Mosang diamond is the second hardest gem in the world (Mohs 9.25), only lower than South African diamond (Mohs 10) and higher than other gems, and it is the second hardest gem in the gem world.
Moshan stone was cultivated in a specific high temperature and high jade environment for nearly ten months. GIA authorities identified that the internal structure, value and appearance of Mosan diamond are strikingly similar to diamonds. Mosan diamond has the optical and physical characteristics of South African diamond, and its brightness and refractive index are higher than that of South African diamond, which is more than 2.5 times that of South African diamond. It is the brightest gem in the world.
Precautions for beginners in selecting Mosan diamonds:
Anyone who knows about diamonds knows that 4C parameter is the only criterion to judge its value, and it also applies to Mosan diamond.
What is 4C? Refers to the abbreviations of four English words starting with C, namely carat weight, cut, clarity and color. The weight factor accounts for about 40% of the price, and the other three items each account for 20%.
weight
When selecting Mosan diamond, the first consideration is weight. The more carats, the less quantity and the higher price. Our most common is 1 carat Mosan diamond, and those less than one carat are also called fenn. 1 carat = 100 carat =0.2 gram, for example, 75 carat is 0.75 carat.
When choosing carats, the bigger the size, the better. It should also be decided according to your own budget, the matching degree between different sizes of Mosang diamonds and different bases, and the hand type of the wearer.
colour
Whether it is diamond or Mosan diamond, its color grade is colorless. The more transparent the color, the more beautiful the fire color reflected by light penetration. The highest grade Mosan diamond is classified as D (the initials of diamond). The farther the letter goes, the closer the color of Mosan diamond is to yellow, indicating the lower the color grade. When purchasing, the first choice is D-grade Mosan diamond.
When you look at the color of Mosan diamond, you must look at it on a pure white background, so that the color is easier to see. Generally, the larger the Mosan diamond, the more obvious the color.
clean
Diamonds are natural products, so the clarity varies greatly. Diamonds with high purity are very rare, and diamonds that can reach VS level are even rarer. Therefore, even tens of thousands of diamonds are still flawed. Moss diamonds are different. Because it is cultivated in the laboratory, the clarity of Mosang diamond is still excellent even if it is observed under a magnifying glass of 10 times.
According to China's national inspection standards, the clarity of Mosang diamond is subdivided into LC, VVS 1, VVS2, VS 1, VS2, SI 1, SI2, P 1, P2, P3*** 10. Diamonds are divided into five grades: excellent, very good, good and good. It is generally recommended to buy Mosan diamonds of SI and above.
incision
The most important thing to judge whether the Mosang diamond is cut well is whether its cutting-grinding ratio is accurate and its decoration is perfect. In this way, all facets can reflect all external light, so that the fire color of Mosang diamond presents the most beautiful effect.
