Learn how to look at jadeite under light, and you can also be very professional!

Whether we are in the jade live broadcast room, the counter selling gemstones, or in other jade markets, we can find that they basically have flashlights. So what are the flashlights used for?

I believe everyone knows that flashlights are used for lighting. But there are also many people who are confused and wonder what the lights are looking at? How to choose the flashlight light? Which flashlight should I use? ...and many other questions, so let’s find out and learn how to light professionally!

First, let’s take a look at how to choose a flashlight.

To light up jade, you naturally need to use a flashlight specially designed for jade, and you also need to pay attention to the color of the light. Flashlights specially designed for jade are divided into strong light, weak light, yellow light and white light. When looking at jadeite raw stones, we recommend that you choose a yellow strong light flashlight. This type of flashlight has stronger penetrating power. Under this light, we can better observe the internal situation of the jadeite.

When looking at finished jade products, it is best to use a strong white flashlight to observe them, because the finished products have been ground and polished, some parts still have a thin layer of wax, and the jade may have its own color, so only white light can see the true color of the jade.

Now that we know how to choose a flashlight and what kind of light to use, how do we actually turn on the light? Come and see!

Direct light to see the texture

Point the flashlight directly against the surface of the jade to mainly observe the texture and thickness of the jade. When a strong flashlight is shone directly on the surface of jadeite, the Hetian jade appears translucent, and the light is relatively concentrated.

However, the halo when shining directly on quartzite, marble, or glass mixed products is relatively scattered.

When a direct flashlight moves slowly horizontally, you can observe whether the texture and structure of the jadeite is uniform. If the light transmittance of the jadeite is uniform when the flashlight moves horizontally, it means that its structure is uniform. If the light transmittance is uneven, it means that the structure of the jadeite is not uniform.

Light is slanted to see the density

The quality of jade is an important factor in determining its value. As the saying goes, even gods cannot tell the quality of jade, but with a flashlight, we can see some clues. The oblique light of a strong flashlight is an important means of identifying the grain size and density of jade texture.

But what needs to be noted here is that the angle of oblique lighting is very important. We should try to shine the flashlight at a 45° angle, and try to illuminate the skinless areas. Moreover, the oblique lighting does not mean looking at the jadeite closely. The flashlight should be placed 3 to 10 cm away from the surface of the jadeite for illumination.

We should try to illuminate at multiple points, or we can use the method of slowly moving a single point in parallel or far and near to observe from multiple angles until the floc structure is clearly seen. In this way, we can judge the fineness of the jade's internal texture.

Backlighting to see flaws

Back shooting is to place the flashlight close to the back of the jade, and then we observe it from the front. In this way, we can clearly see whether there are impurities, cracks and other defects in the jade. We also need to move slowly horizontally to observe from multiple angles.

When there are impurities in jade, dark spots will appear inside. If there are cracks inside the jade, a dark reaction will appear when the flashlight light source is moved horizontally, or uneven refracted light may be seen. Just pay attention and observe carefully.

Now that you have learned these methods, if you have the conditions, put them into practice.
