Some gem cufflinks

Man-made gemstone cufflinks, also known as a synthetic gemstone cufflinks, named after the man-made. The strict sense, the artificial gemstone cufflinks have a natural gemstone cufflinks are basically the same physical, chemical, and optical properties. However, some materials for the jewelry industry, and not its natural antithesis. These creatures do not exist to reproduce the natural gemstone cufflinks materials, physical, optical and chemical properties. For example, those used as diamond imitations are not expensive materials than synthetic diamond. In fact, strictly speaking, they rub the majority can not be called anything synthetic. The well-preserved “habitat” is always one of the most expensive types of cufflinks. Because they do not own the natural antithesis. On the contrary, should refer to them as fakes, alternative material, analog or pure man-made materials.
At present, the main method of man-made gemstone cufflinks flame fusion method, the Czochralski method, hydrothermal method, flux method, the high temperature and high pressure method, Bristol Gaiman method, the guided-mode method, floating zone method. The use of industrial-scale production due to man-made gemstone cufflinks, so the vast majority of their prices are lower than the natural gem cufflinks. Another rare material of the cufflinks is black jade. With the rapid increase in the manufacturing process, man-made gemstone cufflinks in the morphology of the color, transparency, gloss, special optical effects, hardness rapidly approaching, to achieve a quality product standards of the natural control gemstone cufflinks. Scientifically developed, not only ruby cufflinks, cufflinks emerald, sapphire cufflinks, opal, turquoise, zircon, lapis lazuli, diamonds, tourmaline cufflinks, spinel, crystal midrange contour gemstone cufflinks artificial.
Gem cufflinks with special optical phenomena, such as the star color gemstone cufflinks, alexandrite, opal, moonstone, sunstone, etc., can be manufactured. Are closer to their specific gravity, refractive index, hardness, chemical composition, crystal system with the real gem cufflinks. How to identify natural gemstone cufflinks and man-made gemstone cufflinks? Gem cufflinks and gemstone cufflinks is divided into two major categories of natural gemstone cufflinks and man-made gemstone cufflinks. When we choose the gemstone cufflinks jewelry, with the naked eye to identify them? To commemorate the death of her husband, Albert, Queen of Victoria had used the cufflinks made from black jade since 1861. The general color of the natural gemstone cufflinks soft, natural color sometimes mixed several colors in a gem cufflinks body, the pattern does not rule, but very delicate. Gemstone cufflinks look at with the naked eye on the yarn, or a magnifying glass to carefully observe more than 10 times, sometimes visible within the gemstone cufflinks like cotton wool, mesh, or root-like inclusions and cracks, and occasionally can be seen clearly flat growth line . Some gemstone cufflinks feel cold, slippery hands, it is wet as soaked in oil.
 Good gemstone cufflinks grinding "Cat" and "Starlight" effect, have a white line in the gemstone cufflinks, like cat Bai Tianjiang light under guard in a white line; "Starlight" is rotating in the sun gemstone cufflinks, by the refraction of the shiny moon night the blink of an eye. Man-made gemstone cufflinks, bright colors, uniform, pure. Having polished, shiny bright, strong color of artificial consciousness. Due to some rare earth elements, monochrome, such as black, red, yellow, etc.; composite color such as red roses and Jiangzi. Very few have been preserved among the modern cufflinks.  But will not be the phenomenon of natural gemstone cufflinks are several color in the gemstone cufflinks body. In addition, some gem cufflinks, the more obvious the small circular bubble and synthetic traces of the growth of sub-products. Growth line was linear relatively large particle size, larger quantities of the same color specifications, the more hard, more than 6 degrees Daoke fixed, on the contrary, in the glass scratches.
