Emerald cufflinks the appearance of precious stones

Typical inclusions are fragments of biotite, hematite crystals (10-3-10). Mainly produced in Yunnan the hemp force slope, color light green or microstrip yellow, green, fissures, often containing within the gas-liquid two-phase inclusions, tubular inclusions and ribbons. The relative density of 2.71, the refractive index of 1.588-1.582, birefringence 0.006, under ultraviolet light inert filter reddish or no response. Straight and angular outline of the cufflinks set off the insistence of the men.  Yunnan emerald cufflinks color caused by vanadium, chromium trace. Other emerald cufflinks origin Austria Habach Valley, the upper reaches of the world, Norway Akerlls Province, Pakistan's Swat province, Australia, New South thorium, North Carolina, United States, Egypt and Madagascar.
Emerald cufflinks with imitation gem identification; Emerald cufflinks the appearance of precious stones, but according to the physical nature of precious stones, especially some of the key tests that can rapidly distinguish these imitations, its main distinguishing features are as follows: Blue-green fluorite colors like emerald cufflinks. The sight gloss of the cufflinkscan better highlight the gorgeousness of the groom. However, fluorite is a low refractive index (1.434), relative density than the emerald cufflinks, orthogonal polarizing microscope dark or abnormal birefringence, it is easy to distinguish. With the naked eye the luster of the gem is weak, the surface edge is easy to wear, and may show strong fluorescence under UV short wave, or even visible phosphorescence.
        Chrysoprase is a great difference in appearance of transparent emerald cufflinks, chromium salts artificially colored chalcedony is sometimes confused with cloudy emerald cufflinks. Dye significant light red, green chalcedony Charles filters with absorption spectrum in the red zone can be ambiguous. Low refractive index value, the polarizing microscope, all light, floating or suspended in 2.65 Heavy Liquid, emerald cufflinks will sink. This section of cufflinks is suitable for the silver dress with mercerizing fabrics. Dim blue-green to dark green tourmaline color and its refractive index of 1.62-1.65, bi-fold rate of 0.018, significantly after the engraved surface edge ghosting; the relative density of 3.01-3.11 higher than the emerald cufflinks, pleochroism, very easy to identify out.
Some heat-treated tourmaline color is very close to the emerald cufflinks, and do not show strong pleochroism. Tourmaline containing chromium may show some of the lines in the red zone and need attention. Emerald cufflinks, apatite also belongs to the hexagonal system, the six-party columnar crystal, refractive index, relative density higher than the emerald cufflinks, hardness, the birefringence is small, visible to a significant absorption line at 580nm at , and the emerald cufflinks. When the groom held the wine glass to the air, the pink diamond cufflinks along with goblet will glisten and twinkle.
      Dark green to yellow-green color, its refractive index of 1.675-1.70, the birefringence of 0.024-0.030 and the relative density of 3.29 was significantly higher than the emerald cufflinks; red zone visible chromium absorption lines, Charles filters red and emerald sleeve deduction similar. The color was yellow-green to bright green, the naked eye, chromium vanadium grossular Dan Guangze and the more brighter than the emerald cufflinks, its refractive index value of 1.74 and the relative density of 3.61 was significantly higher than the emerald cufflinks; in orthogonal partial light microscope dark or abnormal birefringence, no pleochroism emerald cufflinks. The red area shows the chromium absorption spectrum was red or pink and emerald cufflinks Charles filters. The cufflinks build the visual highlights at ease.
