The fire of diamond color how much you know

As one of the precious stones, diamonds have a strong knowledge of the diamond, if you are not professionals, many believe that most people have not enough knowledge, this article declare the fire color of diamond, diamond fire color actually is one of the diamond identification is an important link, can let more too. 1, internal fire color ( 内部才华) Inside the fire caused by by diamond refracted light. If the incident to the inside of the diamond light by diamond booth when the surface reflection, and its reflection from the crown ( Figure 8 - 1) , the sparkling diamond appears, bright bright brightness. If light all or part of the incident to the diamond from diamond pavilion, a diamond will appear inflexible, not beautiful. In order to fully display the internal color of fire, diamond must be carefully designed, how many, the original Angle between surface and surface must be subordinate to the optical properties of diamond, these are cut diamond grinding must consider the key. 2, external fire color ( 外部辉煌) Or luster, is caused by reflected light from stone surface, factors influencing the gloss strength of reflectivity, the higher the reflectivity, luster. But the reflectance and refractive index were positively correlated relationship ( The following type) : that is, arguably, strong luster of diamonds, its reason lies in the high refractive index. R0=( n - 1) 2 / ( n 1) 2 × 100%. R0 of reflectivity, n for refractive index. But in addition to the refractive index, the luster of diamonds still depends on the surface quality, smoothness and polishing, diamond surface is smooth, polished degree is higher, the more luster. In order to improve the fire of diamond color, must implement good cut for small diamond surface grinding and polishing. 3, the dispersion of fire color ( 色散辉煌) We know that the natural light of different wavelengths of monochromatic light, the light red ( 780 - 640海里) , orange light ( 640 - 595nm) , yellow ( 595 - 570海里) , green, 570 - 500海里) , blu-ray ( 500 - 400nm) And purple light ( 400 - 380海里) 。 When the natural light for certain optical reason is separated, will form a lace-up color chromatography, namely natural light chromatography. Due to the natural light in various monochromatic light refractive index difference exists in the diamond, so the incident to the natural separation will occur in the diamond. Through carefully designed diamond cut, separation of multiple reflections of light can be further separated from crown again after injection, so that we can see from the diamond crown diamond of monochromatic light, that is out of the fire. Diamond and process, the better, natural light is separated, the greater the fire color is fuller, diamond, the more the United States, the higher the value. 4, flash fire color ( scintillation brilliance) Flash is gem is rotating or light source was changed, the color of the stone, light and flash is the phenomenon of change ( 佩奇Verena - Theisen, 1993) 。 Into diamond depends on the actual amount of light reflected on the surface of the stone quantity, small size, geometric symmetry and surface polishing quality. In order to make the diamond when rotating or light source was changed, can produce the change of color, light and flash, so that the diamond rich life, must be based on the optical characteristics of the diamond, elaborate design and processing. It is hard to understand? These light see articles or not, to personally experience, the experience of jewelry shop, is a good place, you need diamond secret more diamond related knowledge in jewellery, if you have any advice to the website customer service related knowledge.
