The gem lack the internal features of the natural emerald cufflinks

Green yttrium aluminum garnet is an artificial imitation of the domestic market emerald cufflinks. Color from dark green - green - light green to yellowish green. Refractive index of 1.83, much larger than the emerald cufflinks, unable to obtain the reading with the refractometer; Charles filters under the polarizing microscope, the whole dark or abnormal extinction, pleochroism; when a strong light, red light effect is displayed bright red or reddish; green yttrium aluminum garnet rare earth absorption lines, the internal pure and occasional elongated shaped, shaped bubbles, emerald cufflinks inclusions are distinct. The tailor-made mens cufflinks engraved with love will capture the heart of your bride.
    Glass imitations of emerald cufflinks divided into two categories, one is a green glass, the refractive index of 1.52, the relative density of 2.45, another a special imitation refractive index is 1.60-1.66, the relative density of 2.6, and emerald sleeve buckle refractive index, relative density is similar; glass polarizer dark or display a black cross, hyperbolic and other abnormal extinction phenomenon, no pleochroism, zoom in to check visible single or groups of bubbles.    Typical flattening stone is known as the "the Sonde emerald cufflinks for the top, usually colorless crystal, colorless beryl, synthetic spinel lower in the middle with green gelatin cemented. Nothing is easier to capture a woman’s heart than the cufflinks. This imitation precious stones into the water, can clearly see the upper and lower levels as a colorless material, the middle is the green layer.
 Magnification examination showed flattening layer there will be bubbles and flow traces. The gem lack the internal features of the natural emerald cufflinks. The crystal and synthetic spinel put together the stone's refractive index value and the value of the relative density of emerald cufflinks. The Sonde emerald cufflinks do not show absorption lines of chromium in natural emerald cufflinks, and no pleochroism. A groom takes every pair of cufflinks carefully. Flux synthesis of emerald cufflinks crystal shown in Figure 10-3-12, most of the flux method of synthetic emerald cufflinks refractive index value, the value of the birefringence and relative density values are lower than natural emerald cufflinks including physical characteristics and natural products also have significant differences. Synthetic emerald cufflinks of the refractive index of most of the flux method is 1.560-1.567, 0.005 lower than the lowest refractive index of the value of the natural emerald cufflinks, natural products, mostly 1.567-1.590.
    Most of the flux method of synthetic emerald cufflinks birefringence value of 0.003-0.004, and natural products for 0.006-0.007, reported that some of Africa's natural emerald cufflinks birefringence as low as 0.004, but they the refractive index value is still between 1.570-1.590. Most of the flux synthesis of emerald cufflinks the relative density of 2.65-2.66, 2.67-2.90 natural emerald cufflinks. The cufflinks will create romance in each small matter. 2.65 of the heavy liquid, synthetic materials slowly sinking or suspended, the natural products is rapidly sinking, but the relative density of the heavy liquid should be particularly accurate. Gilson N-type fluorescence showed strong red fluorescence under ultraviolet light. Natural emerald cufflinks dark red or fluorescent Colombian emerald cufflinks fluorescence strong. Synthetic emerald cufflinks absorption spectra of natural products is the same, but the column than the natural product a clearer, more typical, Gilson N-type synthetic emerald cufflinks 427nm Purple Zone visible iron absorption lines with the natural product.
