faux pearl bridal jewelry wholesale Good diamond! A forever spread! Eternal! Intersection Intersection The so -called "diamond" refers to gem -class diamonds.
Itdracka is in the depths of the underground. Under the conditions of high temperature and high pressure, it is formed by the carbon crystallization of the ground, and then comes with the magma to the volcanic pipeline. After the magma condensate, it forms a golden Permon Mother Rock with diamonds, and the golden Permon Mother Rock is brought to the surface with the volcanic movement. Because of the weathering effect, the golden Permon mother rock is broken.
Tracka is taken away from the original land with the water flow, forming diamond sand mines. Later, it was artificially collected by artificial collection and selection.
In all gems, the ingredients of diamonds are the simplest. It is just ordinary carbon chemicals, just like graphite in a pencil, but it becomes the hardest material in the world through natural power. In the vacuum, its melting point is the four stems of Celsius, which is twice the melting point of the steel.

Is to pay attention to "Four C" when selecting diamonds: CUT — cutting, Clarity — clarity, color — color and carat — carat.
cut -cutting: The cutting of diamonds is extremely important, which directly affects the value of diamonds. Only the standard cutting method can show its bright light and achieve the perfect combination of clarity and color. The cut diamonds are generally spheres or cone. There are many shapes in the cut surface, square, rectangular, hexagonal, circular and oval, etc., but the most popular is the simple hexagonal shape, and many of its cut surfaces can better show the light of diamonds.
clarity — Cleence: Diamond crystals in the mantle magma deep in the deep earth. After hundreds of millions of geological changes, it has various natural marks. The color, size, and position distribution of these imprints have different degrees of effect on the value of diamonds. Diamond surfaces or inside often have flaws, such as bubbles, cracks, and feathers. The less defects, the higher the level of diamonds. In general, the clarity of diamonds is divided into five levels and ten small levels in turn.
color —— color: the color of the diamond, from precious colorless, rare light blue, pink to common yellow. The more transparent the diamond is, the more white the white light can penetrate, and it is even more colorful after refraction and color. The whitening diamonds are D -grade, and the others are E, F, G, H, I, J, K, L, M, and N and N.
carat — Crants: The weight of the diamond is carved. 1 carat is equal to 0.2 grams. One carat is divided into one hundred points, such as 0.75 cents carat also known as 75 points. Diamonds with the same weight will be far from the difference in color, clarity, and cutting. For example, if a large 2 carat diamond is cut, the shape is too outdated, and the air bubbles are too much. And a diamond with only 1/2 caramel, if it is colorless, high in clarity, and the most popular cut, it will be more like and the price is expensive.

Mest diamonds are white, which can be divided into "colorless transparency" to "close to colorless" 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. Diamonds 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.

The color grading of colorless to yellow diamond

The colorlessness in the color grading of the diamond is the most ideal. D.E.F. The three levels are colorless, G.H.I.J's four levels are close to the colorless range, K.L.M is slightly yellow, and N is light yellow.

The summary, the closer the diamond is in colorless to the yellow series, the higher the value of the diamond, and the higher the value; the more yellow the diamond, the lower the value. However, below Z is called colorful diamonds, the stronger the yellow color tone, the higher the value.

The conclusion of the current national identification certificate is issued according to D-E, F-G, H, I-J, K-L, etc.

The suggestion for color:
(1) The significance of the color of the diamond is proportional to the size of the diamond. The larger the diamonds of the same color level, the more obvious the color of the diamond. When you buy diamonds below 0.3 carats, you can choose a slightly lower level, if it is not less than K color. It is difficult to detect the color differences of diamonds below 0.3 carats.
(2) The significance of the color of the diamond has a lot to do with the metal used in the jewelry. When using platinum as a base beto, it can better set off the beauty of the diamonds. However, because of the inlaid, only the color of the K level or above is enough.
The clarity refers to the normal vision, and the trained diamond grading personnel under the artificial standard light sources of D55 or D65, with ten times the color difference and equivalent of the diamond clarity characteristics observed from the light, from scratch to existence from scratch to The relative degree.

In 10 times large mirror to observe the number of diamonds and surface flaws, distribution, size, and the effects of diamond glory, can be divided into LC, VVS, VS, SI, P, a total of 5 large -level and 10 large and 10 10 large -level and 10 10 large -level and 10 10 large -level and 10 10 large -level and 10 10 large levels and 10 10 large levels and 10 Small level.

usually thinks that diamonds are crystal clear. In fact, most diamonds contain tiny internal contents. They are the result of mutation in the surrounding environment and other crystal invasion during the development of diamonds.

Although most of the diamonds contain the internal content, these internal contents do not affect the beauty of the diamond itself. Of course, the smaller and smaller the inner content, the lower the impact of the light through the diamond, and the more beautiful the diamond shines.

The national standard diamond clarity:
LC (flawless level)
Inned hierarchical personnel under the standard light source to observe with 10 times large mirror. Essence That is to say, the diamond does not contain any flaws that are greater than 5 microns and have sufficient brightness.
vvs1-vvs2 (extremely micro-flaw)
The experienced hierarchical personnel can find very small flaws with 10 times large mirror. It is difficult to be difficult. Determine whether it is VVS1 or VVS2 according to the size, location and quantity of the characteristics of defects.
VS1-VS2 (micro-flaw)
The experienced grades can find small flaws with 10 times large mirror. It is difficult to be difficult. Determine whether it is VS1 or VS2 according to the size, location and quantity of the characteristics of defects.
SI1-SI2 (small flaws)
The experienced hierarchical personnel can easily discover small flaws with 10 times large mirror. Determine whether it is SI1 or SI2 according to the size, location, and quantity of the characteristics of defects.
p1 (Xiaohua): Experienced grades are difficult to find the characteristics of defects from the crown of the diamond to observe the characteristics of the naked eye.
P2 (medium flower): Experienced hierarchical personnel are easy to find large and many flaws with the naked eye, which slightly affects the "fire" of diamonds.
P3 (big flower): Experienced grades are easy to find large and many flaws with the naked eye, which will greatly affect the "fire" of diamonds.

The suggestion to diamond clarity:
(1) The better the clarity of the diamond, the higher the price. When you want to buy a high clarity diamond or invest and collect it, VS level or above is the most suitable. When you have no special requirements for the clarity of diamonds, the choice of SI -level cost performance is the highest, and the naked eye cannot distinguish the SI and VS levels. Moreover, defects are part of the diamond, which is a unique label made by nature for each diamond.
(2) Buying a diamond ornament does not necessarily require VS and I levels. Diamonds embedded on the platinum support, the color reaches K color. For diamond ornaments below 0.25CT, especially bracelets, earrings, pendants, etc., do not have to be demanding for colors and clarity. As long as you work well, you can "fire" (referring to the big color of diamonds).
