Almost every jeweller now has a sustainability page, and most of them say roughly the same things. Conflict free. Recycled gold. Ethically sourced. The words appear so consistently, and are so rarely defined, that they have stopped carrying much information.
This guide is our attempt to be useful instead. It explains what the common certifications and claims actually cover, what they demonstrably do not, and which widely repeated statistics do not survive being looked up. Some of what follows makes our own marketing harder rather than easier. We think that is the point of writing it.
The short version
- "Conflict free" is a much narrower claim than it sounds. It refers to a specific certification scheme that covers rough diamonds only and defines conflict very tightly.
- "Recycled gold" is a claim about where metal came from, not evidence that less gold was mined. The evidence for the second thing is weak, and we will not pretend otherwise.
- Fairtrade and Fairmined gold are the most rigorous certifications available — and together they accounted for roughly one hundredth of one percent of newly mined gold last year.
- Buying nothing mined is not automatically the ethical choice. Tens of millions of people depend on small-scale mining, and the OECD's guidance is to engage with it rather than avoid it.
- The lowest-impact piece is one made from materials that already exist. That is not a slogan; it is the only claim on this page that nobody seriously disputes.
What "conflict free" actually certifies
The phrase almost always refers to the Kimberley Process Certification Scheme, in force since 2003, with 60 participants representing 86 countries.
Its definition of a conflict diamond is precise, and worth reading slowly: rough diamonds used by rebel movements or their allies to finance conflict aimed at undermining legitimate governments.
Three limits follow directly from that wording, and none of them are controversial — they are visible in the scheme's own published FAQ.
- It covers rough diamonds only. Polished diamonds do not require a Kimberley Process certificate. The scheme governs shipments between countries, not the stone in a finished ring.
- It addresses rebel financing, not harm generally. Labour abuses, child labour, environmental damage and violence carried out by governments and their own security forces all fall outside the definition.
- It certifies shipments, not mines and not jewellers. No jeweller is Kimberley Process certified, because that is not a thing the scheme does.
You will also see the claim that over 99.8% of diamonds are conflict free. That figure comes from the scheme's own estimate that conflict diamonds are under 0.1% of world production — measured against its own narrow definition. It is a self-assessment of a specific problem, not an independent finding that 99.8% of diamonds are free of human rights or environmental harm.
Critics of the scheme are not fringe. Global Witness, which helped create it, resigned as an official observer in December 2011, saying that nearly nine years in, most consumers still could not be sure where their diamonds came from. At the November 2025 plenary, a proposal to widen the definition to cover militias, criminal networks and private military companies failed to achieve the required consensus, as similar proposals have before.
What we take from this. Kimberley Process compliance is worth having and we would not buy from a supplier without it. It is a floor, not a guarantee, and any jeweller presenting it as a complete ethical answer is either not reading it or hoping you will not. Our natural diamonds are GIA certified, conflict free and Kimberley Process compliant, and the reason we also talk about our direct relationships with miners and cutters is that the certificate alone does not tell you enough.
Recycled gold, and the claim we will not make
We use recycled gold and silver wherever possible, and where you bring us your own metal it goes straight back into your piece. Both are true and both are worth doing.
What we will not tell you is that this reduces gold mining. Here is why.
Gold is effectively indestructible and has always been recycled heavily. In 2025, according to the World Gold Council, recycling supplied 1,404 tonnes of a total 5,002 tonnes — around 28% of supply, roughly where it has sat for decades. In the same year, mine production hit a record 3,672 tonnes.
More importantly, recycling volumes track the gold price and economic distress, not jewellers' purchasing decisions. Research commissioned by the World Gold Council found price movements explained around 75% of the variation in recycling volumes. People sell gold when gold is expensive or when they need money. A jeweller choosing recycled stock does not change how much ore comes out of the ground.
There is a definitional problem as well. The LBMA has acknowledged that it, the Responsible Jewellery Council and individual refiners all use different and incompatible definitions of "recycled", and that the term has been used as a marketing device. The RJC tightened its own definition in 2024 specifically to prevent greenwashing, excluding investment bars and coins because due diligence on them is impractical.
And on carbon: the independent responsible-sourcing specialist Christina T. Miller describes the claim that recycled gold reduces carbon emissions as questionable and complicated at best. If you see a jeweller quote a specific percentage reduction, ask what it is measured against.
So the honest framing is this. Recycled gold is a defensible statement about the origin of our material and about not sending offcuts to landfill. We run zero-wastage systems and remelt filings, offcuts and old settings because waste is waste. It is not a defensible statement about reduced mining or reduced emissions, and we are not going to make it one.
Fairtrade and Fairmined: the strongest option, and its real size
If you want gold whose origin is genuinely known and whose extraction demonstrably benefited the people who did it, these two schemes are what exist.
Fairmined, run by the Alliance for Responsible Mining, and Fairtrade Gold, run by Fairtrade International, both certify artisanal and small-scale mining organisations against standards covering legal operation, environmental protection, labour conditions and traceability. Both guarantee a minimum price of 95% of the market rate plus a cash premium paid directly to the mining community — USD 2,000 per kilogram for Fairtrade, USD 4,000 for Fairmined, and USD 6,000 for Fairmined Ecological, which prohibits toxic chemicals entirely.
Unlike "recycled", these are claims about a named, audited origin. They are the real thing.
They are also very small. Fairtrade reports 316 kg of gold exported under its terms in 2025. Fairmined reports 101.2 kg sold worldwide in the same year, from around a dozen certified mining organisations in Peru and Colombia. Together that is roughly 417 kg, against 3,671,600 kg of newly mined gold — about one hundredth of one percent.
We think that number should be published more often than it is. It does not mean the schemes fail. It means buying certified gold delivers a real, audited benefit to a specific community, and it does not yet shift the industry. Those are different claims and only the first one is currently true.
Why avoiding mined material is not automatically ethical
This is the part that most sustainability pages leave out, because it complicates the story.
Artisanal and small-scale mining is not a marginal activity. The World Bank puts direct employment at at least 45 million people across 80 countries, with hundreds of millions more in related work, and describes it as the largest non-farm rural employer in most mineral-rich countries. It supplies somewhere around a fifth of the world's gold, though estimates vary — the World Bank and World Gold Council say about 20%, while UNEP puts it at 12 to 15%.
The harms are real too, and we are not romanticising it. Small-scale gold mining is the largest human source of mercury emissions to air, and in this kind of mining virtually all the mercury used ends up in the environment. The published estimates carry very wide error margins, so we will not quote a precise tonnage.
But the conclusion the sector's own governance bodies draw is not "avoid it". The OECD's due diligence guidance for gold explicitly directs companies to deal directly with legitimate artisanal producers where possible, warns against measures that harm vulnerable groups including legitimate small-scale miners, and devotes an appendix to creating economic opportunities for them. The World Bank's position is that the answer is formalisation, not exclusion.
A jeweller who buys only recycled metal has not helped a single small-scale miner. That is not an argument against recycled metal. It is an argument against treating it as a complete ethical position.
What mining a ring's worth of gold actually involves
You may have seen the claim that a single gold ring generates 20 tonnes of mine waste. It is worth knowing where that comes from, because we see it repeated constantly without attribution.
It originates with the campaigning organisation Earthworks, publicised in 2006 and calculated from 2001 production data for a specific ring: 18 carat, one third of an ounce. Earthworks describes its own figure as conservative, because it excludes overburden and waste rock from underground mines for which no public data existed. It has never been peer-reviewed and, as far as we can find, never independently updated.
So: not invented, but advocacy-produced, a quarter of a century old, and tied to a ring heavier than many modern settings. We would rather give you the arithmetic that is not disputed. Open-cut gold ore typically runs somewhere around one to four grams of gold per tonne of rock. At those grades, recovering a single gram of fine gold means processing on the order of a tonne of ore before any waste rock or stripped surface material is counted. And the direction of travel is unhelpful: S&P Global reported in 2023 that average gold head grades had fallen 13.4% since 2010, meaning more rock moved per gram today than when the Earthworks figure was calculated.
The point is not to make you feel bad about a ring. It is that the material has a real weight behind it, which is the strongest argument there is for using material that has already been extracted.
Australian stones: what we can defend, and what we cannot
A good deal of what we work with is Australian — parti and ink blue sapphires from the Australian fields, Australian opal, Australian champagne diamonds. We are asked what that guarantees. Here is the accurate answer.
What it does mean. Australian mining operates inside an enforceable legal framework. In Queensland, gemstone mining claims are capped at one hectare, granted for up to ten years, and although small-scale operations are exempt from requiring a full environmental authority, they must comply with the Small Scale Mining Code and lodge financial surety before starting, rehabilitate to a safe, stable and self-sustaining landform, and complete that rehabilitation within a year of finishing. In New South Wales, claim holders must file proof of rehabilitation and can forfeit their security to the Crown if they do not. Australian labour law, workplace safety law and the statutory minimum wage apply to everyone working a mine here. None of that is true everywhere.
What it does not mean. There is no chain-of-custody certification for Australian coloured gemstones equivalent to Fairtrade or Fairmined for gold. The Queensland surety amounts are modest — a band running from a few hundred dollars to around twenty-three thousand. And the framework is not flawless: in 2023 the NSW government had to run a validation programme covering 3,343 opal mining claims, of which 1,230 had been invalidly granted, affecting hundreds of miners at Lightning Ridge.
It is also not accurate to describe Australian sapphire as uniformly artisanal. There are many genuinely small operators and fossickers in the Queensland and New England fields, and there is also at least one large commercial producer working dozens of licences in the Central Highlands. "Australian" tells you about the jurisdiction and the law. It does not by itself tell you the scale of the operation your stone came from.
One clarification on champagne diamonds specifically, because the timing matters. The Argyle mine in Western Australia — which produced over 865 million carats across its life and more than 90% of the world's pink diamonds — ceased mining on 3 November 2020. Australian champagne and coloured diamonds in the market today therefore come from stock mined before that date, not from current production. That is worth knowing, and if anything it counts in their favour: no new ground is being opened to supply them.
What we actually do
Rather than restate the adjectives, here is the specific list, and we are happy to be held to it.
- Our natural diamonds are GIA certified, conflict free and Kimberley Process compliant. Our lab-grown diamonds are IGI certified. We will always tell you which you are looking at, on the product page and in the room.
- We keep direct relationships with gem miners and cutters, which is the reason we can usually tell you where a stone came from rather than only which dealer sold it to us.
- We use recycled gold and silver wherever possible, on the material-origin basis described above rather than as an environmental claim.
- We run zero-wastage systems. Offcuts, filings and old settings are collected and remelted.
- Client metal goes straight back into the client's piece.
- We focus on ethically mined coloured stones, a good deal of them Australian.
- Everything is made by hand in Melbourne, largely to order, rather than produced offshore in volume against a forecast.
On lab-grown stones we have written separately and at length, because the environmental argument there is more contested than either side admits. Our guide to lab-grown versus natural diamonds covers stone origin, certification, real prices from our own rings, and why we decline to call lab-grown the green option.
Questions worth asking any jeweller
Including us. A jeweller who cannot answer these, or who becomes vague, has told you something.
- Where did this specific stone come from? Not the supplier — the country, and the mine if it is known. "We can't trace it" is an acceptable answer if it is true and said plainly.
- Is it natural or laboratory-grown, and will you put that in writing?
- When you say recycled, whose definition are you using?
- Is the certification for the rough stone or the finished piece?
- What does your certification not cover? This is the most revealing question on the list.
Worth knowing that this is a widespread problem rather than a local one. Human Rights Watch's 2020 review of fifteen major jewellery and watch brands, together representing around 15% of global jewellery sales, rated none of them excellent, and found most could not identify the mine of origin for their gold or diamonds.
The option that beats all of this
Every argument on this page is about degrees of harm in producing new material. There is one choice that steps outside it.
A piece remade from stones and metal you already own requires nothing newly mined and nothing newly grown. No certification scheme is needed, because no supply chain is involved. It is the only genuinely uncontested environmental claim in fine jewellery, and it happens to produce the pieces people are most attached to.
If you have inherited jewellery sitting unworn, our guide to modernising family heirlooms walks through what can be done with it and, just as importantly, when we would advise leaving it alone. Remodelling & Heirlooms has before-and-afters.
And if you are starting from nothing, that is fine too — just ask us the questions above. If what you are planning is an engagement ring, our guide to designing a ring for someone else covers stone, setting, metal and size in order. Otherwise, book an appointment, start an enquiry, or email info@whitenovember.com.au. We would rather give you an inconvenient answer than a comfortable one.
