1. Theory of artificial fraud: For the red agate of the Warring States period, it is basically impossible to make artificial fraud, and no one does it at present, because it is very difficult to make artificial fraud because of its gorgeous colors, heavy texture and three-dimensional silky feeling. During the Warring States period, the texture and living silk of red agate are difficult to imitate, and the color will become ugly if the temperature is slightly deviated. So when you're sure it's Warring States Red, it's basically natural!

2. Chicken liver stone is an impostor: the difference between Zhan Guohong and chicken liver stone: the silk on chicken liver stone is just a black line, and occasionally there are white lines, which grow on the surface, and the overall color and texture feel stiff! Careful observation shows that the chicken liver stone is only smooth on the surface and can't see the internal moisture! On the other hand, the color of national war red is from the inside out, and many silks are living silks. You can see that silk grows vertically in agate. The color is also moist and transitional!

3. The most obvious difference between tricolor jade and red agate in Warring States is that tricolor jade has the luster of jade, while red agate in Warring States has the luster of glass. Especially in the white part, it is obvious that jadeite and agate can be distinguished!
