I switched to ethical jewelry five years ago and I’m sharing the best engagement rings. The best ethical engagement rings are made with recycled or Fairmined metals and lab-grown fully traceable gemstones, without conflict, mercury, child labor or unaudited mining.

I’m explaining what makes a jewelry brand ethical, what to look for and my favorite brands actually doing the work.

Why Choose Ethical Jewelry

It comes down to this: the jewelry you wear starts as rocks and metal dug out of the ground. It’s why the term “blood diamonds” exists, because people paid with their blood and lives to mine them. Child labor is still found in small-scale gold and gemstone mining, which the UN considers the largest source of mercury pollution in the world.

• Safer for your skin: Ethical brands often skip nickel, lead and cadmium, which are common in cheap fast fashion jewelry.
• Kinder to the planet: No environmental toll, no new land disturbed, no cyanide or mercury runoff.
• Responsibly sourced (no child labor): Fair wages and safe conditions for miners and artisans, with no child labor.
• Built to last: Quality materials like solid gold and sterling silver hold up for years instead of tarnishing or turning your skin green.

What Makes an Engagement Ring Ethical?

Today’s jewelry brands often say they’re sustainable, eco friendly and ethical, but they can be buzzy marketing lingo. If you look deeper most of them aren’t truly ethical or transparent. Here’s what to look for when buying an engagement ring:

• Recycled metals: Gold, platinum, and silver that’s been melted down from old jewelry, industrial scrap, or dental gold.
• Fairmined / Fairtrade gold: A certification that proves gold is sourced from small-scale, artisanal mining communities that meet strict environmental and labor standards, and that are paid fair, transparent prices for their work..
• Lab-grown diamonds: These are chemically, physically, and optically identical to mined diamonds, but grown in a controlled lab environment rather than pulled from the earth.
• Beyond the Kimberley Process: Brands that are tracing diamonds to specific mines or regions with verified labor and environmental standards.
• Traceability / blockchain verification: The gold standard for transparency and the ability to track a diamond’s exact journey from mine to setting.
• Mercury-free gold: Brands that actively avoid mercury mining. A lot of artisanal gold mining still uses mercury to separate gold from ore — a process that’s harmful to miners’ health and to local water systems.

Every brand on this list meets these standards.

Questions to Ask Before You Buy

A note on price: ethical doesn’t have to mean expensive. Lab-grown diamonds and recycled metals are often more affordable than mined metal.

Catbird Engagement Ring

Catbird is one of New York’s most beloved jewelry brands and over 95% of their gold is recycled, and every brilliant cut diamond in the line is either reclaimed or lab grown. Their in-house collection is handmade by its own team of jewelers in a studio at the Brooklyn Navy Yard, inside a LEED certified building, Catbird is also a member of 1% for the Planet and has given more than $2.3 million to nonprofits through their Catbird Giving Fund. Its recycled gold figures are self reported rather than independently certified, but for delicate, made in New York fine jewelry, it’s one of the most transparent brands out there. I visited their cozy and welcoming San Francisco, California location and got to see so many styles in person.

I tried Brilliant Earth Lab Diamond Engagement Ring

Brilliant Earth is probably the biggest and most well-known name in ethical fine jewelry, with showrooms across the US and a huge selection of ethical engagement rings and wedding bands. I have their 18K White Gold Lab Diamond Ring with 0.72 Carat Round Lab Created Diamond, in Super Ideal Cut, H Color, VS2 Clarity and find it to be elegant, dainty and feminine. Brilliant Earth’s natural diamonds are sold under its Beyond Conflict Free standard, which goes further than the Kimberley Process, they removed Russian diamonds, offer lab grown diamonds and publishes a yearly mission report with its audit results. If you’re going to visit their physical store I recommend making an appointment because they don’t take walk-ins when they’re busy.

Bario Neal Engagement Ring

Bario Neal is one of the most rigorous ethical jewelers I’ve come across. All of their precious metal is either 100% recycled or Fairmined certified, and every colored gemstone is fully traceable to its source, with most sapphires coming from Montana. If the studio can’t trace a stone, they won’t set it. Diamonds are recycled or come from Australia and Canada, and its lab grown diamonds carry SCS sustainability ratings. Rings are handmade in house in Philadelphia or with American makers, and most are made to order in about four to six weeks. The designs are organic and modern, with lots of unique stones and settings, making it a beautiful choice for anyone who wants a one of a kind engagement ring.

I tried Catori Life Mare Ring and Neptune Shell Ring

Catori Life ethical jewelry is entirely nickel free, allergen free and made from reclaimed metals, including bronze, sterling silver, and recycled 10K, 14K, and 18K gold, paired with ethically sourced natural stones. What sets Catori apart is their design: the pieces are inspired by ancient symbols and talismans like the serpent, the ankh, and the lotus, with an organic, slightly imperfect finish that feels organic in nature. A Catori engagement ring is perfect for a more bohemian bride, lover of the esoteric or someone who’d rather have a one-of-a-kind heirloom than a classic solitaire. I love that their Mare ring is cast from a real shell gathered on a Puerto Rican shoreline, so every bit of its natural texture is preserved in recycled sterling silver, bronze or gold. I have it in sterling silver, and love how high quality and shiny it looks (will need regular polishing though!). I also got their Neptune Shell Ring made entirely with solid recycled bronze and I love that it’s a symbol of protection, intuition and renewal

Do Amore Engagement Ring

Do Amore makes their ethical engagement rings in New York and I love their ethos and effort to be a source of good. The jewelry company is 100% founder and employee owned, and all of its gold, platinum, and palladium is recycled. You can choose from Canadian diamonds, conflict free African diamonds that come with a blockchain record tracing them from mine to ring, recycled diamonds, or lab grown diamonds, some grown with solar and hydro power. Every purchase funds clean water for one person through community water projects, and you even get the GPS coordinates and a photo of the well your ring helped build.

Fejn Engagement Ring

I love fejn’s minimalisti, puristic and affordable luxury approach to ethical fine jewelry. Every piece is designed in Cologne and handmade from recycled 925 sterling silver or recycled 9K and 14K solid gold, and the fine jewelry uses lab grown diamonds and gemstones instead of mined ones. Production happens with selected manufacturers in Thailand, which fejn says it audits for working conditions and human rights, using the Responsible Jewellery Council’s standards as a guide. Even the boxes are FSC certified cardboard. I love the look of the Hammered Sparkle Ring, a dainty 1.5 mm band with a finely hammered texture and a tiny sparkling stone that catches the light without feeling flashy. It’s a great everyday stacking ring and alternative engagement ring if you love a minimalist look. Just know the gold version is 18K gold plated over recycled sterling silver, and the stone is cubic zirconia rather than a diamond, so take it off before swimming, showering, or applying lotion to keep the plating looking its best.

Gardens of the Sun Engagement Ring

Gardens of the Sun is one of the most transparent and ethical jewelry brands that ships worldwide. Instead of relying on recycled metal, they source mercury-free gold mined by Dayak women in Central Kalimantan, Indonesia, who are paid fairly, with half of the premium going into a fund that supports their community. They also meet the miners, even creating partnerships with indigenous communities, and work with independent cutters as much as they can. It’s one of the most globally impactful brands I’ve seen making ethical engagement rings. Their gold is never mined with mercury or cyanide and their diamonds are fully traceable coming from from Kalimantan, along with stones from Arkansas, Australia, and Botswana. Their engagement rings are custom made to order and take about 8-12 weeks to make.

Vintage and Heirloom Rings: The most sustainable engagement ring is one that already exists. A vintage or heirloom ring requires no new mining. If you have a family stone, some brands on this list can reset it for you – I recommend Bario Neal for their excellent work. When buying vintage, be sure to for a recent appraisal or grading report, check whether the ring can be resized, and buy from sellers with a clear return policy.
