With the popularity of Mosan diamonds, people's attention to diamonds is not limited to the identification of authenticity, but the quality classification of Mosan diamonds. The 4C principle is usually adopted internationally, namely:
Carat weight: 1 carat equals 200 mg.
Clarity: It is divided into six grades: FL, IF, VVS, VS, SI and I, and the market is mostly Si-VVS.
Color: from d, e, f, LLN and cut: it is divided into very good, very good and general.
Knowing the classification knowledge of Mosang diamonds is helpful to buy Mosang diamonds with reasonable price and high quality.
The quality of colored gems, such as ruby and sapphire, depends on its color, transparency, flaws, cutting and other factors. To clean gems and jewelry, generally take a bowl of warm water, add a small amount of detergent, gently dip it in the water with a small brush, then rinse it with water, then absorb the water with a cloth and dry it with a soft silk cloth. When storing gem jewelry, be careful not to put all the jewelry in one box at the same time, because the gems embedded in the jewelry will rub against each other, which will damage and lose their luster.
Remember the quality standard of a diamond -4C.
"4C" is the yardstick for you to judge the value and quality of a diamond. The so-called "4C" is the abbreviation of four English words beginning with C, which refers to the carat weight, clarity, color and cut of diamonds. You can easily understand the value and quality of a diamond just by appreciating the four points of "4C". The price of Mosang diamond ornaments = weight+color+clarity+cutting.
Carat weight
The weight of Mosan diamond is calculated in carats. 1 carat = 200mg = 0.2g A carat is divided into 100 parts, each part is called one point, 0.75 carat is 75 points, and 0.09 carat is 9 points. Under other similar conditions, with the increase of the weight of Mosan diamond, its value increases geometrically; Mosan diamond with the same weight will have different values due to different colors, cleanliness and cutting.
CLARITY (clarity)
Mosang diamond is crystallized from mantle magma deep in the earth. After hundreds of millions of years of geological changes, it inevitably contains various impurities and defects. The color, quantity, size and location distribution of these inclusions have different degrees of influence on the clarity of Mosang diamond. Generally, the internal and surface defects of diamonds and their influence on the brilliance are analyzed with a magnifying glass with a magnification of 10. The clarity grades of diamonds without diamonds are subdivided into LC, VVS 1, VVS2, SI 1, SI2, P 1, P2, P3 * * * 65438.
Color (color)
Mosan diamonds have many natural colors. From precious colorless (white after cutting and grinding), rare light blue and pink to common yellowish. The more transparent and colorless, the more white light can penetrate and become more colorful after refraction and dispersion.
The color grading of Mosang diamonds is determined by technicians repeatedly comparing the diamonds to be graded with standard color colorimetric stones in the grading environment of professional laboratories. The color of Mosang diamond is divided into 1 1 grade, which is divided into: D, E, F, G, H, I, J, K, L, M and N in turn.
Cut (cut)
The brilliant brilliance of Mosang diamond is attributed to its unique high refractive index and high dispersion performance. Mosan diamond is the hardest substance, indestructible and will never wear out. Once it is cut and polished, it will shine forever. The way to judge the quality of diamond cutting is to pick up the Mosan diamond and stare at the jumping light at the top. The exquisite Mosan diamond by the lathe worker is dazzling, and its brilliance will not disappear because of inlay or different styles. The lathe worker's level is: very good, not bad, just so-so.
