The internal structure, numerical value and appearance of Mosan stone are strikingly similar to diamonds. Even if it is detected with a diamond pen, it will be judged as a diamond, which is difficult to distinguish. However, mosang stone can shine more than diamonds, and the fire color is more amazing. At the same time, the price is only110 of diamond.
The fire color of Mosang stone is so beautiful because of its physical, chemical and optical properties. This gem has a very high refractive index of 2.65-2.69 (2.42 for diamonds), a dispersion coefficient of 0. 104 (0.044 for diamonds) and a luster of 20.4 (17.2% for diamonds).

Identification method:
1. If the attribute appears before "diamond": Su diamond, Mosan diamond, Swiss diamond, Thai diamond, Australian diamond, crystal diamond ... are just substitutes or imitations of diamonds.
2. Diamond detector is the fastest and most accurate tool to detect diamonds, except mosan stone. But there is a "synthetic moissanite detector" that can detect mosan.
3. Put "Su Anzu" on a straight line, and you will see an "O" by observing the straight line through the sample; However, under the magnifying glass of 10 times, mosangshi will appear ghost at some angles.
4. Buy diamonds from regular channels and find out whether diamonds have certificates issued by qualified laboratories.
5.NGTC, commonly known as State Inspection, is the most famous in China. Guangzhou Entry-Exit Inspection and Quarantine Bureau comprehensive technical service center jewelry appraisal laboratory also has authoritative certification qualification.
6. To measure whether the laboratory is qualified and whether the certificate issued by it has legal effect mainly depends on whether it has CNAS accreditation and CMA certification qualifications.
7. Certificates are sometimes false. However, there is usually a code on the certificate, which can be distinguished by logging in to official website.
8. At present, the most famous certificate abroad is the GIA certification of American Gemological Institute. But the risk of buying diamonds overseas will be greater, so we should pay great attention to the differences between English expression and Chinese expression.
