Enter the jade processing factory and see the entire process from jadeite raw stone to bracelet at close range

What we usually see are flawless jade bracelets.

But how was this bracelet made?

1. Polishing Stone

Rub a hole on the surface of the raw stone to make it easier to shine a light on the inside and observe whether there is green, as well as the depth, width and concentration of the green.

Then, judge whether the raw stone can be made into bracelets based on the cracks, and then consider pendants, ring faces, and beads. Bracelets can be said to be the essence of jadeite raw stones.

2. Cutting Stone Slices

After having a preliminary understanding of the raw stone, you need to cut the raw stone and then slice it. After cutting, you need to judge whether the bracelet is “selling color” or “selling water quality”.

Although this step is only judged based on existing experience, it is crucial. It not only determines the performance of the bracelet, but also determines subsequent transactions and income.

3. Draw the bracelet ring print

After the raw materials are sliced, the size of the bracelet is determined based on the cracks, size, and color distribution of the raw materials to ensure that the type and color of the bracelet are optimal and the output is maximized.

This step requires a thorough understanding of market conditions, not only knowing the prices, but also observing and studying the preferences of buyers.

4. Absorbing the ectoembryo

Place the jade piece with the bracelet position drawn on it on a special diamond lathe, match the corresponding drill bit according to the outer ring diameter, and then use downward pressure to suck out the entire bracelet, which is called "sucking the outer embryo" in the industry.

5. Check the Bracelet

After sucking out the outer embryo of the bracelet, you need to check whether there are impurities, color changes, and cracks caused by the processing process. Once the inspection is complete, proceed to the next step.

6. Sucking Endoderma

According to the diameter of the inner ring of the bracelet, select the corresponding drill bit, and then use the downward pressure drill to suck out the inner ring, which is called "sucking the inner embryo" in the industry, and the middle part sucked out is called the "bracelet core". After this step you will get a rough bracelet.

When sucking out the ectomorpha and endomorpha, try to keep the jade slab moist, otherwise the jade will crack easily.

7. Top and side shots

Topping is to remove the defects and cracks of the rough piece, and edging is to remove the edges and corners of the bracelet and grind it into a smooth state.

8. Punching embryos

The rough bracelet is ground into shape according to needs. The curvature angles of round bracelets and flat bracelets are different, so the angle and strength when punching the blank are also different.

Manual punching is suitable for high-end bracelets, while punching by a molding machine is suitable for mid- and low-end bracelets.

9. Polishing

Grind the marks on the rough bracelet blank into a smooth surface and completely shape it from the inside out.

10. Polishing

Sand and polish the polished bracelet, back and forth several times until the bracelet reaches the desired brightness.

What we usually see are perfect bracelets, but behind this there are more than a dozen processes, and a lot of material is worn away step by step, and there is no way to use the scraps.

At the same time, this is also a very big test of experience and processing technology. If a mistake occurs in one step, all previous efforts will be wasted.

Five tips for choosing jade bracelets

1. Types of jade bracelets : When buying jade bracelets, we must first look at its type. Bracelets can be divided into round bars, flat bars, round bars, imperial concubine bracelets, and can also be divided into several types such as carved and plain ones. Round bar and flat bar refer to the shape of the bracelet's cross-section, round and imperial concubine shape refer to the shape of the bracelet's front, and carved and plain refer to the shape of the bracelet's appearance. When insiders talk about the thickness of the bracelet, they are referring to the width of the bracelet wall. It is worth mentioning that most of the carved jade bracelets we encounter have cracks on the surface and need to be modified by carving. For example, the bracelet with two dragons playing with a pearl (two dragons next to a pearl) looks very beautiful, but its cracks are very serious, so it is not worth collecting. As a collection-level bracelet, it should have a plain shape.

2. The color of the jade bracelet : First, we have to look at the amount of color it has, which has a direct impact on its price. The price of a little color and a large range of color will vary greatly; secondly, we have to look at the color intensity. The prices of colors with different intensities will vary greatly; thirdly, we have to look at the brightness and darkness of the color. Bright colors will be sold at a very high price. The color is relatively dark, and the price will be much lower. The above two points are usually noticed by buyers when purchasing jade bracelets, but the gathering and dispersion of colors is a problem that is relatively easy to overlook.

3. The base of the jade bracelet : The types and colors of jade bracelets are what most people will pay attention to when purchasing jade bracelets, but the most important and easiest to misjudge when looking at the bracelet is its base (the base is the part other than green). Usually, the green part of jadeite will be of good quality and very transparent. However, the non-green parts will be particularly dry and not transparent. This is what insiders call "where the dragon is, there is water"). Two bracelets with the same green part may have a huge difference in selling price due to their different bases.

4. Cracks in jade bracelets : The cracks in jade bracelets are relatively easy to see when held up to the light, but sometimes the stone patterns and color lines in the bracelet can easily be mistaken for cracks, so buyers need to identify them in practice. Jade that looks flawless on the outside may very well be of poor quality. It is not easy to see the problems inside the jade at this time, and it is also easy to make mistakes when purchasing jade bracelets. The better the quality of the jade, the whiter the inside, and the more obvious signs such as cracks are. Therefore, the cracks in the bracelet should be taken seriously when purchasing jade bracelets, but they should not be overemphasized.

5. The shape of jade bracelets : Bracelets of the same type and color will have different selling prices due to their different widths. Generally speaking, the price of wider materials is higher. The thickness is reflected in the height of the bracelet's cross-section. A high-quality bracelet must be relatively thick and quite full. The inner diameter of a hoop bracelet can also affect the selling price. For bracelets of the same type and color, the larger the circumference, the higher the price. In general, bracelets with fine and transparent quality, bright and pure color, simple shape, thick material and no cracks are extremely collectible.
