There are many kinds of jewellery identification: diamond identification, jade identification, jade identification, etc. No one can subdivide many categories, such as material identification, crack identification, etc., so jewelry identification is a very troublesome and delicate work. .
Why do you want to identify jewelry? I think everyone knows that jewelry itself has a high value and charm. Often a piece of jewelry is worth a lot of money. If you buy a fake, the loss cannot be estimated, so there is a jewelry identification industry.
If you buy jewelry regularly, or people in the jewelry industry, it is necessary to know more about jewelry identification. Below I will talk about the identification of jade .
First, the quality of jade is from the first sight to see the beginning, so the first procedure for jewelry identification is "look" !

Flies are often seen on jade that has not been polished.
I think that everyone should see the jewels at the first sight of the jewels. When observing the color of jewels, pay attention to the quality of the jewels. Generally, the jewels will have a smooth surface and a soft and beautiful color. Careful observation will lead to unnatural phenomena, because jewelry is generally generated by nature, so it should be natural and beautiful, and general artificial jewelry can not do this effect.
Second, when you let a jewellery color attract you, you will let the salesperson take it out and let you take a closer look. This is in contact with the jewelry, so the next appraisal procedure is "feel".
