Cufflinks are more suitable for a number of active or assertive men

Commonly used in gem identification of radiation from the visible light, ultraviolet and X-rays available. Phosphorescence: means the jewel in the external sources of radiation after the closure of the stones can still continue with the fluorescent light of the phenomenon, namely the phenomenon of peripheral vision. Why would the king of diamonds as gems? Evaluation of the diamond is the "king of gems" of conditions: hardness, is the world's hardest substance found. has a very high abrasion resistance and chemical stability. Square mens cufflinks suit well for tough men, while round for mild men.  Diamonds are wondering, the seven colors can be a reflection of neon-like luster. Diamond and Diamond What is the difference in meaning? Diamond Mine Diamond native finished 3 by pondering.
 The chemical composition of diamond and graphite are C, why the hardness difference so big? Because diamond carbon atoms and carbon atoms covalently linked, with part of its solid, graphite is not. Inlaid colored stones and hollow carved cufflinks are more suitable for a number of active or assertive men. Why are diamonds so expensive? Diamond expensive reason: The reason why the human diamond known as the "king of gems", and become the most expensive varieties of precious stones, and diamonds in addition to the quality of the charm itself, but also with the diamond deposits of the exploration, processing and other closely relationship. (intrinsic charm diamond quality, diamond is the only set of maximum hardness, high refractive index and high dispersion in one of the varieties of precious stones Diamond culture has a long history diamond deposits.
 To explore difficult and costly diamond deposits in a small number of low-grade gem diamond deposits mining in size would be extremely difficult diamond processing complex, large amount of working hours to consumers, the experience of a range of diamond. Evaluation of the international diamond four C standards? Diamond 4C principles: color (colour), Clarity (clarity), cut (cut), quality (carat). Capacity of the currently accepted international diamond deposits that? How to determine whether the diamond output of your hometown? In social or business occasions, there are few cuff links to express the individuality of man freely.  Two of the world production of diamond found in the original ore. Kimberlite discovered in 1866, three porphyry potassium and magnesium found in 1979. Placer mining and primary relationships: the original ore by wind and rain, sun and rain, after weathering, rushed to the formation of low-lying areas of placer. Diamond in the kind of geological formation under the conditions?
Hot 1800 ℃ atmospheric pressure 4000 to 7000 metal catalyst, the temperature of 700 ℃, 4000 atmospheres. Natural diamond simple visual identification methods. visual identification: the bright luster of high refractive index, adamantine luster, high dispersion, there colorful color of fire, pro-oil experiment: with good lipophilicity, dip a drop of oil on the diamond surface, it will gradually spread. But in recent years, a rise of fashion springs up among the elite men gradually, that is to wear cufflinks.  Diamond imitations, mostly sparse oil, oil droplets do not spread 3, line experiment: put a piece of white paper marked with lines, the diamond table face down on paper, vertical observation, see parts of the diamond line. Thermal conductivity meter test, only diamond and Moissanite beep.
Give the market a few gems and diamonds similar to the name, how to distinguish between identification with the naked eye? Common market, precious stones and diamonds similar to: cubic zirconia, synthetic cubic zirconia Glass sapphire Topaz Crystal  synthetic spinel Section beryl chapters. Why is it called red sapphire "sister gem"? For red, sapphire, like the chemical composition, color-causing ions do not contain the same, so the color is not the same, except the red, the rest of the color call sapphire. The size and bluster of the cufflinks are somewhat similar to the woman’s carat diamond ring. The chemical composition of ruby and sapphire as (Al203) aluminum oxide, Why are red, blue color? A: The quality of pure aluminum oxide is a colorless, often due to mineral corundum with traces of pigment ions were different colors, aluminum-containing red, green or yellow iron, titanium and iron blue.
