11 Certified sustainable Fine Jewelry Brands

Ethical jewelry focuses on people: fair trade and fair wages, safe working conditions and transparency. It looks at the ethical and responsible sourcing of materials like gold, silver, gemstones and diamonds.

Sustainablejewelry focuses on the planet: reducing waste, pollution and carbon emissions, carbon offsetting, ecological restoration projects, non-toxic jewelry manufacturing, recycling, reusing or reducing materials, circular jewelry design, and using metals and designs made to last instead of following trends. 

The best jewelry brands do both, creating jewelry that's kind from mine to market.

Look for certifications like B Corp, Fairmined or Fairtrade Gold. Read their sourcing policy. Check if they disclose where their metals and gemstones come from. If a brand avoids giving details, that’s a red flag. True ethical jewelry brands are proud to show their supply chain.

B Corp certification proves that a brand meets high standards for social and environmental responsibility. It’s like a report card for sustainability, covering everything from worker rights to sourcing, transparency and community impact.

No. Recycled gold is often sold as the jewelry industry’s green fix, but it doesn’t actually stop mining or change anything on the ground. Gold is money, and as long as gold has value, people will keep mining it.

Recycled gold can come from the same systems that cause mercury poisoning, deforestation and unsafe labor. Some recycled gold is just illegally mined gold with a new label.

Recycled gold is the bare minimum. Ethical gold is the way forward, because real sustainability means lifting people up, not just lowering emissions on paper.

Not necessarily. Lab grown diamonds are often marketed as eco friendly because they're not mined. But that’s the surface story. In reality, most lab grown diamonds are made in high-energy facilities powered by fossil fuels, often in countries like China and India. Producing one carat of lab grown diamond can emit more carbon than a responsibly mined one. Lab grown diamonds don’t fix unethical mining or restore damaged ecosystems. They simply shift the problem (and the profits) somewhere else. 

At Gardens of the Sun, we believe sustainability is about transforming supply chains rather than avoiding them. Mining, when done responsibly, can provide income, education and opportunity for entire communities. Our natural diamonds come from known origin, and our Indonesian diamonds from artisanal miners. 

Yes, many affordable sustainable jewelry brands are small makers with direct-to-consumer pricing to keep costs fair. They offer both fair value and responsible sourcing.

Fair trade jewelry ensures fair wages, safe working conditions and environmental protection for miners and artisans. It supports communities instead of exploiting them: jewelry that’s as fair as it is beautiful.

Non-toxic jewelry is made without harmful substances like mercury, lead, arsenic, cadmium, cyanide or nickel. These chemicals can cause skin irritation, allergic reactions and even lead to serious health problems. Unlike cheap costume jewelry, which often uses unknown base metals or low quality plating that wears off over time, non-toxic jewelry is crafted from materials that stay safe, even with daily wear. It protects miners, makers and you.

Jewelry has always been madefor women, but for most of history, it hasn’t been madeby them. The jewelry industry has long been dominated by men: from mine owners to major brand CEOs. Women wear the jewelry, yet they’re often missing from the decision making tables that shape how it’s sourced, priced and presented.

Choosing women owned jewelry brands helps rebalance that story. It means supporting women who design, lead and redefine what luxury looks like. It puts money, opportunity and creative power into the hands of the very people this industry was built around. Buying from women owned jewelry brands is a simple way to vote for equality and inclusion with your purchase.
