1, crystal quality is different, the United States has been researching and cultivating mosan stone for 20+ years, and its experience and technology are very mature. In this respect, it is absolutely impossible for China to catch up in two or three years. (Ps: Of course, it doesn't mean that domestic products are not good. In the past two years, the quality of domestic products has been getting better and better, but there is still a certain gap to achieve high quality, but there is still a lot of room for improvement. )

2. The experience and technology of cutting and grinding masters are different. Moss stones in the United States are all sent to diamond factories in India for cutting and polishing, while those in China are sent to zircon factories for cutting and polishing. Different standards, different technical experience, the quality of grinding three stones is also different.

3. The wearing durability is different. The domestic Mosangshi will appear black and discolored after wearing for a period of time, while the imported Mosangjing is relatively good, and this will not happen, so it is suitable for long-term wear.

4. It is precisely because of the above three main differences that the American Moshan stone and the domestic Moshan stone are different in color, fire color and permeability.

What is the difference? I suggest shopping around. Physical comparison is the most intuitive.

Ps: To buy imported Mosan stone, it is recommended to buy it from an official authorized dealer.
