How to identify jadeite?

Identify by the color and luster of the surface. Real jadeite feels smooth by hand and looks shiny in the sun. The pattern inside is also exquisite, which has a cool feeling.

The method of distinguishing true and false jadeite: color root. The color root is slightly dark green with a little or a thin band. Among these colors, slightly darker green gradually transitions to relatively lighter green. The color and foundation of natural jade A goods are natural and generous, and the green is distributed in roots or blocks, with clear and clear outline. Emerald

According to the color, density, smoothness and convexity of the epidermis, we can roughly estimate the internal color of jadeite raw materials, the quality of water head, the quality of land, the old and tender types and the number of cracks.

There are ingenious methods to identify jadeite, and it is enough to master these methods: ultraviolet irradiation to identify jadeite is to irradiate it with a flashlight to see if there is any fluorescence reaction.

2. The first case may be due to long-term wear and tear. After a long period of friction, the wax protective layer on the surface of the jade bracelet was wiped off, and the jade surface also lost its protective layer.

3. It has been left for too long. The white cotton of jadeite refers to the "floc" in jadeite, which is the phenomenon that some cotton-like substances appear in jadeite under the side light or bottom light, also known as "cotton".

... and a little yellow jade scattered. Is this collectible? Ask an expert to evaluate the price.

You can make a comparative reference.

3. Such high-quality yellow jadeite is very rare, so its value is also very high, and it has excellent appreciation space. Therefore, this yellow jade carving is very collectible.

But this does not mean that the value of yellow jade is not high. On the contrary, the price of yellow with well-planted water and uniform color distribution is actually lower than that of green jade. For example, this yellow jade Guanyin sold for 402,500 RMB in Sotheby's Hong Kong Spring Auction.

But the quality of most yellow jadeites is not very good, especially in terms of planting moisture. Yellow jadeite with good planting water is extremely rare and of high value.
