Quality Control Process Overview

In our rigorous quality management system, the quality control (QC) process is integrated throughout the entire production cycle to ensure that every piece of jewelry meets high-quality standards and complies with the stringent requirements of high-end brands in Europe, the US, and other regions. Our QC process mainly consists of the following key steps:

1. **Raw Material Inspection**
All raw materials used in jewelry production are thoroughly inspected before entering the manufacturing process. We ensure that the precious metals, gemstones, and other materials meet international quality standards, as well as environmental and safety requirements. Each batch of raw materials undergoes component analysis and visual inspection to ensure purity, color, gloss, hardness, and other key attributes are in line with our strict standards.

2. **Sampling During Production**
During production, we perform regular sampling checks to ensure the quality of each production stage. We inspect details at every critical process, including welding, setting, polishing, and other key techniques, identifying and correcting potential issues to maintain precision and consistency throughout the manufacturing process. This ensures that every piece of jewelry is crafted with high attention to detail and quality.

3. **Finished Product Quality Inspection**
After the jewelry is completed, we conduct a comprehensive quality inspection for each item. The inspection covers the following three main areas:
– **Appearance Inspection**: This includes checking for surface smoothness, blemishes (such as scratches, color differences, or air bubbles), the firmness of gemstone settings, and overall craftsmanship.
– **Size Measurement**: We measure the size of each piece of jewelry with precision, ensuring it meets design specifications, including the inner diameter of rings, length of necklaces, weight of earrings, etc. Every detail is checked to ensure accuracy.
– **Functionality Testing**: For jewelry pieces with special functions (e.g., adjustable rings, necklaces with opening/closing mechanisms, etc.), we conduct multiple functionality tests to ensure that all components operate correctly, and the pieces are comfortable and safe to wear.

4. **Inspection Reports and Third-Party Verification**
To ensure transparency and reliability in our quality control, we provide detailed inspection reports, which include the results, data, and compliance with quality standards for all checked items. Should clients require, we also welcome third-party professional agencies to conduct inspections, further ensuring that our products meet international standards.

Through this meticulous quality control process, we not only guarantee the high quality of every piece of jewelry but also provide our clients with trustworthy QC data, ensuring the reputation of the brand and customer satisfaction.
