What Can Go Wrong With Jewelry Quality — And How We Prevent It
Material Control System — The Foundation Of Jewelry Quality
Not all stainless steel or titanium performs the same. Material selection defines long-term durability and skin safety.
We define and control raw materials at engineering level, not just by name.
All stainless steel used in our production is based on 316L grade, known for its low carbon content and corrosion resistance. For titanium collections, we use Grade 2 or Grade 5 titanium, depending on strength and application requirements.
To prevent common market issues such as skin irritation, we control alloy composition and avoid unstable recycled materials that may contain excessive nickel or unknown impurities.
Each incoming material batch is checked for:
• composition consistency
• surface condition
• suitability for plating or polishing
Result: stable base material for coating, skin contact, and long-term wear.
urface & Anti-Tarnish Engineering — Built For Real-World Wear
Our anti-tarnish performance is engineered through a controlled multi-step surface treatment and coating system, designed to withstand real wearing conditions — including sweat, water exposure, and daily friction.
Before coating, each piece undergoes strict surface preparation:
• precision polishing to eliminate micro-scratches and surface defects
• ultrasonic cleaning to remove oil, dust, and residues
• surface activation treatment to enhance coating adhesion
Coating System Control
We apply different coating solutions based on positioning and durability requirements:
• Mid-range gold plating: 0.04–0.05μm
• High-end gold plating: 0.08–0.10μm
• PVD coating (for extended durability applications)
Compared to conventional electroplating, PVD creates a denser and more wear-resistant layer, significantly improving long-term performance.
Resistance To Real-Life Conditions
Our coating system is designed to resist:
• daily friction and wear
• sweat exposure (acidic conditions)
• water and humidity exposure
• oxidation over time
Additional surface treatments are applied where required:
• anti-fingerprint coating to maintain clean appearance
• anti-scratch finishing to reduce visible wear marks
Validation & Testing
To ensure stability, selected products undergo environmental simulation tests:
• Salt spray test: 48–72 hours (corrosion resistance validation)
• Artificial sweat test: simulating prolonged skin contact
• Seawater exposure simulation: for coastal and humid markets
These tests are designed to replicate real-life usage rather than ideal laboratory conditions.
Production Consistency System — No Gap Between Sample And Bulk
We operate a batch-based production control system to ensure repeatability across orders.
Each order is managed with:
• material batch identification
• plating batch tracking
• polishing standard alignment
• process parameter control
Once a sample is approved, its specifications are locked into our production system to ensure all future orders follow the same parameters.
Result: consistent color, finish, and quality across all units and repeat orders.
Inspection & Risk Control — Quality Is Measured, Not Claimed
Our inspection process follows defined standards rather than subjective judgment.
We implement multi-stage inspection including:
• in-process inspection during production
• final inspection before packaging
• visual and functional checks
Defects are classified into:
• critical defects (affect safety or usability)
• major defects (affect appearance or function)
• minor defects
We apply sampling logic based on order size and product type to ensure inspection efficiency and coverage.
In case of non-conformance, we conduct:
• root cause analysis
• corrective action
• rework or replacement if necessary
Result: controlled defect rate and predictable quality performance.
Risk Control & After-Sales — Defined Process With Commercial Accountability
Before shipment, each order is checked against approved samples and specifications, including color consistency, surface condition, functional parts, and packaging integrity to minimize defects before delivery.
If any quality issue is reported after delivery, we require batch reference and visual evidence (photos or videos) to determine whether the issue is related to material, coating, or handling.
Confirmed issues are classified into
Based on the classification and root cause, we apply corresponding solutions
For repeat or batch-related issues, we review production records (material batch, plating batch, process parameters) and implement corrective actions to prevent recurrence in future orders.
We do not apply one fixed solution to all cases — each issue is handled based on its actual impact and cause.
Result: clear responsibility, defined resolution methods, and predictable after-sales support for your business.
