OUR MAKERS
Behind every piece are people whose care and skill bring it to life. We choose to work with a partner who shares our values, where people are treated with dignity, quality is honoured, and the environment is respected. Certified by the Responsible Jewellery Council (RJC), they ensure every step of the journey, from traceable raw materials to the finished piece, upholds responsible practices and protects both people and planet.
Their workplaces are fair, safe, and supportive, recognised by Intertek, a globally recognised organisation that reviews working conditions, safety, and wellbeing. This commitment includes empowering women and minorities, supporting parents through flexible working arrangements, providing fair wages that allow makers to live with stability and respect, and offering opportunities for everyone to develop new skills and grow in their roles.
Care for the environment is considered in every process. Energy is used thoughtfully, waste is carefully minimised, and resources are managed with care. These practices are continually refined to reduce impact, which is reflected in ISO 14001 certification. Alongside this, ISO 9001 certification helps ensure every stage of production is consistent, precise, and carried out with care.
Recycled metals are used wherever possible, and processes are designed to reduce environmental impact without compromising quality. Each piece carries the result of thoughtful craftsmanship and mindful choices, with every detail reflecting the care of the hands that made it and a deep respect for the world around us.
OUR PLATING PROCESS
We use a multi-layer plating process to ensure every piece is as durable as it is beautiful.
It begins with a strong base of sterling silver, followed by two layers of silver plating to build thickness and create a smooth, even foundation. A layer of palladium is then added to prevent tarnishing and enhance longevity. Over this, we apply a rich layer of 18k gold of at least 1 micron thick for our standard pieces, and a minimum of 2.5 microns for gold vermeil, giving each piece its warm, signature glow. Finally, an innovative nano-ceramic e-coating seals the finish, offering extra resistance to wear and everyday elements.
A refined process for a flawless finish.
QUALITY TESTING
All our pieces undergo a rigorous testing process to ensure they meet the highest standards of quality and durability.
Chemical resistance is evaluated through salt spray and sulfur dioxide tests, simulating exposure to sweat, moisture, and pollution. Surface abrasion is assessed using vibration testing, replicating daily friction and wear. Each piece is then subjected to high heat and humidity to confirm its resilience under extreme conditions. Transportation testing guarantees your jewellery stays secure and intact while on its way to you.
We also obtain detailed test reports for every batch to verify that both materials and plating meet our exacting specifications. Plating thickness is measured at three different points on each piece to ensure evenness and consistency across every surface.
Before packing, each piece is carefully hand-inspected, so you receive jewellery we’re truly proud to share.
Sustainable, Ethical Jewellery
Sustainable Practices, Premium Craftsmanship, Proven Quality
At BY TONIN, we partner exclusively with Responsible Jewellery Council (RJC) and ISO 9001 certified manufacturers to ensure the highest standards in ethical sourcing, sustainable production, and precision quality control. Every piece is crafted using a multi-layer plating process—featuring a sterling silver base, palladium anti-tarnish layer, and thick 18k gold, sealed with a nano-ceramic coating for enhanced durability and shine.
Each design undergoes rigorous quality testing, including chemical, abrasion, heat, and transit simulations, with detailed batch reporting and careful hand inspection. The result: responsibly made jewellery designed to last—crafted with integrity, and made to be worn every day.
