6-Layer Plating, 4 Quality Tests, 1 Thoughtful Standard

When it comes to demi-fine jewellery, the expectations are clear: pieces should be elegant, durable, and crafted with exceptional skill. But in reality, finding jewellery that truly meets all these standards isn’t always easy.

We meet this expectation at BY TONIN through a process that combines meticulous craftsmanship with close attention to detail. Every piece is thoughtfully designed and carefully made to the highest quality standards.

For us, jewellery is part of your life, a companion through your moments and memories. That’s why we hold ourselves to a principle of transparency and integrity in all we do, ensuring each piece reflects beauty, honesty, care, and respect for both people and planet.

Here’s how we deliver on that promise:

6 Layers of Precision Plating

Unlike many demi-fine pieces that depend on a single plating layer, our jewellery is crafted through an advanced, multi-layer plating system. Each layer is engineered to enhance strength, brilliance, and wear resistance, delivering a performance that sets a new standard in the category.

1. Sterling Silver Base
Every piece begins with a solid foundation of sterling silver — a durable, hypoallergenic metal engineered for comfort and longevity. A portion of the silver we use is recycled.

2 & 3. Dual Silver Plating Layers
Two carefully applied silver plating layers create a flawless, uniform surface. This precision step primes the base for optimal gold adhesion which enhances durability and radiance.

4. Palladium Barrier Layer
A critical layer that provides enhanced protection by reducing oxidation on the silver beneath. This helps preserve the jewellery’s colour and finish for longer, with the right care.

5. 18k Gold Layer
Our signature finish is genuine 18k Gold, applied with exacting thickness controls to ensure lasting quality:

• Standard pieces receive at least 1 micron plating, surpassing typical industry norms.
• Vermeil pieces feature a substantial 2.5 microns, providing extra depth and durability.

6. Nano-Ceramic E-Coating
This cutting-edge coating adds an additional layer of protection against abrasion, environmental wear, and daily exposure. Commonly used in advanced fields like automotive and aerospace, nano-ceramic technology brings a level of durability that’s not often seen in jewellery, a thoughtful detail we’re proud to include.

Finally, every piece is meticulously hand-polished to precision, enhancing its shine and smoothness. Unlike mass-produced pieces polished by machines, our hand finish ensures each item receives personal care and attention, resulting in a refined surface you can both see and feel.

We review detailed test reports for every batch to help ensure our materials and plating meet our standards. Plating thickness is measured at three separate points on each piece to support evenness and consistency, a careful step that goes beyond common practice.

4 Rigorous Quality Tests

Our plating process is only part of what makes our jewellery exceptional. Each batch piece undergoes four thorough quality tests designed to confirm it will withstand the demands of daily wear:

1. Abrasion Testing
Simulating everyday friction, we ensure the plating maintains its finish without fading or scratching prematurely.

2. Chemical Resistance Testing
Pieces are exposed to common substances like sweat, skincare products, and pollution, confirming their durability in real-world environments.

3. Heat and Humidity Testing
We replicate conditions from hot climates to humid days, ensuring your jewellery maintains its integrity no matter the season or setting.

4. Transportation Durability Testing
Each batch is tested for shock and movement to ensure your jewellery can handle transportation, shipping, and handling, arriving secure and intact, ready to wear.

1 Thoughtful Standard: A Commitment to Love, Respect, and Intention in Every Step

It means valuing the hands of the people who bring each of our designs to life. Honouring their craft, time, and dedication, knowing that jewellery is the result of human connection.

It means choosing materials responsibly, with every decision considering the well-being of both people and the planet. Love in our process is about mindful choices that reduce harm and promote sustainability.

It means designing mindfully, focusing on timeless and minimal designs so our pieces can become a meaningful part of your life—a companion to your most special moments and milestones.

This one thoughtful standard guides every decision we make; how we work, how we source, and how we care for each piece. It ensures the jewellery you wear reflects not only beauty and quality, but a thoughtful commitment to craftsmanship, ethical responsibility, and genuine connection.

This is the heart of everything we do. When you choose BY TONIN, you choose jewellery made with care that goes beyond the surface.
