wholesale brass jewelry stampings Diamonds are better than fluorescent than fluorescent.
The fluorescence of diamonds refers to the light emitted by the diamonds under the inspiration of ultraviolet light. It cannot be seen in normal light, but the diamonds with strong fluorescence in the sun will still have a hazy feeling. Although fluorescence has little effect on the diamond itself, it will still affect the price of the diamond itself.
The stronger the fluorescence, the greater the impact on the diamond. The transparency of the diamond itself will weaken, the color clarity is not pure, and there will even be some feeling of white mist. Most of the diamonds on the market generally have weak fluorescence, and the fluorescent diamonds are very rare.
If in my country's "Diamond Tie" standard, the fluorescent strength level of diamonds is divided into four levels: strong, medium, weak, and none of them. Generally, slight fluorescence or moderate fluorescence is not affected, so it can be included in the scope of consideration, but if it is choosing to collect it, it is better to choose as much as possible.
This information:
1. What is called diamond clarity?
The diamond clarity is also called diamond purity, because diamonds are natural minerals, and their characteristics are generally transparent, so it will contain some natural flaws such as other minerals or cracks. The more rare, the higher the value. Therefore, GIA (American Gem Research Institute) released the level standards of the size, quantity, color, location and other characteristics of the diamonds. One of the diamond 4C -diamond clarity.
2. How is the fluorescence of diamonds?
(1) The fluorescent response of the diamond is caused by external stimuli. Generally, it is mainly exposed to the reaction color light generated under ultraviolet line. Everyone knows that diamonds are a single element carbon composition. Under the ideal situation, the real situation is that when diamond formation is formed, there are often impurities added. The most common impurities are nitrogen atoms, because the radius and carbon of nitrogen atoms and carbon The radius of the atom is very similar, so nitrogen atoms will easily integrate into the crystal of the diamond, and at the same time occupy the lattice position, and then form impurities of substances. Fluorescence. Therefore, the emergence of fluorescence reactions is mainly a physical reaction formed by nitrogen atoms into diamonds. It can only be observed under special lights, which will not cause any damage to the human body.
(2) It is normal to have fluorescence in diamonds, but not every diamond will have fluorescent phenomena. Some diamonds are favorable. Strongness and weakness will also distinguish the level of fluorescence. Among them, the blue fluorescence can increase the bright whiteness of the diamond. The yellow fluorescence can effectively reduce Baidu. The blue fluorescent diamond level is whiter than the diamond level without fluorescence. This is caused by the size of the diamond and the strength of fluorescence.
