Quality Check: Our Commitment to Excellence
At UNIHLC, we believe that jewelry should be as enduring as the memories it creates. That’s why every piece in our anti-tarnish collection undergoes a meticulous quality control process to ensure you receive nothing but the best.
Our 4-Step Quality Assurance Process
1. Material Verification
We use premium-grade materials including stainless steel, sterling silver, and gold plating treated with anti-tarnish coatings. Each batch is tested for metal purity, skin safety, and long-lasting shine.
2. Anti-Tarnish Coating Inspection
Our proprietary anti-tarnish technology is lab-tested for durability. We simulate months of wear through accelerated aging tests to ensure your jewelry resists oxidation, discoloration, and fading.
3. Craftsmanship Review
Every item is carefully inspected by hand for design accuracy, smooth finishes, secure clasps, and stone settings. From delicate chains to statement rings, we ensure a flawless finish in every detail.
4. Wear-Test Protocols
Select pieces are wear-tested by our team under real-life conditions to monitor comfort, durability, and tarnish resistance. Only after passing these tests does a piece earn our signature seal of quality.
