Diamonds are luxurious noble ornaments, inlaid diamonds jewelry is the highest jewelry, everyone loved. However, because of the rare and expensive diamonds, especially large diamonds, most people simply unable to pay attention. Whether it can find some looks like diamonds cheap gems, used to replace diamonds to meet more people’s hobbies? These stones are all kinds of diamonds. There are two reasons for making fake diamonds: one is to avoid loss or other security reasons, there are Fake Cartier jewelry precious jewelry, usually also wear fake diamond jewelry, which makes fake diamonds sell more and more widely; Diamonds posing as genuine, high-priced sale of deceptive, which requires a quick and accurate way to distinguish between true and false diamonds. Glass Glass can not only be used to make fake diamonds, but also can be used almost as a substitute for any natural gemstones. Fake diamonds made of glass are easy to distinguish because of its low refractive index, no true diamonds, the kind of flashing color light, slightly experienced people at a glance. A very simple difference is that with a bowl of white bowl of water, will be suspected of diamonds into the water dipped in diamonds, colorless glass products as if disappearing in the water, can not see the outline of the true diamonds Diablo , In the water is very clear. Artificial spinel Like glass, the purpose of production is to serve as a substitute for many kinds of natural gems and impersonation. It is the difference between diamonds, the lack of flashing color light, it dipped in diiodomethane, the contour will be blurred, while the real diamonds are very clear. Crystal and topaz These are two natural minerals. Colorless and transparent crystal and topaz in the pondering, the rough look is also a bit like a diamond, look similar to the glass, the lack of flashing color light. In addition, they are “heterogeneous”, while the diamond is “homogeneous”, with a polarimeter can quickly distinguish. Artificial sapphires Artificial sapphires are mass-produced substances. It is not only as a substitute for gemstones, but also has many uses in industry. Colorless and transparent artificial sapphire in the pondering can also be used as a substitute for diamonds. Often such a situation, a set of small diamond brooch or necklace and other Cartier nail bracelet replica jewelry, may be part of the real, but mixed with some artificial sapphires made of fake diamonds. As the stones embedded in the jewelry, the test inconvenience, this time can be the whole jewelry dipped in “diiodomethane” This liquid. True diamonds in the liquid edge of the dark, as if in the liquid concave, very clear; artificial sapphire in the “diiodomethane” almost disappeared invisible, so true and false will be clear at a glance. In the absence of “diiodomethane”, the water can also be used, although the difference between true and false is small, but still very clear. In addition, the artificial sapphire is “heterogeneous”, while the diamond is “homogeneous”, the two with “polarimeter” is also very easy to distinguish. Zircon Zircon is a natural mineral, it is also a medium in the block. Colorless and transparent zircon after careful pondering, is a good substitute for diamonds. The refractive index of zircon is close to 2, the dispersion is also close to diamond. Therefore, from the exterior point of view, the color of zircon will be flashing light, and diamond is very similar. Diamond has a strong birefringence, that is, it has two refractive index, and the difference between the two refractive index larger. Thus there is a very special optical phenomena, when using a magnifying glass to observe the refined zircon products, the top surface can be seen from the bottom of the surface and ridge obvious double. Diamond because it is “homogeneous body”, there will be no double shadow phenomenon, which can distinguish between zircon and real diamonds. In addition, the proportion of zircon is 4.69, while the proportion of diamonds is only 3.52, that is 1.33 times the diamond zircon. However, the proportion of inconvenience observed, only after the instrument can be determined. Scheelite This is a common mineral in nature, the composition of calcium tungstate (CaWO4). It is characterized by a low hardness, only Mohs hardness 5, can be ordinary glass and steel knife scratches. Its proportion is very big, amounts to 6.1, is the diamond 1.74 times, the hand weighs quite heavy. Colorless and transparent scheelite can be used as a gemstones raw materials, it will be pondering, the beautiful color flash almost comparable with diamonds. However, the scheelite as hardness is too low, pondering a good gem if often worn, easy to scratch the sand and lose beautiful luster. Therefore, it is usually cheap Cartier bracelet replica only a collection of precious stones collectors appreciate a product, not as a mosaic of jewelry purposes. Artificial rutile Rutile is a very common natural mineral, its composition is TiO2, hardness 6-6.5, the proportion of 4.2-4.4, the refractive index higher than the diamond, up to 2.60-2.90. Rutile because of the high refractive index, so pondering into a gem will appear bright dazzling flash, dispersion and very strong, so flash the same rainbow color changes, it is very beautiful. Unfortunately, almost all natural rutile opaque, at least some of the edge of the crystal light, so rare rutile natural stones, and the particles are small. Rutile has been used as a gem of fine nature, so people have been studying the scientific synthesis of its methods. In 1947, the United States lead the company first with flame fusion system out of the artificial rutile. One of the colorless and transparent, is mainly used as a substitute for diamonds or counterfeit goods. Colorless transparent artificial rutile pondering the gem shining bright, colorful, more than a true diamond, often referred to as “colorful drill” or “colorless drill.” Artificial rutile finished products, the so-called “colorful drill”, and true diamonds is not difficult to distinguish. As the rutile has a strong birefringence, with a magnifying glass from the top observation “colorful drill”, you can find the bottom of the ridge of the significant double shadow, true diamond will never appear double shadow. In addition, the “colorful drill” because the flash is too bright, and with a clear milky white, it seems a sense of vulgarity.
