Quality Assurance

At Fyn & Good, we don’t just create beautiful jewelry — we engineer certified, lab-tested stainless steel jewelry that delivers on durability, skin-safety, and everyday luxury. With over 20 years of experience in fine jewelry craftsmanship, our mission is to bring you timeless elegance without compromise.

Every piece we offer is backed by science, certification, and care — because you deserve jewelry that’s as strong and reliable as it is stylish.


🧪 Lab-Tested. Dermatologist Approved. Built to Endure.

We go beyond standard quality control. Our stainless steel jewelry is tested using advanced German precision equipment, ensuring gold plating durability, scratch resistance, and color retention that lasts.

✅ Comprehensive Jewelry Testing — What Makes Our Jewelry So Reliable:

1. Neutral Salt Spray Test (Anti-Corrosion Certified)

Jewelry is exposed to a 5% sodium chloride mist for up to 72 hours to simulate sweat, saltwater, and humidity. The result? Waterproof stainless steel jewelry that won’t rust, fade, or tarnish — even with daily use.

 

 

2. Tumble Abrasion Test

Our plating survives over 5 hours of simulated mechanical damage — validating its strength through repeated free-fall drops. This is how we promise impact-resistant and long-lasting gold-plated jewelry.

3. Localized Friction Test

We simulate daily friction for 4 hours to guarantee your jewelry won't scratch, dull, or wear out, even with repeated contact against skin or fabric.

4. Plating Hardness Test

We test surface durability using a 4H hardness pencil — a rigorous method proving our gold plating resists abrasion better than most traditional finishes.

5. Plating Color Assessment Cabinet

Our jewelry is assessed under varied lighting conditions using international color-matching standards, ensuring consistent gold tone and brilliance in any setting — from day to night.

6. Plating Thickness Test

Using cutting-edge German equipment, we measure gold coating to meet a ≥3μm thickness standard, delivering luxurious shine and protection that lasts over 5 years.
