A complete evaluation of a diamond can only provide the most detailed quality information by relying on the 4C certificate of diamond appraisal. I'm afraid this is not what you want to hear. Here are some simple and easy-to-operate identification methods. I wonder if I can help you:)
In daily identification, there are two simple ways to identify the authenticity of diamonds:
1. Line test:
Clean the diamond, put it on a piece of paper, draw it with a line, and the table is facing down. If the proportion of diamonds is good, no lines can be seen through the diamonds, while most imitations allow enough light to pass through, at least some lines can be seen.
2. Water drop test:
When the diamond pen is crossed on the surface of the diamond, the ink will leave lines. If it is an imitation, the ink will gather into droplets.
In addition, water drop test can also be used. On a diamond with a clean surface, the water will remain spherical for a long time, while the water on an imitation will disperse in a relatively short time.
These simple methods can help consumers to preliminarily judge the authenticity of diamonds, and the detailed quality needs to be tested and graded by professional laboratories.
First of all, clarity
FL is flawless.
If it is immanent, the surface is slightly flawed.
VVS 1。 VVS2 contains tiny inclusions (tiny defects invisible to naked eyes).
VS 1。 VS2。 Contains tiny inclusions (tiny defects invisible to the naked eye).
Si1.si2. Small inclusions (invisible to naked eyes)
I1.i2.i3. Inclusions (visible defects)
Second, color.
The color grading of diamonds is divided into 23 grades from English letters D to Z.
D, e and f belong to the colorless range;
G, H, I and J belong to the near colorless range;
K, l and m are yellowish;
Below n is light yellow.
Diamonds need professional knowledge and experience. If you are only interested in it, I believe my answer can help you.
