How many commonly used jade identification tools do you know?

In the jade market where good and bad jades coexist, if you want to buy genuine jade, you need to be well-educated and know how to use various tools to identify jade. Well, these jade identification tools are very common, come and brainwash you!

magnifier

In fact, there are regulations for choosing a magnifying glass. A 10x magnifying glass is best. When identifying jade, it will not affect the observation of the jade. It also helps us see whether there are more impurities inside the jade, or whether there are subtle flaws that are sometimes invisible to the naked eye.

Focus Pen Flashlight

Among the methods of jade identification, the method of using light illumination to identify the texture of jade was proposed. A spotlight can be illuminated to reveal the internal structure and inclusions of a gemstone, as well as the refractive effects on the surface. For example, a good water-type jadeite will produce fluorescence on the surface under light, which is called glue. Therefore, this flashlight is a necessary identification tool and is easy to carry.

Electronic balance

We know that different types of jade and jewelry have specific densities. An electronic scale can be used to determine the authenticity of jade by testing its specific gravity. Don't underestimate this tool, as natural jade and imitations or other kinds of jade, their respective proportions are different, and we can effectively identify the jade based on the numbers shown. But the electronic balance is a bit big, so it is not easy to carry around.

UV fluorescent lamp

This is a product of high technology, not everyone has it. By observing the color of jade under ultraviolet fluorescent light, you can determine the type of jade jewelry, see whether it has been artificially optimized, and identify its origin. Of course, professional knowledge is indispensable in the identification process.

Refractometer

Various jade jewelry has different refractive indices. For example, the refractive index of jadeite is 1.66, the refractive index of tourmaline is 1.624-1.644, etc. The refractive index of jade can be read and measured quickly and accurately by a refractometer. With this foundation, we can preliminarily identify the properties of jade. Of course, in order to obtain more accurate identification results, we can also refer to other identification methods.
