually divided into two categories: round diamonds and alien diamonds. The most common diamonds on the market are standard -shaped diamond cutting, with 57 sides.

    Buying diamond ring must first draw up budgets based on your own economic situation. According to the budget, suitable diamonds and rings can be used. Choose diamonds to see 4C. The larger the diamond volume, the more precious the diamond is. In the same volume, the higher the level of other 3Cs (cutting, clarity, and color), the more expensive the price.
