- Incoming Material Inspection: Random sampling of all metal/stone components.
- Initial Production Inspection: Confirmation of the first piece from each batch.
- In-Process Inspection: 100% self-inspection by dedicated personnel at critical stages (e.g., hand-setting) to ensure no risk of gemstone detachment.
- Final Product Inspection: Comprehensive checks on functionality, appearance, plating adhesion, and gemstone security.
- Pre-shipment Sampling: An independent QC team of 8-12 inspectors enforces AQL standards, strictly controlling defect rates below 1%.
