The "4C" Standard of Diamond
Diamond, a product from nature, is also a valuable stone. Diamonds are loved by lots of people, especially female. For them, having a diamond ring is a very happy thing. However, there are many people still not know how to choose a diamond ring. In fact, the key to selecting diamonds is the 4C standard for diamonds.
"4C" standard is a measure of the value and quality od a diamond. The so-called "4C" is the abbreviation of 4 English words that begin with C, referring to Carat's weight, Clarity, Color, and Cutting.
First of all, let's look at the carat’s weight. The diamond has its own weight unit, which is carat. Diamond weights are calculated in carats. 1 carat = 200 mg = 0.2 g. Under similar conditions, as the weight of the diamond increases, its value increases geometrically. Diamonds of the same weight will have very different values due to differences in color, clarity, and cutting.
Secondly is clarity. It is also the transparency of diamonds. The diamonds are crystallized in the mantle magma deep in the earth. The environment is complex and the composition is varied. The inside of the diamonds inevitably contains various impurities or defects. The color, amount, size, and location of these impurities affect diamond clarity to varying degrees. With a 10x magnifier, the clarity of a diamond is usually graded by the diamond's interior, surface defects and its effect on brilliance. The more transparent the diamond, the higher the clarity.
Thirdly is color. The diamond is divided into several colors, the transparent color, sky blue, bright red. Everyone can choose the color of the diamond according to their favorite color. The whitest diamond is rated D (starting with Diamond's first letter). Diamond color is divided into 11 levels, by: D, E, F, G, H, I, J, K, L, M, N.
The last and very important point is the cutting. It can be said that cutting is a crucial step in determining the diamond shining in the sun. A good cutting should reflect the brightness and fire of the diamond as much as possible, and try to keep the original stone weight.
