Turquoise identification teaches you to identify true and false at seven points:

1. soaking method: this will only test whether it is foam pine or porcelain pine, and it has no decisive role in authenticity. Bubbles are loose, and bubbles will appear on the surface of turquoise when it meets water, which will change color after a long time, but higher-grade porcelain will have no effect.

2. Listen to the sound: Jade's voice is generally crisp. As long as it is processed, it is boring, not only turquoise, but also jade. If you listen to it too much, you can naturally hear it.

3. Look at hardness: high porcelain turquoise, its hardness is similar to that of glass, and some can even scratch glass. The foam is light in color and low in hardness, so you can paddle with coins. If the color is very light, but glass can be scratched, it is probably glue injection. Porcelain pine can not be scraped with a knife, and hard pine can be scraped with a knife to remove a small amount of powder. If it is dry turquoise, what is scraped with a knife is rolled up and stuck.

4. Look at the luster: The appearance of turquoise has waxy luster and oily luster. It is common in the market, and different grades of turquoise have obvious differences in texture and luster. The better the brightness of turquoise, it proves that the harder the goods, the better the quality of turquoise will have the feeling of glass and some transparency.

Blue is better. If the foam is not optimized, it will feel sticky with wet hands, but it is not cold.

Look at the net pattern: iron wire is also one of the distinguishing features of turquoise. Good turquoise patterns and colors are beautiful and accord with people's aesthetics. Good turquoise should be bright, not dull. The beautiful turquoise of spider web can also be a good product, and Wulanhua and Netflower are among the top grades.

6. Look at the color: the easiest place is its color. The unique color of turquoise is due to the chromogenic ions it contains. Turquoise tends to be blue when it contains more copper ions. Turquoise is often green when it contains more iron ions.

7. Burning method: If it is fake turquoise, it will have a pungent smell when burned, but it is not natural.
