Description

Technical Field

[0001] This invention relates to the field of jewelry manufacturing and gemstone processing technology, and in particular to a method and system for achieving full-process traceability and accurate cost inheritance for high-value gemstones during cutting, polishing and other processing. Background Technology

[0002] In the processing of precious gemstones (such as diamonds, emeralds, and rubies), each rough stone possesses unique characteristics and a high value. Traditional processing cost accounting typically uses the batch average method, distributing the total cost of a batch of rough stones evenly across all finished products produced in that batch. This method has a serious flaw:

[0003] 1. Inability to trace the origin of a single gemstone: It is impossible to confirm the exact source of the original rough stone of a finished gemstone. This is crucial for precious stones with collection, certification and inheritance significance, and it loses the "story" and uniqueness of the product.

[0004] 2. Severe distortion in cost accounting: The cost of a finished product produced from a high-quality, high-priced raw material should be much higher than that of a similar finished product produced from an ordinary raw material. However, the average rule completely obscures this value difference, causing cost information to fail to reflect the true value flow and affecting pricing and profit analysis.

[0005] 3. Vague processing performance and loss management: When processing losses are abnormal, it is impossible to accurately pinpoint whether the problem lies with a specific rough stone or a particular processing operation, which is not conducive to process improvement and responsibility determination.

[0006] Therefore, the jewelry industry urgently needs a technological solution that can tightly bind the identity of a single rough gemstone to all the finished gemstones produced after processing, and achieve accurate cost transmission and traceability. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method and system for traceability and accurate cost calculation applicable to the processing of precious gemstones. This method creates a unique identifier for each rough stone and accurately allocates its cost among the finished products produced, thereby achieving full life-cycle management and financial-grade cost accounting from rough stone to finished product.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A method for accurately calculating the cost of valuable stone materials based on material traceability, characterized by the following steps:

[0010] S1: Initialize the original stone's identity

[0011] 1. Assign a globally unique rough gemstone identification code to each individual or batch of indistinguishable precious gemstone rough, serving as the rough stone's "digital ID card".

[0012] 2. Record the initial total cost of the raw stone, which includes the purchase price, customs duties and other related direct costs.

[0013] 3. Establish and store a strong binding relationship between the raw stone identification code and the initial total cost in the system backend.

[0014] S2: Processing and Outbound Traceability

[0015] 1. When the raw stone is sent out for cutting, polishing, or other processing, its raw stone identification code is specified by scanning or selection during the outbound operation.

[0016] 2. Based on the identification code, the system automatically associates and retrieves the corresponding initial total cost, and locks this cost as the benchmark for this processing calculation.

[0017] S3: Finished Goods Receiving and Cost Allocation

[0018] 1. When the finished gemstones (which may be one or more) are returned to the warehouse after processing, the original stone identification code inherited by them shall be indicated in the warehousing operation.

[0019] 2. The system is then linked back to the corresponding initial total cost.

[0020] 3. Enter the total weight of all finished gemstones produced after this processing (usually in carats).

[0021] 4. System execution cost allocation calculation:

[0022] 1. Calculate the unit weight cost: Unit cost = Initial total cost / Total weight of finished products.

[0023] 2. Calculate the cost per unit: Cost per unit = Unit cost × Weight of the unit.

[0024] S4: Source Information Inheritance and Display

[0025] 1. The system assigns the rough stone identification code as a traceability label to each finished gemstone produced in this processing.

[0026] 2. The inventory information for finished gemstones records and displays the inherited rough stone identification code. Users can trace the origin and cost information of the original rough stone by querying this identification code.

[0027] Preferably, the method further includes a step S5: verification and error prevention mechanism.

[0028] 1. During the operation confirmation in step S2 or S3, the system verifies whether the currently referenced initial total cost is consistent with the latest bound cost in the database. If they are inconsistent, a warning is issued and the operation is interrupted to prevent accidental or malicious data tampering and to ensure the authority and consistency of cost data.

[0029] The present invention also provides a system for implementing the above method, characterized in that it comprises:

[0030] 1. Identification Management Module: Used to create and manage raw stone identification codes and their binding relationship with the initial total cost.

[0031] 2. Processing Operation Module: This module is used to perform processing outbound and finished product inbound operations, and integrates cost allocation calculation logic.

[0032] 3. Traceability Data Module: Used to store and maintain the traceability chain between raw stones and finished products.

[0033] 4. Verification and Alarm Module: Used to perform cost consistency verification and issue alarms when an anomaly occurs.

[0034] Beneficial effects of the present invention

[0035] 1. Achieve precise traceability at the single-stone level: Establish a complete "bloodline" inheritance from a single rough stone to a single (or multiple) finished product, which greatly enhances the added value of precious stones and customer trust.

[0036] 2. Financial-grade precision in cost accounting: Cost calculation is accurate to the cost per carat of each finished gemstone, truly reflecting its value source and providing a reliable basis for accurate pricing, profit analysis, and corporate asset valuation.

[0037] 3. Improve management efficiency: By tracking the processing output rate (total weight of finished products / weight of raw stone) under the same raw stone, the processing technology level and loss situation can be clearly assessed, and refined production management can be achieved.

[0038] 4. Data security and reliability: Through error prevention mechanisms such as cost consistency verification, the accuracy and security of core cost data are effectively guaranteed during the transfer process, avoiding the risks caused by human error or tampering. Attached Figure Description

[0043] The preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings to fully illustrate the implementation and working principle of the invention. This embodiment takes the processing of a rough diamond as an example.

[0044] Environmental preparation for implementation:

[0045] The method described in this invention is implemented through an integrated jewelry production management system. This system is deployed on a server, and users operate it through a browser or application on a client device (such as a computer or tablet).

[0046] Specific implementation steps:

[0047] 1. Initialize the original gem's identity (corresponding to...) Figure 1 S1 steps and Figure 2 (Identification Management Module)

[0048] Operation: The purchasing staff put a 5.2-carat rough diamond (purchase price 50,000 yuan) into the warehouse.

[0049] System execution: In the system's "Original Stone Management" interface, click "Add". The system will automatically generate a unique original stone identifier code, such as DIA-2024-001A.

[0050] Operation: The purchasing staff enters the initial total cost of 50,000 yuan.

[0051] System execution: The system backend creates an immutable record in the database: {Original Stone Identifier: "DIA-2024-001A", Initial Total Cost: 50000, Status: "In Stock"}.

[0052] 2. Processing and outbound traceability (corresponding to...) Figure 1 S2 steps Figure 2 Processing operation module and Figure 3 interface)

[0053] Procedure: The processing technician needs to collect the raw stone for cutting. On the system's "Processing Outbound" interface, scan the barcode DIA-2024-001A using a barcode scanner.

[0054] System execution (see) Figure 3 ):

[0055] The "Raw Stone Identification Code" field on the interface is automatically filled with DIA-2024-001A.

[0056] The system immediately queries the database and automatically fills in the "Initial Total Cost" field with the bound 50,000 yuan.

[0057] This field is read-only to prevent accidental modification.

[0058] Operation: After the operator confirms other information (such as processing type), click "Confirm Outbound".

[0059] System execution (verification mechanism): Upon clicking "Confirm," the system re-verifies whether the current cost value of 50,000 matches the value in the database. If they match, the process passes, and the raw stone's status is updated to "Processing"; if they do not match, a warning pops up, preventing the stone from leaving the warehouse.

[0060] 3. Finished product warehousing and cost allocation (corresponding to...) Figure 1 S3 step)

[0061] Background: After the rough diamond was cut and polished, a batch of finished diamonds was produced, including a 2.1-carat top-quality diamond with D color and IF clarity (which can be used as the main stone in the future), and three smaller high-quality diamonds (which can be used as side stones in the future, with sizes of 0.5ct, 0.4ct, and 0.3ct respectively).

[0062] Operation: After processing is completed, on the "Finished Product Drilling Warehouse" interface, the operator selects the inherited "Rough Stone ID" DIA-2024-001A.

[0063] System execution:

[0064] The system automatically populates the "Initial Total Cost" of 50,000 yuan.

[0065] The operator enters the total weight of all finished diamonds produced this time: 2.1 + 0.5 + 0.4 + 0.3 = 3.3 carats.

[0066] The system automatically calculates the "cost per unit weight": 50,000 / 3.3 ≈ 15,151.52 yuan / carat.

[0067] The system automatically calculates the cost of each finished diamond:

[0068] Finished diamond-01 (2.1ct): 15,151.52 * 2.1 ≈ 31,818.19 yuan

[0069] Finished diamond-02 (0.5ct): 15,151.52 * 0.5 ≈ 7,575.76 yuan

[0070] Finished drill bit-03 (0.4ct): 15,151.52 * 0.4 ≈ 6,060.61 yuan

[0071] Finished diamond-04 (0.3ct): 15,151.52 * 0.3 ≈ 4,545.45 yuan

[0072] 4. Inheritance and display of traceability information (corresponding to) Figure 1 S4 step)

[0073] System execution: The system assigns the rough stone ID DIA-2024-001A to these four finished diamonds respectively.

[0074] Operation: Users can check the "Finished Diamond Inventory".

[0075] System execution: In the list, each finished diamond displays its "rough stone ID" as DIA-2024-001A. Hovering over it displays cost details.

[0076] Summary of Implementation Examples:

[0077] Through the above implementation process, this invention successfully and accurately allocated the cost of a rough diamond (DIA-2024-001A) worth 50,000 yuan to the four finished gemstones produced after its processing, and gave them a unified and traceable "digital ID card". The entire process is data-driven, automatically calculated, and protected by a verification mechanism, perfectly realizing refined and traceable management of high-value gemstone processing.
