Description

Technical Field

[0001] This utility model belongs to the field of jewelry technology, specifically the structure of jade, gemstone and gold and silver inlaid ornaments. Background Technology

[0002] Gold and silver inlay is a traditional Chinese decorative technique for metalware, first appearing on bronze artifacts from the Shang and Zhou dynasties. The process involves first drawing the desired pattern on the bronze surface, then chiseling dovetail grooves according to the pattern. Gold or silver is then drawn into fine wires or hammered into thin sheets and embedded into the grooves. Finally, it is hammered in place, polished, and the surface is smoothed. The gold and silver patterns create a striking contrast with the bronze body, enhancing the bronzeware's elegance and brilliance.

[0003] During the Han Dynasty, another technique for inlaying gold and silver onto bronze vessels emerged—the gilding method, also known as the plating method. This involved dissolving gold and silver in mercury to create gold or silver paste, which was then applied to grooves chiseled into the surface of the bronze vessel. The mercury was then evaporated by heating over charcoal, and finally, the surface was polished smooth. Compared to the inlay method used during the Shang and Zhou dynasties, the gilding method significantly improved efficiency and allowed for the creation of more complex and intricate patterns.

[0004] The gold and silver inlay technique for jade and gemstone ornaments was extremely popular during the Qianlong period of the Qing Dynasty. The materials used included Hetian jade, jadeite and other jade stones, agate and other gemstones. These materials are much harder than bronze, which makes the gold and silver inlay technique more demanding. The lines of the patterns must be smooth and the grooves of the carving must be of uniform thickness. Otherwise, it is difficult to embed the gold and silver wires, and even if they are embedded, the bonding force will not be strong, making the construction extremely difficult.

[0005] Currently, the gold and silver inlay technique for jade and gemstones still uses traditional inlay or gilding methods, but the tools and equipment used have been greatly improved. Laser engraving has replaced traditional hand carving, allowing for more complex, intricate, and uniform inlay grooves. Under a microscope, the fine patterns made the jade details more vivid and perfect. However, these delicate operations demand extremely high skill from the craftsmen. Often, a single piece may require an experienced craftsman to spend weeks or even months on it, especially for thin-walled jade and gemstone jewelry where gold and silver inlay is even more difficult. A mistake during the process can ruin the entire piece. While gilding reduces the difficulty of the process, it also has significant drawbacks. The gilding process uses mercury, and long-term exposure to mercury can seriously harm the health of the workers. There is also a risk of mercury residue remaining on the surface of the jade and gemstones, affecting the wearer's health. Furthermore, the temperature required to remove the mercury is close to 400℃, which can cause significant damage to the jade and gemstone materials. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides the following technical solution: a structure for jade, gemstone, and gold and silver inlaid ornaments, comprising a seed layer, a conductive layer, and an electroforming layer.

[0007] Preferably, the seed layer is made of one of the metal or alloy particles such as silver, palladium, gold, or titanium, and is evenly covered in the grooves and surrounding areas of the jade or gemstone that have been pre-cut.

[0008] Preferably, the metal or alloy particles such as silver, palladium, gold, and titanium selected for the seed layer can be obtained through non-metallic chemical plating, vacuum ion plating, or magnetron sputtering.

[0009] Preferably, the conductive layer can be one or a combination of two metal layers selected from copper, nickel, silver or gold. When gold is inlaid, the conductive layer is preferably a pure gold layer, and when silver is inlaid, the conductive layer is preferably a pure silver layer. The thickness of the gold or silver conductive layer is not less than 0.1 micrometers.

[0010] Preferably, the pure gold conductive layer and the pure silver conductive layer can be achieved by electroplating, vacuum ion plating or magnetron sputtering.

[0011] Preferably, when gold is inlaid, the electroformed layer is formed by electroforming in a pure gold plating bath, and when silver is inlaid, the electroformed layer is formed by electroforming in a pure silver plating bath. The Vickers hardness of the electroformed gold or silver layer does not exceed 130 HV.

[0012] Preferably, the thickness of the electroplated gold or silver layer should exceed the maximum depth of the inlaid gold and silver grooves. Electroplated gold and silver layers that exceed the height of the jade or gemstone surface should be filed or ground flat using a high-hardness carbon steel file.

[0024] Example 1:

[0025] In this embodiment, a Hetian jade pendant with a black background is used for gold inlay. The pattern is a galloping horse. Grooves are carved using laser engraving, with a depth of approximately 200 micrometers. A uniform 31 palladium seed layer is deposited in and around the grooves of the galloping horse using a non-metallic chemical plating process. The 32 conductive layer in this embodiment uses a combination of nickel and gold plating. First, the 34 Hetian jade pendant with the 31 palladium seed layer is immediately immersed in a nickel plating solution to deposit a nickel conductive layer approximately 1 micrometer thick. Then, a pure gold conductive layer of at least 0.1 micrometers is deposited in an acid gold plating solution. Finally, a 33 pure gold electroforming layer of at least 220 micrometers thick is electroformed in a cyanide-free electroforming gold solution. Excess gold layer exceeding the 34 Hetian jade surface is manually filed down with a high-hardness carbon steel file, and the finished product is obtained after polishing. The average Vickers hardness of the 33 pure gold electroforming layer is tested to be 102 HV.

[0026] Example 2:

[0027] In this embodiment, a black jade pendant with a galloping horse design was selected for the silver inlay process. Grooves were laser-engraved to a depth of approximately 220 micrometers. A uniform 41 silver seed layer was deposited within and around the grooves of the galloping horse using a non-metallic chemical plating process. The 44 black jade pendant with the deposited silver seed layer was immediately immersed in a chemical silver plating solution to deposit a 42 silver conductive layer approximately 2 micrometers thick. Then, a 43 pure silver electroforming layer with a thickness of at least 250 micrometers was electroformed in a cyanide-free electroforming silver bath. Excess silver layer exceeding the surface of the 44 black jade pendant was manually filed down with a high-hardness carbon steel file, and the finished product was obtained after polishing. The average Vickers hardness of the 43 pure silver electroforming layer was tested to be 85 HV.
