The best among diamond-color diamond

The mineral name of a diamond is Diamond. We often see a pen-like tool taken by a glass-cutting master. There is a dot on the tip of the pen, and the dot is Diamond. (The hardness of diamond is the largest in nature, and the hardness of Moshi is 10 ). However, not all diamond crystals can be referred to as diamond. diamond crystals that truly meet the requirements of the gemstone level can be called Diamond. This ratio is actually very small, only a few percent.

Diamond is rich in color and can be divided into two series: colorless series and color series. The colorless series includes colorless, white, ***, pale ***, gray, and Brown. The color series includes blue, purple, green, ***, pink, and black. The vast majority of white diamond and diamond with slight yellow or brown, collectively referred to as colorless (or near colorless) Diamond, and based on them with yellow (brown) the degree (or the degree of absence of yellow and brown) determines the Z level from the colorless D to the more multicolor. If the value of *** exceeds Z, it enters the fancy (color drill) range and becomes the color drill level. The Colorado diamond is rare in the world and is hard to find.

How to identify the authenticity of Diamond

Professional ** stores mainly use instruments for identification of genuine and genuine diamond. This ensures the quality and provides accurate data to buyers. General collectors are generally identified by the naked eye.

When the naked eye identifies a diamond, the first eye should observe its luster. Diamond has a particularly strong diamond luster and is very dazzling. In addition, the diamond has a high dispersion value, and the dispersion is obvious. It can be seen from the surface of the diamond.

The shape of a diamond is designed based on the principle of total reflection of light. So when the light enters the diamond from the table, it will only be reflected from the table, rather than from the pavilion. So when we lay the paper with lines or cross on the diamond table, we can't see the lines and the cross from the top. Only diamond in the natural world has this phenomenon.

In addition, because the diamond has the strongest thermal conductivity, it will rapidly form a water drop on the surface of the diamond with its mouth facing the diamond. Also, because of its strong adsorption of oil and fat, the hands touch, will absorb the oil on our hands. Or write a ball pen on the surface of a diamond. These are methods to identify diamond.

Let's talk about how to identify fake colored diamonds. First of all, we need to have a concept in our mind that color diamond is very scarce and extremely expensive. Even the yellow diamond with a relatively low inventory is much higher than the ordinary white diamond. The color-changing diamond that we have seen in the market is mainly the Blue Diamond with radiation-changing colors, and the Blue Diamond is mainly the color-centric effect caused by crystal lattice defects caused by radiation. The disadvantage of such a diamond is that the color is too deep and uniform, and the change is stiff and unstable. In addition, the diamond processed in this way is no longer conductive, while the natural diamond is conductive.
