Agate is naturally colored and artificially dyed. How to identify dyed agate?
To identify dyed agates, see the following:
First, the color
Natural agate color is natural, the boundary between the ribbon and the ribbon is obvious, clear and sharp, so the layering is strong. The color of the dyed agate is too bright and rigid, not fresh, the boundaries between the ribbons are not clear enough, and sometimes there are transition colors.
Second, the texture
The agate itself has a strong texture, a hard texture and a compact structure. The natural texture is very clear, and the dyed agate is manually treated, the internal structure is destroyed, the appearance is changed, and the texture is damaged, so it is not very obvious.
Third, the texture
The agate has a high hardness. Generally, a slight collision will not leave a scar on the surface. In contrast, the dyed agate itself is damaged by the texture, and the hardness is low. After the collision, some traces will be left behind.
Fourth, transparency
The transparency of agate is not high, it can be said that it is not transparent. Therefore, it is not obvious to the inside when it looks at the light. The dyed agate is different, its internal structure changes, the transparency is relatively high, and some can be seen. Structural condition.
In addition to these four points, the identification of dyed agate can also be compared with its specific gravity, sound, craftsmanship, price, etc., and can also compare the difference between natural agate and dyed agate.
