Sustainability at Oia

Sustainability isn’t a destination — it’s an ongoing commitment.

At Oia, we believe jewellery should be made with intention, care, and respect for both people and the planet. While no jewellery brand can be 100% sustainable, we are committed to making thoughtful choices at every step of our journey — and to being open about where we are, and where we’re going.

Our pieces are designed to last, to be worn daily, and to hold meaning — not just for you, but for the world around us.

Product

Designed to Last

The most sustainable jewellery is jewellery that lasts.

Oia pieces are designed to be worn often, layered effortlessly, and kept for years — not seasons. By focusing on durability, timeless design, and quality materials, we aim to reduce overconsumption and encourage mindful ownership.

Thoughtfully Chosen Materials

We carefully select materials that balance durability, beauty, and responsibility.

Recycled 925 Sterling Silver

Our silver is made from recycled sources, reducing the need for new mining while maintaining the same quality, strength, and finish you expect.

Ethically Sourced Gold

As part of our commitment to circularity, we prioritise recycled gold. If newly mined gold is used, we ensure they adhere to international standards and certifications.

Stainless Steel

Stainless steel is a durable, highly corrosion-resistant, and water-resistant metal, making it extremely comfortable to wear daily.

Recycled Brass

Sourced from trusted suppliers, every recycled brass piece is layered with white bronze for resilience, then plated with either 18ct gold or 925 sterling silver using electrolysis.

Gemstones

Where gemstones are used, we work with trusted suppliers who prioritise ethical sourcing and responsible practices.

Pearls

We use cultured pearls from oysters and freshwater mussels that we carefully select for our pieces. Pearls are sensitive in nature, so make sure to treat them with love.

Lab-Grown Diamonds

Our lab grown diamonds feature the same physical and chemical properties as natural diamonds and are a solid option for those seeking great value and incredible diamond payoff.

Responsible Production

Our jewellery is crafted in partnership with trusted manufacturers who share our values.

We work closely with suppliers who follow fair labour practices, provide safe and respectful working environments, meet recognised ethical and quality standards

We believe strong relationships informing transparency are essential — not just to ensure accountability, but to create jewellery we are truly proud of.

Sustainable Packaging & Delivery

Every order has an environmental footprint — and we take responsibility for ours.

We design our packaging to be as thoughtful as the jewellery inside: Plastic-free for reuse and longevity.

We also work to minimise emissions across our deliveries and operations. Where possible, we choose zero-emission deliveries. This allows us to offset the carbon impact of shipping while continuing to explore ways to further reduce our footprint.
