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.
