Sustainability
Our Commitment
Sustainability isn't a marketing word for us. It's a set of honest choices we make about the materials we use, how we operate, and what we believe jewellery should be.
The Materials We Choose
A majority of Peakful pieces are crafted from one of three core materials — stainless steel, titanium steel, or sterling silver. Each one was chosen deliberately, and each carries real environmental advantages worth understanding.
Stainless Steel
Stainless steel is one of the most sustainable materials used in modern manufacturing. It is produced with a significant recycled content — studies show that stainless steel produced via scrap-based routes uses approximately 60–80% recycled material, meaning a significant portion of every piece begins its life as something that already existed. It has one of the highest end-of-life recycling rates of any manufactured material — research by the Karlsruhe Institute of Technology found that approximately 96% of stainless steels are recycled at the end of their life. When a stainless steel piece eventually reaches the end of its life, it can be melted down and remade into a new, high-quality item without any loss of material integrity.
Beyond recyclability, stainless steel is built to last. It is resistant to rust, corrosion, and everyday wear. A piece that doesn't need replacing is a piece that doesn't end up in landfill.
Titanium Steel
Titanium is exceptionally durable and lightweight, with one of the best strength-to-weight ratios of any metal. Its longevity means pieces crafted from it are designed to be worn for years, reducing the cycle of fast consumption and disposal that contributes heavily to waste in the fashion industry. Titanium can be recycled and reused within industrial supply chains, and recycling titanium generates significantly fewer greenhouse gas emissions compared to mining and refining raw titanium ore.
Sterling Silver
Sterling silver is one of the most actively recycled precious metals in the world. According to the Silver Institute's World Silver Survey, global silver recycling reached a 12-year high in 2024, rising 4% to 194.9 million ounces. Silver has been reclaimed, refined, and reused for centuries, and the global infrastructure for silver recovery is well-established. Choosing silver as a material supports a metal with a long and documented history of circularity.
18K Gold Plating
Where our pieces feature gold, we use 18K gold plating rather than solid gold construction. This is a deliberate material choice with a meaningful difference in resource use.
Solid gold jewellery requires substantial quantities of newly extracted raw gold per piece. Gold mining is one of the most resource-intensive extraction processes in the world — it is associated with significant land disruption, high energy consumption, and environmental impact, as documented by the World Gold Council's Responsible Gold Mining Principles framework. Gold plating applies a fine layer of real 18K gold over a durable base material, achieving the same rich finish at a fraction of the raw gold that a solid gold equivalent would require.
To be precise: we are not claiming that gold plating is a zero-impact process. We are stating that, on a per-piece basis, gold plating uses significantly less newly extracted gold than solid gold jewellery of equivalent appearance — and that this represents a measurable reduction in the demand for extracted material.
Longevity Over Disposability
The single most sustainable thing a piece of jewellery can do is last. Fast fashion — made cheaply, worn briefly, discarded quickly — is one of the most wasteful categories in consumer goods. The Ellen MacArthur Foundation has identified overproduction and premature disposal as among the fashion industry's largest sources of waste. Peakful pieces are designed and priced to be kept, not replaced. Tarnish-resistant, durable materials mean your pieces hold up through daily wear, year after year. We believe the most responsible purchase is one you only need to make once.
How We Work
We operate as a direct-to-consumer brand without physical retail locations. We work directly with our suppliers and fulfil orders individually — pieces move in response to real demand rather than being manufactured speculatively in bulk. Overproduction is one of the fashion industry's largest sources of waste, and our model avoids it by design.
Note: The sustainability benefits described on this page relate specifically to our material choices and demand-led fulfilment model. We do not make claims regarding our shipping emissions or packaging at this time.
