Teach you how to identify common fake diamonds! Diamonds are noble and luxurious ornaments, and jewelry with natural diamonds is the crown of jewelry. However, diamonds are scarce and expensive, especially the slightly larger diamonds, and people at the average consumption level have no guts. As a result, cheap gems, artificial gems and even glass are used to replace or impersonate diamonds, and the business of fake diamonds is also growing. How can we correctly understand the diamond ring? How to distinguish these kinds of diamonds teach you how to identify common fake diamonds! Diamonds are noble and luxurious ornaments, and jewelry with natural diamonds is the crown of jewelry. However, diamonds are scarce and expensive, especially the slightly larger diamonds, and people at the average consumption level have no guts. As a result, cheap gems, artificial gems and even glass are used to replace or impersonate diamonds, and the business of fake diamonds is also growing. How can we correctly understand the diamond ring? How can we distinguish these types of diamond rings? 1. Glass: Fake diamonds made of glass are easy to distinguish because of their low refractive index and no flashing colored light like real diamonds. People with a little experience will know at a glance. In addition, a white porcelain bowl can be used to hold a bowl of clear water. The colorless glass products that pretend to be diamonds can not be seen clearly when they are poured into the water, while the dark contours of real diamonds appear very clear in the water. 2. Artificial spinel: The difference between it and diamond is that it lacks the flickering color light. If it is immersed in diiodomethane, the outline will be blurred, while the outline of real diamond is very clear. 3. Crystal and Topaz: These two kinds of transparent crystals of natural minerals, after polishing, look a bit like diamonds, but they lack the sparkling color light. And they are all 'heterogeneous bodies 4. Artificial sapphire: Colorless and transparent artificial sapphire can also be used as a substitute for diamond after polishing. But it almost disappeared in the 'diiodomethane 5. Zircon: Before the emergence of man-made cubic zirconia, zircon was the best diamond substitute. zircon has strong birefringence, that is, it has two refractive indexes, and the difference between the two refractive indexes is large. This produces a very special optical phenomenon. When observing a polished zircon prismatic gemstone with a magnifying glass, it can be seen from the top surface that the bottom surface and the ridgeline have obvious double shadows. And because diamond is a 'homogeneous body6. Artificial rutile: Rutile is an ordinary natural mineral. Its composition is titanium dioxide. Because its refractive index (2.61—2.90) is higher than that of diamond (2.42), it can appear bright and dazzling sparkle after polishing the gem. And there can be rainbow-like changes, it looks very beautiful. It is a pity that almost all natural rutile is opaque, so it was only in 1947 that the American Lead Company produced artificial rutile. Among them, the colorless and transparent ones are used as diamond substitutes or counterfeit products, and their colorful sparkle surpasses real diamonds, and are often called 'fancy diamonds' or 'five-color diamonds.' However, because rutile has a strong refractive index, like zircon, the obvious double shadow of the bottom ridge line can be seen from the top surface with a magnifying glass, so it is easy to distinguish from diamond. 7. Cubic zirconia: (ie, 'Soviet diamond'): This is the most ideal diamond substitute or counterfeit product first introduced by the former Soviet Union. It is a man-made compound without natural minerals. Since the advent of cubic zirconia, many other artificial gemstones have been used only as substitutes for other low- and medium-grade gemstones, instead of grinding fake diamonds. This is because cubic zirconia is very close to natural diamonds in terms of refractive index and dispersion. However, its hardness is low (8.5), its specific gravity is 1.6-1.7 times that of diamond, reaching 5.6-6, and its thermal conductivity is much lower than diamond, so it can still be accurately distinguished from diamond by instruments.
