What sustainable jewelry means, and how to prove it.
"Sustainable jewelry" is a label that costs nothing to print. Thousands of brands use it; very few say what it means, and fewer can prove it. This guide does both: what the term actually covers, where the greenwashing hides, and how to verify a claim before you buy. The proof we'll use is our own: the independent audit of our production. A guide about verification should come with some.
What Sustainable Jewelry Actually Means
Sustainable jewelry is jewelry with its full cost accounted for: what it took to get the metal, what the work asked of the people who did it, and what becomes of the piece when you're done wearing it. In practice, that means four things at once.
- Materials. Either the material is ethically sourced and documented (Fairmined gold, traceable artisanal gems), or the material doesn't require new mining at all. We take the second path: an use recycled metals which already exist and give them a new purpose.
- Labor. The people who make the piece work reasonable hours, in safe conditions, for wages that cover the actual cost of living where they live.
- End of life. The piece is designed so its materials can be recovered and used again, not landfilled.
- Traceability. The brand can show where products come from and who verified its claims, instead of just asserting them.
These four aren't a menu; they're a single test. Recycled metal cast in an unaudited workshop doesn't pass. Neither does fair labor making pieces designed for a landfill. Either all four hold at once, or the word doesn't apply.
There's also more behind the word than marketing. In 2015, 193 countries adopted the UN Sustainable Development Goals: a shared list of what has to hold up for everyone, from clean water to fair work. Jewelry that passes the four-part test touches that list in specific, checkable places. We'll show exactly where, further down.
The Problem: Most Sustainability Claims Are Self-Reported
Search "sustainable jewelry" and read what comes up. You'll find pages that use the words ethical, sustainable, ethically sourced, and eco-friendly a dozen times without a single number, standard, audit, or name of who checked. That's the pattern to watch for. It isn't lying, exactly. It's a claim with no one standing behind it except the person selling you the piece.
Self-reporting is the core problem. A brand grading its own homework will always pass. The question that separates real sustainability from marketing isn't "does this brand care?" Every brand says it cares. The question is: who verified this, and against what standard?
Our answer is a sourcing standard, not a slogan. All of our casting and finishing, the work at the heart of every piece, happens in one facility, independently audited under Sedex SMETA 4-Pillar. Every audited claim on this page comes from that report. And the report isn't the facility grading itself: it's an independent audit firm, measuring what it found against the Sedex protocol. Not the factory's word, and not ours. Casting isn't everything, though. A small share of what goes into a finished piece doesn't yet carry the same paper trail, and we'd rather say so than stretch the claim.
Recycled Metals: The Real Story
Recycled precious metal is the same metal, atom for atom, as newly mined. Recycled sterling silver is sterling silver; recycled gold is gold. An assay office can't tell the difference, and neither can you. What changes isn't the metal. It's everything upstream of it: the extraction, the processing chemistry, and the tailings that newly mined metal leaves behind.
After refining, the metal is formed into casting grain: small pellets that let it be portioned precisely for casting. Recycled or newly mined, the grain is the same; the difference is where the metal has already been. Our jewelry is cast with recycled sterling silver and recycled jeweler's brass, with 18k gold plating on the brass pieces. Most of the metal in a new pair of our earrings has already had a previous life.
One honest limit: recycled metal by itself doesn't make a piece sustainable. Grain is melted and cast by people, and the metal says nothing about their hours, wages, or safety. That's why the next section is the one that matters most.
How to Verify Sustainable Jewelry (With a Real Audit)
The single most useful question you can ask any jewelry brand: is your production third-party certified, and what did the audit find?
Here is what our answer looks like. Our sourcing standard is Sedex SMETA 4-Pillar, one of the most widely used ethical audit frameworks in the world: independent auditors inspect the production site across labor standards, health and safety, environment, and business ethics, on a recurring cycle. Our casting partner is audited under it and additionally holds ISO 9001 (quality management), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety), all current. None of it is self-awarded, and we read every report.
The May 2026 audit found:
- Wages roughly 40% above the living wage benchmark. Auditors calculated a living wage from regional data on food, housing, healthcare, education, and transportation, then compared it with actual pay. Actual wages cleared the benchmark by about 40%. Legal minimum and living wage are not the same thing; the second is the one that matters.
- 89% of workers earn above the legal minimum wage, verified against payroll records across three pay periods.
- 99.5% of the workforce is permanently employed. No disposable contract labor.
- 63.5% of the workforce is women, and 75% of supervisors are women.
- Production water is filtered and recycled, and tested by independent laboratories.
- 474,717 kWh of onsite solar power generated in 2025.
The audit also raised findings, mostly record-keeping and safety fixes, each with a corrective deadline and a follow-up audit behind it. Some were corrected before the auditors left the building. A report that found nothing would be harder to trust. A self-reported claim never has findings; that is exactly what's wrong with it.
When a brand tells you its jewelry is ethical, this is the follow-up: who audited it, when, and what did they find?

Circular Design and Our Jewelry Take-Back Program
Most jewelry's life ends in a drawer, then a landfill. Ours is designed not to.
Circular design means the end of a piece's life is planned at the start: metals chosen and constructed so they can be recovered, re-melted, and recast. The same casting grain, around again.
It starts even earlier. Every piece is hand-sculpted as a 3D model in our Seattle studio before a single gram of metal is cast, so we make in small batches with no sampling waste and no overproduction.
The take-back program closes the loop. Send us any Astor & Orion piece you no longer wear, including a single earring whose partner is long gone, and we recycle the metal and credit you toward your next piece. Email Closetheloop@astorandorion.com and we'll take it from there.
The jewelry industry's default is to keep mining. We'd rather keep re-melting.
Sustainable Jewelry and the UN Sustainable Development Goals
Zoom out. The Sustainable Development Goals are 17 shared targets for what a livable future requires, from gender equality to climate action. Sustainable jewelry is that plan at the scale of an object you wear. Here's how the practices above map onto the goals, using audited numbers rather than aspirations. Hover any goal.
Real vs. Greenwashed: Questions to Ask Any Jewelry Brand
Six questions, and what a real answer sounds like. We can answer all six; that's the standard we think you should hold everyone to, including us.
- Who audited your production, and against what standard? A real answer names the framework: SMETA, SA8000, ISO, the Responsible Jewellery Council, Fairmined, Cradle to Cradle, or an equivalent with auditors behind it. "We personally visit our suppliers" is not an audit.
- What did the audit find? A real answer comes with numbers, dates, and sample periods. A certificate logo with nothing behind it proves the brand bought a logo.
- Do workers earn a living wage, or the legal minimum? These are different figures, sometimes very different. A brand that knows the difference will say so.
- What is the piece made from, exactly? "Recycled sterling silver" is an answer. "Eco-friendly materials" is a mood.
- What happens to the piece when I'm done with it? If the brand has no answer, the piece's end of life is your problem, and the landfill's.
- What can't you verify yet? Honest brands have a list. A brand with nothing left to improve stopped looking.
Sustainable Jewelry FAQ
Is recycled gold or silver lower quality than newly mined metal?
No. Refining erases the metal's history. Recycled sterling silver is 92.5% silver like any other sterling; recycled gold assays the same as newly mined gold. The difference is upstream, in what the metal cost the world to obtain.
How can I tell if sterling silver jewelry is actually recycled or ethically sourced?
You can't tell by looking — recycled and newly mined sterling are chemically identical, so inspecting the metal proves nothing. Interrogate the claim instead: ask who verified it and against what standard. A real answer names a third-party audit (like SMETA), a certification, and actual findings you can point to. If a brand can't name the framework or show numbers, "recycled" and "ethical" are self-reported — decoration, not proof.
What certifications should sustainable jewelry have?
Look for third-party frameworks that include audits the actual production site: Sedex SMETA covers labor, safety, environment, and ethics; ISO 14001 covers environmental management; ISO 45001 covers worker health and safety. The key word is third-party. A brand's own "promise" page is not a certification.
What is greenwashing in jewelry?
Sustainability language without verification: claims like "ethically made" or "eco-friendly" with no named standard, no audit, and no numbers. The fastest test is to ask who checked. If the answer is nobody, the claim is decoration.
Is sustainable jewelry more expensive?
Certified production costs more than uncertified production, and the difference is real: the facility is independently inspected, and the people casting the metal earn a living wage, not just the legal minimum. That's what the price of a verified piece is paying for. But sustainable doesn't have to mean luxury pricing. We work hard at efficiency, hand-sculpting each design as a 3D model so nothing is wasted on sampling rounds, and that work shows up in the price. Start with our everyday pieces: everyday collection.
How do I recycle jewelry I no longer wear?
Precious metal is endlessly recyclable; the trick is getting it back into the loop. Our take-back program accepts any of our pieces for recycling, with credit toward your next one. For other jewelry, many local jewelers and refiners accept metal for scrap value.
What does a SMETA audit actually check?
SMETA (Sedex Members Ethical Trade Audit) inspects a production site across four pillars: labor standards (hours, wages, contracts), health and safety, environment, and business ethics. Auditors review records, walk the facility, and interview workers. The 4-Pillar version is the full scope.
A sustainable piece of jewelry is one whose supply chain holds up when someone other than the brand checks. You've just seen ours checked. But nobody buys our jewelry for its paperwork. People buy our jewelry because it's simply stunning and our hand sculpted designs
