In particular, the ring surface requires the highest hardness and the best quality of the ring surface fabric, so the jade surface should have a mirror effect, the surface light should be like a portrait, and the variety should be enough.
In addition to color, the type of torus is also very important. Emerald rings with light are relatively more valuable. If you collect them, it is more important to choose bright ones. In terms of material selection, the requirements for making ring faces are higher than those for making other jadeite products. Cracking, white cotton, black spots and other problems can be regarded as the shortcomings of the torus.
The torus size has a key influence on the price. If the ring is bigger, the price may increase exponentially. Sixth, look at the polished jade egg surface. Brightness and beauty can be increased after polishing.
Why can't jadeite be polished to a mirror effect?
The most important thing is that the mirror effect will never be achieved, and the brightness is 20% worse than that of jade pieces sold in shops.
After jadeite polishing, it is necessary to use ultrasonic machine to clean the residual polishing powder, and the part that cannot be cleaned can be wiped with alcohol. Finally, wax the jade, and then dry it with a hair dryer, and the jade can show a mirror effect.
Jade seeds are tender and dull, and can be waxed. Because waxing after jadeite polishing can polish and smooth the jadeite surface, to a certain extent, make the jadeite surface more uniform and smooth, and improve the gloss and transparency.
How to distinguish between the old species and the young species of jadeite?
1. Carefully observe the sand (turned sand) on the weathered crust of jadeite original stone, and feel its texture by hand. If the sand is upright, evenly distributed, hard and rough, it is old jade. On the other hand, if the sand is not prominent enough, unevenly distributed, soft in texture and easy to fall off, then this is the original jade stone.
2. Listen to the sound to distinguish the old and tender jadeite. You can listen to the sound. The hardness of old jadeite will be higher than that of young jadeite. When you tap the jade with chopsticks, the sound is crisp, indicating that the jade is old, but the sound made by the tender jade will be slightly dull.
3. Jade's viewpoints are: observing shells, splashing water, observing fog layer and so on.
Jade can be judged by luster, texture and cotton.
5, hardness, the hardness of jadeite such as old species is higher, and the hardness of young species is relatively low. Hit the jade with a hard object. If it is old, the voice will be crisp, while the voice of tender jade is dull.
Is the jadeite polished and thrown into the mirror the same as the real thing?
1, vibration polisher, magnetic polisher and roller polisher are all kinds of polishers. Adding brightener and polishing particles to it can realize mirror surface, but the mirror surface effect is very poor, which can't be compared with manual polishing. There is also a kind of rotary socket polishing, by the way, the average customer does not accept this effect. .
2. The refractive index of jadeite is above the middle, so the polished surface of jadeite will have a strong luster under the reflected light. Some fakes, such as quartzite jade such as Dongling stone, are obviously not as shiny as jadeite.
3, polishing depends on the structural quality of the material itself is hard enough, like a mirror, it should be rigid, or it has a feeling similar to gluing, which proves to be good.
Is it possible to polish the jade surface like a mirror?
Vibration polisher, magnetic polisher and roller polisher are all kinds of polishers. Adding brightener and polishing particles can achieve mirror surface, but the mirror surface effect is very poor, which can't be compared with manual polishing. There is also a kind of rotary socket polishing, by the way, the average customer does not accept this effect. .
After jadeite polishing, it is necessary to use ultrasonic machine to clean the residual polishing powder, and the part that cannot be cleaned can be wiped with alcohol. Finally, wax the jade, and then dry it with a hair dryer, and the jade can show a mirror effect.
The mirror effect of jadeite polishing is that the polishing effect of jadeite surface is full of luster, just like a mirror.
What does jadeite think of growing water?
Look at the gray level: usually the old jadeite with good water head always has a little gray. Look at the fluorescence: Old jadeite with good water quality sometimes feels a kind of light radiating from the inside of jadeite, which is soft and meaningful. Due to the tight texture and delicate structure, the old material will be as bright as new even if the surface is polished.
Observe the sand grains on the surface of jadeite. If the sand grains on the surface of jadeite are upright, and the sand grains are evenly distributed and hard, it means that the seed water of jadeite is old and belongs to old jadeite. Pour water on the jade skin.
You can see cotton when you grow jade bracelets. Generally speaking, jade bracelets with long water contain less cotton. Even if there is cotton, it is presented in tiny dots. But the tender jade bracelet will have more cotton, and it will be accompanied by a lot of ice slag and the like.
