Jadeite setting method

The inlay technique is naturally very important. Inlay is a delicate technique that combines wrapping and chiseling. The tools used must be handy and dexterous, and the auxiliary raw materials must be appropriate and moderate. Jewelry made by inlay technicians with high craftsmanship should have good luster, prominent colors and complete shapes. The specific welding is simple, the stone body and the base are tight and seamless, the carvings and patterns are clear and powerful, and the overall layout is both coordinated and regular, vividly and truly reflecting the essence of the design concept, making it a gorgeous and sophisticated work of art. On the contrary, products with low craftsmanship will definitely have a dull surface, holes or bubbles in the welds, they will be crooked, and the specifications will be too large or too small. It is completely different from the design. At first glance, it looks like an inlay, but upon closer inspection, it is full of defects. It hurts fingers and scratches clothes when used. In recent years, someone invented the metal "die-casting method", which can complete the design model in one go. Compared with the old manual work and the rough and clumsy single product, it has indeed made great progress and improvement. It saves time and labor, and can complete mass production with one mold. But it still has certain limitations. Naturally formed jade products do not have uniform specifications and sizes, and it is far from enough to rely on one mold for wrapping and inlaying. Legend has it that the reason why humans invented inlay was the tube setting method. A long time ago, people could only appreciate the precious jade but not wear it. Later, holes were drilled in the blocks. It can only be used as an ornament when strung together with metal or silk threads. Although there was a pendant, there were no other styles, so people cut a circle of tube wall on the hollow metal sleeve to reinforce the gem. This way the gemstone can be seen from both sides. After another set of tube walls are welded on, a ring foot is formed, and the gemstone can be worn on the finger. Through continuous improvement and advancement, a specialized inlay technology was finally developed. Through long-term craft practice, people have summed up a complete set of inlay craft procedures. It is still advanced and widely applicable today.

Claw setting is also called claw setting. Claws refer to the small fine teeth welded on the ring setting. The fine teeth can also be pulled out from the ring setting. The claws can be used to press tightly against the edge of the stone, so it is called claw setting. It is generally divided into four claws, six claws, and double eight claws. No matter which claw setting method is used, the gemstone must be centered, neither biased nor wrinkled. The thickness and height of the claws should be coordinated and moderate. This is a relatively simple inlay method.
The nail setting method is also called the hard setting method. The nail setting method is a new creation in modern times. The nail is shaped like a claw, and it is a small flat-topped "nail" that can press down the edge of the gemstone from the ring setting. The nail rivets the gemstone, and the nail cannot be welded on separately. When using the nail setting method, you must pay attention to the fact that the gemstone cannot be made too deep or too shallow, and it must be coordinated and symmetrical with the ring setting. There are three types of nail setting methods: four-nail setting, diagonal nail setting and dense nail setting.

The forced setting method, also known as the groove setting method, is a relatively new setting method in modern times. There are no claws, and the gems are set tightly together. The metal claws are completely invisible, just like they are sewn together with thread, and the gems are set one by one along the gap. The basic method is to drill straight and parallel small grooves on the ring setting, and the gems are set in the grooves. After careful hammering and filing, the gems are made tight and stable and will never fall off. This setting is best suited for bar or rectangular gemstones.

The tube setting method is also called jump well setting, edge setting, and groove pit setting. It is basically similar to the forced setting method, with only minor differences. It is mostly used for round, oval and egg-shaped gemstones. The grooves drilled only need to be consistent with the circular edge of the gemstone and do not need to be parallel.

There is also a method of "wire inlaying" in the inlay process, which originated from Hengdustan in India. The production skills are relatively high and the difficulty is great. That is, a small deep groove with a narrow mouth and a wide bottom is opened on the finished product with cracks, and round gold or silver wire strips are pressed into the groove to serve as a connection and decoration, which is both beautiful and practical. Commonly known as gold inlaid with jade. It has become rare in the market in recent years. This method is used to repair damaged old ornaments, bracelets, and utensils. Generally, wire pressing is not performed on new finished products, and the production of "mark jade" has gradually faded.
