4 thoughts on “What kinds of simulated diamond rings can replace real ones”

Imitation diamonds can't replace real ones. Here are some common varieties of imitation diamonds first, synthetic cubic zirconia is also known as "CZ Diamond", because it was first synthesized by the former Soviet Union and successfully introduced to the market as a counterfeit diamond in the 1970s. It is also known as "Soviet diamond" (this name has been abolished)
the properties of synthetic cubic zirconia are very similar to those of diamond. First of all, its refractive index is as high as 2.17, and its dispersion is 0.06, which is very close to the 2.42 and 0.044 of diamonds. In particular, its high dispersion makes the color flash of the polished gems more brilliant. The Mohs hardness of synthetic cubic zirconia is 8.5, which is only slightly lower than that of ruby and sapphire. It can make the cut edges sharp and perfect, and the smooth surface of the flash is not easy to be scratched and abraded. Moreover, the synthesis of cubic zirconia can produce products with excellent transparency and completely colorless. In this way, after it is cut into a round diamond shaped prism stone, its appearance is exactly the same as that of a diamond, and it is almost indistinguishable. In addition to the colorless and transparent zirconia, a small amount of chromogenic elements are added to the synthesized cubic zirconia to obtain bright red, yellow, green, blue, purple and purplish red products
although the appearance of synthetic cubic zirconia is very similar to diamond when it is ground into gemstone, it can be distinguished by some simple methods. The specific gravity of synthetic cubic zirconia is about 6, which is 1.7 times that of diamond (3.5), so it has a heavy feel; Or oil strokes can be applied to the surface of the sample to leave clear and continuous lines when they are applied to the diamond surface, and discontinuous small droplets appear when they are applied to the synthetic cubic zirconia; Or breathe into the sample. For the sample where the fog spreads quickly, it is diamond, and for the sample where the fog spreads slowly, it is synthetic cubic zirconia. Of course, it is best to identify them accurately through instruments, such as reflectometer, thermal conductivity meter, microscope, etc
as for the synthetic real diamond, because its synthetic cost is higher than that of natural diamond, and the synthetic diamond is often small and cannot reach the level of gemstone, so people need not worry about buying synthetic diamond in the jewelry market at least for now
II. Morsonite, a synthetic gemstone grade carbon silica, commemorates Henry, the Nobel Prize winner who first synthesized it in the 1990s Named after Dr. moysan. Recently, a North American company (C3 company) put it on the market as a diamond substitute crystal, which is considered to be a more realistic diamond substitute crystal than cubic zirconia. Because of the high thermal conductivity of morsonite, the thermal conductivity meter cannot distinguish. The main difference between it and diamond is that it belongs to the hexagonal crystal system and has heterogeneity. When viewed from the table top, the edges of the pavilion have double shadows and the relative density is low (3.20-3.22). Uniaxial normal crystal, N. = 2.69, no = 2.65, heavy refractive index 0.04, dispersion higher than diamond, 0.104. Mohs hardness 9.25. There are metal spherical inclusions and linear bodies composed of small white dots (approximately parallel to the c-axis), no fluorescent reaction and conductive. At present, it is impossible to be truly colorless, and there are often some grayish green or grayish blue, so its color can also be used as a distinguishing feature in the near future Third, glass, glass is more powerful. It can imitate many gems, not only diamonds... However, because the fire color is not strong, it is easy to find the difference between the real diamond and the fire color. Therefore, this kind of product generally does not appear in the market. In some schools, diamonds are cut with glass for training the most likely ones in the market are imitation diamonds of morsonite and synthetic cubic zirconia. However, if you are engaged in imitation diamonds of synthetic cubic zirconia, a conscientious brand will generally tell customers that his diamonds are imitation diamonds. Don't worry too much....
Zircon or high carbon drill is the worst simulation drill, so the price is very cheap. At present, the best synthetic gemstone that can replace the real diamond in the market is mosang stone. Mosang stone is commonly known as silicon carbide. Its physical characteristics are very similar to diamonds. In particular, fire color is 2.5 times that of real diamonds. It has been popular in Europe and America for many years and is deeply liked by young consumers.
Most of the simulated diamonds are zircon, with very low hardness, only 5-6 Mohs hardness, which is easy to scratch and cause scratches, and the fire color is inferior.

Mosan diamond should be the best substitute
