Many friends often hear the word 'rhinestone' when buying jewelry, which probably means imitated diamonds. In fact, rhinestones are just a general term for imitation diamonds, and rhinestones have many distinctions. So what exactly is the so-called 'rhinestone'? What is the difference between it and real diamonds? The following jewelry manufacturers introduce the types of 'rhinestones' that you usually see on the market: 1. Glass: Fake diamonds made of glass are easy to distinguish, because it has a low refractive index and does not have the sparkle of real diamonds. Colored light, people with a little experience will know it at a glance. And this 'rhinestone' is often used in relatively cheap jewelry. 2. Artificial spinel: It lacks the colorful light of diamond, so if it is immersed in diiodomethane, its outline will be blurred. The outline of a real diamond is very clear. 3. Artificial sapphire: Colorless and transparent artificial sapphire can also be used as a substitute for diamond after polishing. But it almost disappears in the 'diiodomethane4. Crystal and Topaz: The transparent crystals of these two natural minerals are similar to diamonds after being polished, but they lack the brilliance of diamonds. And they are all 'heterogeneous bodies5. 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 gem 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. 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. Because cubic zirconia is very close to natural diamonds in terms of refractive index and dispersion. However, its hardness is low (8.5) and its specific gravity is 1.6-1.7 times that of diamonds, reaching 5.6-6, and its thermal conductivity is much lower than diamonds, so it can still be accurately distinguished from diamonds by instruments. Everyone finally understands the concept of 'rhinestoneUnder normal circumstances, under natural light, the brilliance of diamonds is unmatched by 'rhinestone' imitations (but there are exceptions, such as strontium titanate fake diamonds and moissanite, brilliance even surpasses real diamonds). It is recommended that you do not buy if you are really in doubt during your daily purchase or buy it under the guarantee of a certificate issued by a professional and authoritative testing agency.
