(3) The specific gravity of diamond is 3.52, while that of zircon is above 4.2. The tension of zircon is due to its low dispersibility. Colorless zircon is the best substitute for natural diamonds. If you want to have a diamond-like natural gem and are short of money, buying a zircon ring is the best choice. (3) The specific gravity of diamond is 3.52, while that of zircon is above 4.2.

If you want to have a diamond-like natural gem and are short of money, buying a zircon ring is the best choice. 1, identification and evaluation of zircon: Zircon is Zr [SiO _ 4], hardness is 7 Zuo Zuo, pore size is relatively low, dispersion is relatively low, single pore size is relatively low, and a single shadow can be seen. There are not many zircon imitations of other materials on the market. In many cases, zircon is used to imitate other precious stones, such as diamonds. The main difference between zircon and diamond is that if diamond can produce colorful "water" without light and single shadow. On the other hand, zircon has a strong "water" color and can be regarded as a single shadow. In addition to colorless zircon, there are two kinds of strong zircon, white and blue. Others, such as brown and green, are not nervous about gems. Zircon is the falling stone in February of 65438+, which means "victory". The suspected Shiluzhai Urban Forum is zircon. This is a gem. 2. Evaluation and selection of zircon jewelry How to care for zircon mainly depends on color, purity, cutting format and weight. The most declining colors of zircon are colorless and blue, and the price of blue is lower. Colorless zircon: It is the worst kind of gem-grade zircon. Because of its dispersion, it is transparent and colorless, and is often used as a substitute for diamonds. Blue zircon: It is the second-class zircon with the lowest cost. The blue color of Chen Su and its transparency make people happy and sad about the dispersion in air combat. Zircon is hard, and its hardness is much lower than that of diamond. Be careful when you wear it as an ornament. Distinguishing the brightness of the key surface, you can see that there is a single shadow inside. (1) Zircon is a kind of heterogeneous body, Liuzhou in Qin Dynasty. Looking down from the top of the carved zircon, we can see that there is a clear single shadow at the bottom edge, while diamonds do not have such a single shadow. 4. Although zircon is similar to diamond, it plays a great role in distinguishing zircon, which can be generally divided into white zircon and low zircon. Low-type zircon fruit is radioactive and not suitable for gold decoration; Only colorless and white zircon with low transparency can be used as gems, while elegant blue zircon can be altered by stopping the heat treatment of white zircon (recognized by the international jewelry industry). (2) The hardness of diamond is 10, while that of zircon is 8. Zircon is used to describe the standard hardness of 9, which can be distinguished from diamonds without moving for a moment. 3, zircon gold jewelry purchase skills (2) zircon is strong, Liuzhou mobile phone, the surface edge is easy to wear, pay attention to its edge when buying. The key to evaluation is impurity, transparency and good color. I teach jewelry. Ask me if I have any results. The main producing areas of zircon are Cambodia, Sri Lanka and Myanmar. In fact, it was not a simple matter to mine zircon in those days. Because zircon is mostly located 8- 10 feet below the topsoil, and the deposits on that day are mostly below the waterline, water is often swallowed out of the mine when mining. In Sri Lanka, when mining, people often hold some mysterious ceremonies to pray for God's blessing and let the mining go smoothly. It's about how to tell the true from the false when you put it in a straight line. You can see two lines from the edge of the sculpture. Liuzhou ASUS Notebook (the fruit with single emissivity of zircon) (1) If you want to choose a substitute for diamonds, you'd better choose black and round cut zircon. The most tense feature of zircon is that it has two shadows. In addition, zircon has a strong watercolor, and it can generally be seen that there is white in its rainbow color. In addition, it is worth noting that the "Soviet diamond", "round zircon" (nozzle), "Ukrainian zirconium" and "purple zirconium" that people often talk about in the market are actually not real zircon, and they have different identities from natural zircon. Among them, the Christian names of "Soviet diamond" and "round crystal zirconium" are sitting round zirconia, and the tension between them is different from zircon. The price of zircon mainly depends on several fruit factors, such as color, transparency, clarity, size and workmanship, and is greatly influenced by market fruit factors. There is a great demand for blue zircon in Chen Gu market, so its price is lower than that of zircon of other colors. The influence of other fruit elements is different from that of common gems such as garnet.
