jewelry wholesale stores Diamond -the oldest and most precious natural treasures in history, with its sun and dazzling, win the hearts of most women. , A forever spread. "
but the choice of diamonds really causes a headache. Most people know that the size of the diamond is related to the price. The larger the diamond, the higher the price, and the quality of the same weight. The quality is left and right. The price of the price, the size of the diamond, can everyone see it, but the quality cannot? How to choose a diamond that is suitable for your own?
The diamond is beautiful and unique, each of which is related to its value. To understand the value of a diamond, you must start with 4C -color, clarity, cut (cut), and cact.
. Color: color
The quality and price of diamonds that directly affect the diamonds, most diamonds are white (white here is different from the general sense of white, which can be considered as colorless transparency) Essence The criteria of colors in the world are also relative to this series. At present, the color assessment of colorful diamonds has not yet formed standards, and it is difficult to encounter in the market. The standards introduced here are also for colorless -light yellow series diamonds.
. 1. Different diamond colors and different systems of diamonds are different, but they gradually agree with the hierarchical standards proposed by the American Jewelry Academy (GIA). The standards adopted by the country in my country are basically the same as GIA. The color grades of GIA and national standards are marked with English letters, from the highest color level D to the lowest color level Z, and the color is from white to yellow, with a total of 32 levels. Sexual, divide it into level 12, as shown below:
The letter represents the number indicating
nD 100 pole white r
f 98
g 97
h 96 white
i 95 slightly yellow (brown, gray) white
J
nk 93 light yellow (Brown, gray) white
L 92
m 91 light yellow (brown, gray) white
n 90
u003Cn u003C90 yellow (brown, gray)
It as can be seen from the figure above, the diamond grade of G -level is the best, the worse it goes down. In our country, the color can also be represented by numbers and text, so in some diamond identification certificates, there are also numbers or text to represent the clarity.
. The clarity: Clarity
The price of diamonds that also directly affects the diamonds. Each diamond is unique, and at the same time, it contains the inherent internal contents such as minerals or unscrupulization. Carbon is like a natural birthmark, and the quantity, size, shape, and color of these inside will determine the clarity and uniqueness of a diamond. Each trained expert can use a 10x large mirror to judge the clarity of diamonds, but in fact, most of the diamonds above the SI level cannot be distinguished by the naked eye. The less the diamond contains, the more light refraction, and the diamonds are doubled.
The clarity is divided into IF (also known as LC, flawless under the mirror), VVS1, VVS2, VS1, VS2, SI1, SI2, i eight levels, of which the IF level is the best, the price is the highest, and level I is the most. Difference.
. Cut
The nature determines the color, clarity and weight of a diamond, and a slight diamond with a car. It is distributed to the dazzling brilliantness and fire. When the diamond cutting ratio is appropriate, the light is like a mirror reflection. After the refraction of different surfaces, it emits the flowers of the light. Poor cutting diamonds will greatly affect the brightness and fire of diamonds, making the diamonds secretly losing color. Therefore, the value of the cut diamonds is high. When choosing, you should appreciate it carefully.
. Four, weight: cara
The calamine, 1 gram = 5 carat. 1 carat = 100 points. The larger the diamond, the rarer, and the price is also rising in a square. However, the value of the two same carat weights is also different from different color, clarity, and cutting.
Thising diamonds, the most important thing is to buy a diamond that is suitable for your own. Do not be greedy and cheap to buy some secondary goods, but it is not necessary to spend very expensive. In short, the right is the best.
