Is it really possible to get stunning jewelry that looks and feels incredible, but is made from sustainably sourced materials that don't damage the environment?
I decided to find out. But I realized quickly I couldn't do it alone. The lovely Mrs. Miller was only too happy to help me find where to buy eco-friendly jewelry in the U.S.
Diamonds might be a Girl's Best Friend - but they can be the worst nightmare for the planet and the people who mine them.
Later, I’ll go into more detail about exactly what to look for when shopping for ethical and environmentally friendly jewelry.
But first, I’d like to introduce you to the best sustainable jewelry brands that impressed the hell out of me and Mrs. M.
✔ Ethical Sourcing
✔ Blockchain Verification
✔ Diamond Upgrades
Why It's the Best Overall: Brilliant Earth combines traceable, ethically sourced materials with exceptional designs and a lifetime warranty. It is the most comprehensive and trustworthy choice for sustainable jewelry that I researched and tested.
Why It's Recommended for Engagement & Wedding Rings: The brand offers blockchain-verified diamonds to help address the trust issue regarding authenticity with engagement rings. This is one of many reasons why I chose Brilliant Earth as my #1 pick for engagement rings.
Personal Experience: I thoroughly researched Brilliant Earth when shopping for my wife's birthday gift. I wanted to buy her a diamond necklace because she was born in April and diamonds are her birthstone. Brilliant Earth let me trace the diamond's origin from a specific mine through cutting and setting.
The Brilliant Earth necklace I ordered has exceeded my expectations. My wife wears it regularly, and the setting has held up well through normal wear. The yellow gold chain feels durable and shows no signs of tarnishing, unlike some of her other jewelry.
My research did highlight some cases of stones falling out of settings within months of purchase. I've never experienced such issues, and Brilliant Earth assures me that it resolves any problems like this quickly under warranty.
Brilliant Earth offers a diamond upgrade program that provides original purchase credit toward a new diamond, meeting minimum value thresholds (natural ≥ 1.5×, lab-grown ≥ 2×). This is a great way to refresh your jewelry in the future if your taste changes or your budget increases.
✔ 365-Day Returns
✔ Factory-Direct Savings
✔ Value & Luxury
Why It's the Best for Value & Choice: Quince cuts out intermediaries and sells directly from the factory, meaning you can pay up to 50% less than at traditional jewelers.
The range of jewelry at Quince is impressive for a brand that doesn't specialize solely in jewelry. It sells lab-grown diamond rings for over $4,000, but also offers value options (such as hoop earrings for under $30).
Quince's 365-day return policy for most items helps remove the risk from buying jewelry online. It is easily the most generous returns policy of all the brands I tested. The next best is MiaDonna at 60 days.
Personal Experience: Quince's jewelry made it onto my testing list because I wanted to see if its factory-direct pricing model delivered quality. It did!
I ordered a Cuban Curb Chain Necklace for myself and the 14K Gold Everyday Hoops for my wife. Both pieces arrived within a week, and the gold weight felt substantial (not the hollow, flimsy stuff you sometimes get from budget jewelry brands).
Quince's 14K gold chain has held up remarkably well. I've worn it continuously for two months, including in saltwater and through daily showers, and it shows no signs of tarnish or wear. My wife's hoops have also maintained their shine and shape despite her wearing them almost every day.
✔ Inclusive Sizing
✔ LGBTQ+ Identities
✔ Feminist & Women-Owned
Why It's the Best for Inclusivity: Bario Neal stocks ring sizes 2-16 and will custom-fit necklaces and bracelets to your measurements. All designs are inclusive for all genders, and LGBTQ+ affirmation has been a part of Bario Neal since it was founded in 2008. No rainbow washing here, just total inclusivity!
Personal Experience: I researched Bario Neal when my wife and I decided our wedding anniversary deserved something more meaningful than the standard jewelry store experience.
Bario Neal caught my attention with its women-owned credentials and complete supply chain transparency, which goes beyond the vague claims some jewelers use. The brand uses 100% recycled precious metals or Fairmined-certified gold, and their lab-grown diamonds carry the SCS-007 Sustainability Rating, which proves carbon neutrality.
Bario Neal crafts all jewelry in-house at their Philadelphia studio or collaborates with expert American makers. This US-based production allowed me to request design revisions and CAD renderings before work began, and the designers understood precisely what I wanted.
We love the final result (his and hers bracelets), and the quality matches what you'd expect from fine jewelry built for heirloom passing.
✔ Supporting Social Causes
✔ In-Store Pickup
✔ Heirloom Quality
Why It's the Best for Minimalist/Dainty/Everyday Jewelry: Catbird specializes in thin, stackable 14k gold jewelry you can wear every day. Catbird's solid recycled gold withstands constant wear with minimal risk of tarnishing. A limited range of silver and platinum pieces is also available, but high-quality gold is where Catbird excels.
Personal Experience: Catbird caught my attention after my wife mentioned wanting everyday jewelry she could wear in the shower or during workouts. She tested a Catbird chain and ring for two months, and neither piece has tarnished or irritated her skin.
Catbird's stackable designs are ideal for those who want to build a collection over time, rather than purchasing everything at once. My daughter stacked three Catbird rings together for a college semester, and they survived gym sessions and beach trips without losing their finish.
The brand donates at least 1% of its sales to nonprofits year-round, and you can pick up orders in-store.
Catbird jewelry offers a 20-day return window and includes a two-year warranty. This is an acceptable level of cover, but it's not the best available at the brands I tested and approved. If returns and warranty are important to you, take a look at Quince (they offer 365-day returns and a lifetime warranty).
✔ Free US Returns
✔ Custom Designs
✔ Lifetime Defect Warranty
Why It's the Best for Classic Timeless Jewelry: Noémie avoids trendy details that date jewelry quickly. They specialize in timeless favourites such as solitaires, halos, pavé bands, and tennis bracelets. Noémie's jewelry showcases the stone and metal, and will still look classy in decades to come.
Personal Experience: Noémie's custom design service helped me secure the perfect gift for my mom on her retirement. I wanted to create an easy-to-open/close diamond necklace with my mom's initials, as she has arthritis and struggles with clasps on most jewelry.
Noémie's design team responded within a few hours of my initial email and sent three sketches based on my description and budget.
When the final piece arrived, it perfectly matched the design I had envisioned. The 18K gold feels substantial, and the certification confirms the authenticity of the diamonds.
Noémie's custom ordering process requires patience because orders take 1-6 weeks to arrive, which almost caused problems with my mom's retirement party timeline. Her necklace arrived exactly on the estimated date (the day of the party!), but last-minute gift buyers should stick to Noémie's ready-to-ship collection.
✔ Protecting Sensitive Ears
✔ Swimming & Workouts
✔ Surgeon Recommended
Why It's the Best Earrings for Sensitive Skin: Tini Lux makes its earrings from medical-grade titanium that's lab-tested to ensure it contains no nickel. This is important if you suffer from sensitive skin because "nickel allergy is usually related to earrings and other jewelry", according to Mayo Clinic.
The skin-safe nature of Tini Lux earrings is also backed up by Dr. Adrian E House, MD (a Board-Certified plastic surgeon).
In an interview with Tini Lux in 2023, Dr. House said, "I recommend Tini Lux to my patients. The hypoallergenic and nickel-free earrings not only minimize the risk of adverse reactions but offer a wide range of stylish options. With Tini Lux, my patients can enjoy beautiful earrings without compromising their comfort or skin health."
Tini Lux specializes in earrings for sensitive skin. If you're looking for a jewelry brand that offers more than just earrings for sensitive skin, consider Brilliant Earth, Bario Neal, and MiaDonna. All three have a wider range than Tini Lux and offer some options suitable for sensitive skin.
Personal Experience: I tested Tini Lux earrings after Mary, my wife's work colleague, asked for help with her metal allergies. She gets rashes from almost everything she tries, and her ears turn red every time she wears conventional jewelry.
Mary wore a pair of Tini Lux hoops for three months straight without a single reaction. She showers in them, exercises in them, and sleeps in them without the usual irritation or tarnishing she's had with "hypoallergenic" jewelry.
✔ One-Of-A-Kind Pieces
✔ Direct Communication
✔ Carbon Offset Shipping
Why It's the Best for Vintage/Second-Hand Jewelry: Finding high-quality vintage & second-hand jewelry can mean sorting through thousands of pieces from different eras. Etsy solves this problem by bringing together independent sellers into a single searchable marketplace. The platform sells pre-loved jewelry at lower prices than new, while reducing demand for newly mined materials.
Etsy also lists new jewelry, and some options are cheaper than the brand I selected as the best value for money (Quince). However, during testing, the new jewelry I purchased from Quince felt higher in quality than similar-priced new pieces from Etsy.
Personal Experience: I tested Etsy when helping my daughters source unique Mother's Day gifts for my wife. We purchased a vintage moonstone ring from a Star Seller in Oregon and a handmade pearl necklace from an artisan in North Carolina. Both sellers responded to my questions within hours and provided detailed information about materials and sizing.
The moonstone ring arrived with a handwritten care card that proved the seller's attention to detail. The pearl necklace was well-made, featuring a knotted chain and secure clasp construction.
Etsy leaves materials verification, authenticity confirmation, and quality standards to individual buyers rather than imposing uniform requirements across its marketplace. To avoid disappointment, I recommend that you examine the photos closely, request detailed specifications, and study the seller's reviews before making a purchase.
✔ Charitable Donations
✔ B Corp Verification
✔ Lab-Grown Specialization
Why It's the Best for Lab-Grown Diamonds: MiaDonna sells only lab-grown diamonds - no mined stones at all. Every diamond comes with an IGI, GIA, or GCAL grading report and is set in recycled precious metals. MiaDonna holds B Corp status and donates at least 10% of net profits to The Greener Diamond Foundation.
Brilliant Earth, Quince, Bario Neal, and Catbird also sell lab-grown diamonds. However, when it was launched in 2005, MiaDonna claimed to be the first retailer dedicated exclusively to lab-grown diamonds and gemstones. I consider them to be experts in growing diamonds and the ideal place to start your search for high-quality lab-grown diamond jewelry.
Personal Experience: MiaDonna impressed me when I researched and tested the brand for my article on engagement rings. So, when my wife needed new stud earrings after losing a pair on a beach trip, I ordered her MiaDonna ones as a surprise.
The Round Lab Grown Diamond Classic Four Prong Stud Earrings I chose were heavier and more substantial than her previous studs. The lab-grown diamonds are stunning. They score a 10 on the Mohs hardness scale and have a lifetime guarantee against clouding or fading.
MiaDonna produces most pieces to order, which can result in a wait of a few weeks for delivery (my order took 11 days to arrive). However, some ready-to-ship items are dispatched the same day if ordered before 11 AM PST.
My wife and I personally researched, purchased, and tested each piece with help from friends and family over several weeks of real-world use. Every item was worn, cleaned, and inspected, not just unboxed and photographed.
When rating each brand, we considered the following criteria.
We combined these findings into our overall star ratings for each brand. We rejected more than 10 brands that did not meet our criteria.
All products were purchased at full retail price, and none were gifted, sponsored, or provided in exchange for review. No brand is permitted to pay for inclusion or position in our roundups.
The jewelry industry is linked to high carbon emissions, excessive water consumption, water and air pollution, and chemical spills.
The following statistics help us to understand the importance of choosing sustainable jewelry.
Choose an ethical and sustainable brand to ensure your jewelry purchases don't contribute to this environmental damage.
Here's an overview of what sustainable practices to look out for,
A jewelry brand is sustainable when it makes beautiful pieces without causing unnecessary harm to people or the planet. That means paying attention to where materials come from, how they’re made, and who’s involved at every step.
Look for brands that do the following.
Using recycled gold, silver, and platinum avoids new mining. This helps cut waste, energy use, and pollution (as demonstrated by the statistics above).
Brands using recycled metals for jewelry include Brilliant Earth, Quince, Bario Neal, Catbird, and MiaDonna.
Recycled materials are always preferable. But when brands do use newly mined gold and silver, make sure they use Fairmined or Fairtrade suppliers. That means they at least treat workers fairly and protect local environments.
Sustainable brands use responsibly sourced diamonds and colored stones that come from conflict-free sources.
Many now use lab-grown diamonds that have the same chemical and physical properties as mined diamonds, including identical hardness and durability (Gem Society).
When produced with clean energy, they also cause far less land and water disturbance than traditional mining (Zhdanov et al., 2024).
Workshops that use non-toxic materials, reduce water waste, and run on renewable energy are much better for both workers and the planet.
Long-lasting designs reduce the need for fast-fashion jewelry that quickly ends up in landfill.
It also means you don't need to buy replacements, which cost you more money and cause more mining.
Truly sustainable jewelers have an ethos of full transparency. I expect brands to share information about where their materials come from.
I recommend studying the full traceability of any jewelry piece you buy. Make sure everyone in their supply chain earns a fair wage and works in safe conditions.
Look for companies that go the extra mile by using recycled or FSC-certified packaging and carbon-neutral shipping options where available.
To help you identify brands that meet these standards, you can look for trusted certifications and independent audits.
Certifications help you tell which jewelry brands meet real ethical and environmental standards instead of relying on marketing claims. Each label focuses on a different part of the supply chain, so seeing more than one is a good sign.
Here are the main labels to look for.
Having selected a brand that meets your environmental and ethical standards, here's how to care for your jewelry collection so that it lasts as long as possible.
Gentle cleaning and careful storage are usually enough to make sure your timeless pieces really do stand the test of time!
Use the following tips to care for your eco-friendly jewelry.
Both recycled and Fairmined reduce the environmental impact of gold, but they address sustainability in different ways.
Newly mined gold produces about 302 times more CO₂ than recycled gold. That breaks down to 53 kg CO₂-eq per kg of reccled, compared with roughly 16,000 kg (16 t) CO₂-eq per kg for newly mined (Fritz et al, 2020).
Recycling is clearly the lower-impact choice environmentally, and is therefore my preferred option
If you need new gold, then the Fairmined certification is best for important social and ethical benefits.
Yes, eco-friendly jewelry brands offer good value for money, provided you choose the best ones.
While it’s true that a sustainable fine jewelry brand, like Brilliant Earth, has pieces costing many tens of thousands of dollars, there is still value for money to be found if you shop around.
Yes, Mejuri is eco-friendly. We did test some Mejuri pieces for this roundup, and I was happy with the company's ethics and responsible practices.
However, my wife didn't particularly like the items she tried. We also felt it was slightly overpriced for the quality.
After searching online, I found an excessive number of Mejuri reviews saying they were a "waste of money". We wouldn't necessarily go that far, but we agreed that other brands offer better value.
That's why we decided not to recommend them at this time.
According to Chelsey Grasso of Remake, “Cartier has chosen to take a leading role in advancing ethical code in the jewelry industry. Their gemstones are sourced from suppliers who share the company’s values, and Cartier requires a Statement of Warranty for every diamond-related invoice they receive”.
According to the BBC, Pandora has pledged to focus solely on lab-grown diamonds.
This article highlights that sustainable jewelry brands do not have to cost the earth. Both literally and financially.
The best jewelry companies don’t just use sustainable materials. They also have green business practices, materials, and fair trade policies, ensuring that everyone in the supply chain (from mine/lab to store) is treated fairly and paid what they’re due.
True sustainability comes from not consuming needlessly. Investing in a handful of quality, sustainable pieces of jewelry that will last a lifetime is one way to reduce the environmental impact of your fashion choices. Timeless jewelry never goes out of fashion!
Finally, a big thanks to my better half again for her input into this article. Always very much appreciated. It looks like I might have to return the anniversary scarf I ordered :)
