How We Check Stainless Steel Jewelry Quality Before Shipment: The 4Tune Fashion Standard

At 4Tune Fashion, we believe that jewelry is more than just an accessory—it’s an expression of your style and confidence. That’s why we take quality control (QC) incredibly seriously. Before any piece of our stainless steel jewelry makes its way to your doorstep, it undergoes a rigorous multi-step inspection process to ensure you receive only the best.

Here is a look at how we ensure your 4Tune pieces remain tarnish-resistant and durable for years to come:

1. Material & Finish Inspection

Every piece starts with high-grade 304L or 316L stainless steel, known for its strength and hypoallergenic properties. We inspect the surface of every ring, necklace, and earring for any scratches or uneven polishing. Our goal is a mirror-like finish that feels smooth against your skin, a hallmark of high-quality jewelry.

2. PVD Plating Durability Check

We use professional PVD plating (Physical Vapor Deposition) technology, often featuring 18K gold plated finishes. During our jewelry inspection, we check for color consistency across the entire batch. This process ensures the plating is thick and even, so your jewelry remains waterproof and won’t fade during daily wear.

3. Functional & Strength Testing

A beautiful piece must be functional. We manually test every component to ensure durable jewelry standards:

  • Clasps & Closures: We open and close lobster clasps and hinges multiple times to ensure they are secure.
  • Stone Settings: For pieces with crystals, we verify that all stone settings are firm and won’t budge.
  • Link Strength: We perform a “tug test” on chains to ensure all jump rings are perfectly closed.

4. Ultrasonic Cleaning & Final Polish

Before packaging, every item goes through ultrasonic cleaning to remove any microscopic dust or residue. We then give it a final hand-buff with a microfiber cloth to ensure it sparkles the moment you open your jewelry packaging.

5. The Final “Green Light”

Only after a piece passes all these steps does it get the 4Tune Fashion seal of approval. When you shop at www.4tunefashion.com, you’re not just buying an accessory; you’re investing in professional jewelry craftsmanship.
