Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0026] In order to reduce the cost of production, this application no longer uses the traditional method of inlaying diamonds or gemstones to enhance the light and shadow effects of jewelry. Instead, it considers performing special processing on the surface of the precious metal matrix itself so that it can present good light and shadow effects under light, thereby ensuring the beauty of the jewelry.

[0027] Based on this, after research and practice, the present application processes several reflective parts on the surface of the precious metal substrate, and the reflective parts include multiple circles of circular grooves, so as to utilize the surface of the circular grooves to reflect light in different directions, so that the surface of the jewelry made of the precious metal substrate presents a good light and shadow effect. Moreover, this method does not require diamonds or gems to be inlaid on the precious metal substrate, which can effectively save the processing and manufacturing costs of jewelry and enhance product competitiveness.

[0028] According to one aspect of the embodiment of the present application, there is provided a piece of jewelry, see Figure 1 and Figure 2 , Figure 1 The front structure of the jewelry provided by the embodiment of the present application is shown in FIG. Figure 2 Shown in Figure 1 As shown in the cross-sectional structure along line AA, the jewelry 100 includes a precious metal base 110, at least one surface of which is provided with a plurality of reflective portions 111. The reflective portions 111 include multiple annular grooves 112. The multiple annular grooves 112 in each reflective portion 111 are concentrically arranged, i.e., the multiple annular grooves 112 form concentric circles.

[0029] The precious metal substrate 110 can be gold, platinum, silver, etc. Figure 1 and Figure 2 The circular sheet structure shown in the figure may also be a circular column, a square sheet, a square block, a circular ring, etc. The specific shape can be set accordingly according to the jewelry type or other needs, and is not limited here.

[0030] The reflective portion 111 refers to a collection of multiple concentric annular grooves 112 . The surfaces of these annular grooves 112 can reflect light, so that the surface of the noble metal substrate 110 presents a good light and shadow effect.

[0031] In order to better understand and demonstrate the actual structure of the reflective portion 111, please refer to Figures 3 to 5 The electron microscope image of the noble metal substrate 110 shows that each reflective portion 111 has multiple concentric annular grooves 112 .

[0032] For specific lighting effects, please refer to Figures 6 to 9 The figures show the light and shadow effects of precious metal substrates 110 of different shapes under the illumination of a surface light source. Due to the presence of the annular groove 112 in the reflective portion 111, the surface of the precious metal substrate 110 is uneven, and the surface orientation of each position of each annular groove 112 is different. These factors make the surface of the precious metal substrate 110 present a light and shadow effect of alternating light and dark under the illumination of sunlight or a surface light source, and the jewelry 100 as a whole presents a three-dimensional light and shadow effect with good aesthetics.

[0033] Jewelry 100 can be Figure 6 or Figure 7 The pendant shown in the Figure 8 or Figure 9 The ring shown in FIG. , of course, in some other embodiments, the jewelry 100 can also be a bracelet, a bangle, a necklace, an earring, etc., which is not specifically limited here.

[0034] Please refer to Figures 10 to 12 ,in Figure 10 and Figure 11 The figure shows the light and shadow effects of precious metal substrates 110 of different shapes under an electron microscope under the illumination of a yellow point light source. Figure 12 The figure shows the light and shadow effects of a real-life precious metal substrate 110 under a standard lens. As shown in the figure, due to the uneven surface of precious metal substrate 110 and the different surface orientations of each annular groove 112, when illuminated by a point light source, the surface of precious metal substrate 110 appears brightly lit at locations where the light from the point light source's optical axis is more intense. The remaining locations appear as long, fan-shaped light spots radiating outward from the bright spot. These fan-shaped light spots gradually darken and taper from locations closer to the bright spot to those further away. This light and shadow effect creates a visually appealing effect on the surface of jewelry 100, as if light were concentrated inward from all four sides, centered around the bright spot.

[0035] In addition, Figure 10 For example, in Figure 10Based on the state shown, when the relative position between the precious metal substrate 110 and the point light source is continuously adjusted and the precious metal substrate 110 is observed synchronously, the position of the bright light spot on the precious metal substrate 110 will also change accordingly, presenting a "chasing light" effect, that is, the bright light spot will chase the light source, thereby making the jewelry 100 present a good dynamic light and shadow effect.

[0036] In order to make the light and shadow effect extend all the way to the edge of the precious metal substrate 110, as shown in FIG. Figure 1 and Figure 6-Figure 9 As shown, the annular grooves 112 in the reflective portion 111 in the middle area of the surface of the precious metal substrate 110 are all complete annular, while the annular grooves 112 in the reflective portion 111 in the edge area of the surface of the precious metal substrate 110 are at least partially arc-shaped, that is, not all grooves in the reflective portion 111 in the edge area are a complete circle of annular grooves 112, but some of the grooves or all of the grooves do not form a complete circle. Figure 1 The portion that does not form a complete circle is marked as an arc-shaped groove 113. The purpose of this arrangement is mainly to enable the reflective portion 111 to cover the edge position of the surface of the precious metal substrate 110 to ensure that the edge position can also present the corresponding light and shadow effect.

[0037] Furthermore, in order to make the light and dark on the surface of the jewelry 100 dense and regular, the light and shadow effect is better, such as Figures 3 to 5 as well as Figure 13 As shown in , the edges of all two adjacent reflective portions 111 are adjacent to each other. Specifically, several reflective portions 111 fill at least one entire surface of the noble metal substrate 110 .

[0038] Specifically, if the reflective portion 111 in the middle area only includes multiple complete circular grooves 112, then there will inevitably be a certain gap between the outermost circular grooves 112 in different reflective portions 111, which makes it impossible for several reflective portions 111 to cover the entire surface of the precious metal substrate 110.

[0039] Based on this, in addition to the annular groove 112 or arc-shaped groove 113, the outermost position of the reflective portion 111 also includes some smaller connecting grooves 114, which can be arc-shaped or strip-shaped. Adjacent reflective portions 111 are connected to each other through the outermost annular groove 112 or arc-shaped groove 113 and the connecting grooves 114 on the peripheral edge, so that several reflective portions 111 fill the entire surface of the precious metal substrate 110. After filling, as Figures 10 to 12 As shown, the light and shadow effects on the surface of the precious metal substrate 110 are regularly distributed with alternating light and dark, the brightness changes evenly, and the overall light and shadow effects are good.

[0040] like Figure 2As shown in , the side of the noble metal substrate 110 provided with the reflective portion 111 may be a concave surface, which has a better light-collecting effect and can make the light and shadow effect on the surface of the noble metal substrate 110 more intense. Of course, in some other embodiments, the side of the noble metal substrate 110 provided with the reflective portion 111 may also be a flat surface.

[0041] Similarly, if Figure 2 As shown in , the multiple ring-shaped grooves 112 in each reflective portion 111 can be recessed inward from the outer circle to the inner circle. This allows each reflective portion 111 to have a certain light-gathering effect as a whole. Furthermore, the surface contrast between light and dark in the multiple ring-shaped grooves 112 in each reflective portion 111 is more intense, and the light and shadow effects on the surface of the precious metal substrate 110 are more obvious. Of course, in other embodiments, the multiple ring-shaped grooves 112 in each reflective portion 111 can also be distributed in a planar state as a whole.

[0042] Considering that after long-term wearing, if the reflective portion 111 on the surface of the precious metal base 110 is worn, the light and shadow effect may be weakened, thereby affecting the subsequent aesthetics of the jewelry 100. For this, please refer to Figures 14 to 17 , Figure 14 The front structure of a jewelry 100 provided by another embodiment of the present application is shown. Figures 15 to 17 Schematic diagrams of the structures of jewelry 100 provided in several embodiments of the present application are shown. As shown in the figures, jewelry 100 may further include a frame 120, which surrounds and covers the edge of the precious metal base 110. Frame 120 may be made of the same precious metal material as precious metal base 110, or other metals, alloys, or plastics with greater hardness and wear resistance.

[0043] By surrounding the edge of the precious metal substrate 110 with the frame 120 , the edge of the precious metal substrate 110 can be protected to prevent the edge of the precious metal substrate 110 from being chipped or scratched due to collision or friction.

[0044] In order to further improve the aesthetics, Figure 15 and Figure 16 As shown, a first decorative portion 121 may be provided on the frame 120. The first decorative portion 121 may be Figure 15 The protrusions shown in the specific shape can also be Figure 16 The hollow structure shown can of course also be a plane or three-dimensional pattern, etc., which is not limited here.

[0045] like Figure 17 As shown in , the surface of the noble metal substrate 110 may further be provided with a second decorative portion 122 by welding or the like. The second decorative portion 122 may be a protrusion of a specific shape, a plane or three-dimensional pattern, or the like.

[0046] It can be understood that in the specific implementation process, the first decorative part 121 can be set only on the frame 120, or the second decorative part 122 can be set only on the precious metal substrate 110. Of course, the first decorative part 121 and the second decorative part 122 can also be set on both at the same time, and the decorative parts at different positions can be the same or different.

[0047] According to another aspect of the embodiment of the present application, a jewelry processing method is provided. Figure 18 , the figure shows a flow chart of a jewelry processing method provided by an embodiment of the present application. As shown in the figure, the jewelry processing method includes the following steps: Step 210: Place the precious metal substrate on a fixture of a processing device.

[0048] In this step, the precious metal substrate can be preliminarily formed into a sheet, column, block, ring, etc., and its processing surface can be a flat plane or a smooth curved surface. The processing equipment can be a CNC machine tool.

[0049] Step 230: Control the tool head of the processing equipment to process a plurality of reflective portions arranged in an array on the surface of the precious metal substrate. The reflective portions include multiple circles of annular grooves, and the multiple circles of annular grooves in each reflective portion are concentrically arranged.

[0050] The precious metal substrate 110 with several reflective portions 111 processed in this step is as follows: Figure 1 shown.

[0051] Step 250: Make jewelry.

[0052] In the jewelry manufacturing method provided in the embodiment of the present application, a processing device is used to control the cutter head to process a plurality of reflective portions arranged in an array on the surface of a precious metal substrate, and the reflective portions include multiple ring-shaped grooves. The multiple ring-shaped grooves in each reflective portion are concentrically arranged, so that the surface of the processed jewelry appears as follows when illuminated by a surface light source. Figures 6 to 9 The three-dimensional light and shadow effect shown in the figure is as follows: Figures 10 to 12 The state shown in the figure is similar to the state of focusing light inward from all sides with a bright light spot as the center. Without the need to inlay gems or diamonds to reduce manufacturing costs, it can create a beautiful light and shadow effect on the surface of the jewelry.

[0053] The above step 230 may specifically include the following steps: Step 231: The processing equipment controls the tool head to move to a plurality of preset coordinates in sequence, and after each movement of the tool head to the preset coordinates, the tool head is first controlled to descend and rotate synchronously, and then the tool head is controlled to ascend and reset, so as to process a plurality of reflective portions arranged in an array on the surface of the precious metal substrate.

[0054] Among them, Figure 19 As shown in FIG, the blade 310 of the cutter head 300 is in an arc-shaped sawtooth shape, which makes the reflective portion 111 formed by the cutter head through rotation as shown in FIG. Figure 1 and Figure 2 As shown, the tool head 300 includes multiple concentric, circular grooves 112 that are each concave toward the center. Specifically, the tool head 300 may be made of black polycrystalline diamond (PCD), a superhard material formed by sintering diamond powder under high temperature and high pressure. PCD is capable of effectively cutting precious metal substrates. Furthermore, the tool head 300 utilizes black polycrystalline diamond with a surface roughness greater than or equal to 1 μm and a particle size greater than or equal to 50 μm. This parameter range enables the blade 310 to effectively form a serrated shape, enabling machining of the circular groove 112.

[0055] Each preset coordinate is the coordinate where the rotation point of blade 310 (the intersection of the rotation axis and blade 310) is relative to the center point of each reflective portion (i.e., the center of the circular groove in the reflective portion). The specific processing flow is as follows: the processing equipment first controls its cutting head to move to the first preset coordinate, then lowers and rotates synchronously to machine the first reflective portion on the surface of the precious metal substrate. The cutting head 300 then rises and resets, moves to the next preset coordinate, lowers again, and rotates synchronously to machine the next reflective portion, and so on, until all preset coordinates have been traversed, that is, until all reflective portions have been machined.

[0056] By using a cutting head 300 with a serrated blade 310 and performing processing by rotating the cutting head, the concentricity of the multiple circular grooves in the several reflective parts can be effectively guaranteed, thereby ensuring the regularity of the light and dark distribution and brightness changes in the light and shadow effects presented by the processed precious metal substrate through the several reflective parts.

[0057] It should be noted that when rotating the cutter head to form annular grooves, to ensure that the annular groove is formed throughout the entire processing area and to maintain the desired light and shadow effects, it is considered to set the feed distance of the cutter head 300 to be larger, so that the entire blade can fully contact and cut the precious metal substrate, thereby producing multiple closely spaced annular grooves. However, in practice, it has been found that when the feed distance of the cutter head 300 is too large, the inner ring is blocked by the outer ring, resulting in chip removal and heat dissipation difficulties, which in turn leads to problems such as chip blockage and cutter head overheating, affecting processing accuracy and success rate.

[0058] In this regard, the present application considers adopting a method of cutting multiple times and gradually increasing the feeding distance to overcome the above problem. Specifically, the above step 231 is repeated multiple times, and the feeding distance of the cutter head 300 is gradually increased.

[0059] Assuming the cutting depth is 3mm and the feed rate each time is 0.2mm more than the previous one, the specific process is as follows: First, control the cutter head 300 to move to the first preset coordinate, then control the cutter head 300 to descend and rotate synchronously. After the cutter head 300 descends to the first height in contact with the surface of the precious metal substrate, it continues to descend by 0.2 mm (this is the feed distance for the first processing) to preliminarily process the first reflective part. Then the cutter head 300 rises, resets and moves to the next preset coordinate. The cutter head 300 descends again and rotates synchronously. After contacting the surface of the precious metal substrate, it continues to descend by 0.2 mm to preliminarily process the next reflective part, and so on, until all the reflective parts are preliminarily processed.

[0060] Then control the cutter head 300 to move to the first preset coordinate, and then control the cutter head 300 to descend and rotate synchronously. After the cutter head 300 descends to the above-mentioned first height, it continues to descend 0.2mm+0.2mm=0.4mm (this is the feed distance for the second processing) to perform secondary processing on the first reflective part. Then the cutter head 300 rises and resets and moves to the next preset coordinate. The cutter head 300 descends again and rotates synchronously. After reaching the first height, it continues to descend 0.4mm to perform secondary processing on the next reflective part, and so on, until all reflective parts are processed secondary.

[0061] The steps described in the above two paragraphs are repeated until each reflective portion is processed 15 times and a total cutting depth of 3 mm is reached. Then, the processing is completed to produce the jewelry.

[0062] It is understandable that the above-mentioned specific values of cutting depth, feed rate per time and number of processing times are only exemplary and do not constitute a limitation on the specific values of the corresponding parameters.

[0063] This method of gradually increasing the feed distance can ensure that the depth of each cutting is not too large, thereby preventing problems such as chip removal and heat dissipation difficulties in the inner ring.

[0064] During machining, the linear distance between two adjacent preset coordinates can be set to be equal to the rotational diameter of the cutter head. The two adjacent preset coordinates mentioned here do not refer to being adjacent in terms of control sequence, but rather to being adjacent in a spatial sense. That is, they do not refer to the two preset coordinates reached by the cutter head 300 during two consecutive movements, but rather to two preset coordinates adjacent to each other on the moving plane of the cutter head 300.

[0065] Based on this, the straight-line distance between two adjacent preset coordinates is equal to the rotation diameter of the cutter head 300, which means that among the several reflective parts processed, the outer circles of any two adjacent reflective parts are tangent to each other. Figure 1This arrangement enables the plurality of reflective portions 111 to be evenly and closely arranged on the surface of the noble metal substrate 110 , thereby ensuring the compactness and consistency of the light and shadow effects presented on the surface of the noble metal substrate 110 .

[0066] Of course, the straight-line distance between two adjacent preset coordinates can also be set to be smaller than the rotation diameter of the cutter head 300, which makes the two adjacent reflective parts overlap. Accordingly, in the actual processing process, the reflective part processed later will cut off a part of the reflective part processed earlier, and finally present as follows Figures 3 to 5 as well as Figure 13 In the jewelry processed in this way, the reflective portion 111 includes multiple complete circular grooves 112 in the middle, and there are some arc-shaped connecting grooves 114 at the edge. The adjacent reflective portions 111 are closely connected through the outermost complete circular grooves 112 and these connecting grooves 114. The entire surface of the precious metal base 110 is filled with the reflective portion 111, thereby making the light and shadow effect on the surface of the precious metal base 110 as shown. Figures 10 to 12 The light and dark shown are distributed regularly, the light changes are even, and the overall light and shadow effect is good.

[0067] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of this application and are not intended to limit them.
