How to distinguish true and false turquoise

How to distinguish true and false turquoise

Turquoise has been one of the favorite gems of the Chinese people since ancient times. It also has a long and splendid history in our country. During the Qing Dynasty, turquoise was called the gem of heaven, symbolizing victory, good luck, and success. Popular, many people also like to use turquoise as a decorative stone. Nowadays, the price of turquoise is soaring all the way, but the high price has also increased the fraud in the turquoise market, but the editor introduces 5 simple ways to distinguish turquoise raw ore, I hope it will be helpful to everyone!

How to distinguish true and false turquoise 1

1. Distinguish water immersion and observe air bubbles

No matter how dense the turquoise is, there will be tiny pores. Therefore, we can use this to confirm whether turquoise is a raw ore. We can soak half of it in water. After a period of time, if it is a real turquoise ore, the contrast will reveal a difference in color.

In addition, the real turquoise ore is immersed in the water for about an hour, and the surrounding area is generally full of fine and small bubbles. The higher the porcelain degree, the longer it takes for the bubbles to appear. If it is a collagen injection stone, since the pores on its surface are sealed by glue, naturally there will be no bubbles.

 

2. The identification of fluorescent lamps has limitations

The turquoise injected with glue in the early days can be identified by fluorescent light, because the glue will fluoresce under fluorescent light, but the latest glue injection technology has no fluorescence under fluorescent light. Therefore, the identification with fluorescent lights is very limited and can only be used as a simple reference.

3. Instrument testing, reliable and authoritative

If the fluorescent lamp shows that there is no fluorescence, first we can use a magnifying glass to observe the cracks to determine whether there is glue in the iron wire. If you are not at ease, then use infrared spectroscopy to detect, authoritative and reliable!

4. listen to the sound, look at the color

The authentic turquoise ore can produce "porcelain sound" when colliding with each other, which is crisp and sweet. However, the turquoise density and porcelain of the glue are relatively poor, and the sound will be dull and not crisp enough if they collide with each other. In terms of color, because the color of rough turquoise is produced by the action of color-causing substances such as copper and iron in the body, it is basically not particularly consistent, and it will appear natural in depth and light; while fake turquoise will be colored because of the color. So it looks uniform and dull.

5. Scratch identification, simple and useful

The turquoise injected with glue is usually relatively low in hardness. Therefore, when using this point of identification, use a needle or a knife to scratch the turquoise hole, engraved horizontal and other inconspicuous places, which is very prone to scratches. In some areas where the glue is thicker, lightly scraping with a razor blade will cause slight peeling.

Conclusion: The above 5 simple turquoise identification methods can effectively eliminate most of the fake turquoise. If it is expensive turquoise, of course it is more appropriate to send it to an authoritative testing agency. The rough turquoise stone is a beautiful treasure bestowed by nature. To identify the rough turquoise ore, we must comprehensively judge from many aspects, and must not be easily determined!
