As long as there is a market, there must be counterfeiting, and for the purchase of jade jewelry and other literary games, it is not careful to be found by fakes. In recent years, the market of Nanhong agate is booming, and the methods of counterfeiting, whether it is raw stone or finished product, are even more difficult to prevent. Today, let's talk about the identification method of raw stone of Nanhong agate. We must carefully select and identify the raw stone of Nanhong agate.
How to distinguish true from false
At present, the raw stone counterfeiting of Nanhong agate in the market mainly depends on the cement counterfeiting method. Bad merchants will use cement to repeatedly mix the crushed stone material similar to volcanic ash, and then wrap it on the surface with fragments of natural South Red Agate raw stone, so as to imitate the red skin and opening of natural south red agate.
This method of using cement to imitate natural South Red Agate sounds magical, but it has cheated many players. So today we will talk about the identification method of South red agate.
1. Look at the skin shape
The natural south red agate is formed during volcanic eruption, so its high-temperature burned skin is generally rough, with clear and visible texture, beautiful and natural texture. On the other hand, for the raw stone of South Red Agate made of fake cement, the grain of its outer skin is generally unnatural, and there are no natural edges and corners. Its roughness is also unnatural, and there are artificial protrusions.

2. Look at the color
Color is the most important point in the identification of raw stone of South red agate, because the skin color of natural raw stone of South Red Agate is very rich, including yellow, red, black, blue, brown, green and other mixed tones. But the false stone skin is generally black gray, after washing, there will even be color fading, gray and other phenomena, the color of the opening part is also very uneven, color floating.
3. Light up and observe
Even if the natural red stone has skin and pulp, it can still see the halo under the lamp. And there won't be any halo under the light of the fake south red stone.
