The emerald cuff links iron oxide

Meanwhile, the color produced from the chemical composition in terms of its appearance there, so this is another point of emerald cufflinks of UV-visible absorption spectrum. Causes the color emerald cufflinks of the original chromophore. Mainly caused by the transition metal ion color, emerald cufflinks structure by crystal field theory, research shows that: the color formed in the emerald cufflinks diagenetic stage (in particular the high-pressure low-temperature environment, rich in Na, Al's original rock by metamorphism crystallization and recrystallization to form jadeite rock) late. In the view of Mr. Huang, whether it is wearing a suit or Tang suit, you can always wear cufflinks on the exposed cuff.  Arising primarily from the following two functions, metamorphic differentiation: composition more uniform jadeite rocks in the metamorphic environment specific temperature, pressure and flow conditions.
 It contained trace amounts of and other color-causing ionic activation of migration, the local concentration enrichment, instead of Al3 ion from the color. But first is to choose the right shirt to go with the cufflinks.  Ductile deformation: jadeite rock at high pressure by the tectonic stress and ductile deformation, the jadeite rocks and ultramafic rock metasomatism produced between the double-rich and other ions in the fluid caused by the gradual invasion of color ductile deformation zone, which makes ductile deformation produced by the dynamically recrystallized grain size in the nucleation and growth occurred during the replacement account type role, the and other ions into the lattice made of jadeite color. Produced after crystallization in the emerald cufflinks, cufflinks jade is native surface oxidation and hydrolysis in the result, the common yellow and red and oil blue.
There are two mechanisms: First, iron oxide mechanical penetration mechanism. Infiltration along the fissures within the emerald cuff links iron oxide, yellow iron tend to form a dye, since the destruction of the original chromophore role; along the coarse particles into iron oxide mineral crystals, forming a fine limonite near the epidermis mainly Huang Wu, by hematite in the main house to Hongwu. French suit the best choice to pair with the formal cufflinks. Second, the secondary oxidation mechanism, with Fe in the weathering of high jadeite under the is oxidized, leaching precipitation, the emerald cufflinks in content increased, showing a dark green color on top of it is growing in the original, with the the precipitation of iron increased green thicken.
Increase transparency, that the formation of oil blue jade cufflinks. But the fundamental reason is that the survivors in the table immunogenicity water  rock reaction under the effect of filling mineral precipitation in the jadeite jade cufflinks micro-cracks (including cracks, gaps and jadeite cleavage, etc.) among the chlorite aphanitic times students due to clay minerals. color and chemical composition of jade cufflinks. After the election of the shirt, the next step is to single out the appropriate cufflinks. Mineral and chemical composition of jadeite theoretical  SiO2: 59. 45%; Al2O3: 25. 21%; Na2O: 15. 34% compared to. Mainly composed of emerald cufflinks jadeite-based, there are other minerals pyroxene and amphibole minerals, chemical composition has changed, emerald cufflinks chemical composition of Al2O3 is generally 18 to 24%, generally very difficult to achieve 25.21% of the minerals jadeite standards.
 Mainly due to Mg, Fe, Cr and other elements in the M1 position in the crystal structure of the replaced part of A1, making the reduction of Al2O3. D orbitals of these ions with the electron cloud around the oxygen ions play a role, resulting in energy splitting of different energy levels corresponding errand visible wavelengths of light energy is absorbed, electrons make transitions. Unlike rigid shirt buttons, cufflinks, whether in materials, technology, style, shape, color, even in grade and price, there are too many choices. Emerald cufflinks the final color of reflected light is not absorbed all of the integrated color. The closer the color is usually colorless and transparent, emerald cufflinks Al2O3 content in the mineral jadeite closer to the theoretical value, the more dense emerald green mens cufflinks, Al2O3 content of the more reduced.
