Agate, also known as "Qiongyu" in ancient times, was often used to make jewelry, carvings and other crafts, especially agate bracelets, which can be said to be one of the most common jewelry in Chinese life. However, there are also a lot of fake agate bracelets on the market, so today we are going to talk about how to identify the genuine agate? Agate true and false identification methods to understand.
Look at the banded structure
The first way to identify agate bracelets is to look at the banded structure, which is the biggest feature of natural agate and the most significant difference from fake agate. Generally speaking, natural agate will have concentric layered structure. Of course, there may not be any finished products after cutting. However, for agate bracelets, because there are many beads, it is impossible to have no stripe on each bead. If there is no stripe on each bead of the whole string of agate bracelets, it is likely to be fake agate made of plastic or glass.
Moreover, banded pattern is also the key factor to distinguish agate and chalcedony. Both agate and chalcedony are mineral aggregates dominated by cryptocrystalline quartz. Those with banded structure are called agate, while those without banded structure are chalcedony.
Look at the color:
For the identification method of agate bracelet, the second thing to see is the color. Because natural agates are lighter in color, artificial dyeing is also very common in the agate market, especially for red, blue and purple agates, almost 90% of which have been dyed. So if the agate bracelet you buy is very colorful and the color of each bead is very uniform, it is very likely that it has been dyed. Because the color of natural agate is lighter, and the color of each bead will be different.
See transparency and luster:
The third point of the identification method of agate bracelet is to see the transparency and luster. Natural agate is the product of underground magma eruption and cooling, so it has a strong sense of colloid. The surface seems to be coated with a layer of wax, with slightly chaotic luster and translucent to opaque. Many fake agates are made of stone, with dull luster and no lustrous feeling. Some glass products are of strong luster, and small bubbles can be observed with a magnifying glass.
