Diamond reflects faint yellow and blue light when it rotates, but zircon is different. Because zircon has good refraction, it will reflect more colored light when it rotates. Secondly, no matter how high the quality of diamonds is, they are also flawed. Zircon is very clear and free of impurities. Generally speaking, the hardness of zircon is lower than that of diamond, so its cutting is incomplete. If you look under a magnifying glass, there will be some potholes in its cross section. -Quoted from Sugar Net

Diamond, a gem, need not be introduced too much. They are common jewels in daily life. Everyone will have a diamond ring as a token of love at the wedding, symbolizing the eternal love between two people. It is a silicate mineral zircon, which widely exists in acid igneous rocks and partly contains radioactive elements. The cut zircon looks like a diamond, and it is difficult to find tiny cracks with the naked eye. This is a masterpiece of nature. They are like the twins of Mother Earth.

Diamonds are highly lipophilic. Dropping grease on the surface of a diamond will leave the surface. Zircon is not lipophilic, so oil cannot stay on the surface. In addition, find an oily pen to draw traces on the diamond surface, and you can't see any handwriting on zircon.

Commonly used zircon is colorless, reddish brown and brownish red, and rare blue is the most precious. Diamonds are of better quality and higher prices in the market. Zircon can generally be sold after heat treatment. High temperature can make zircon colorful, showing various colors, and zircon will become more beautiful and sell better.
