Recycled gold

What is recycled gold?

Recycled gold is gold that has already been extracted from the ground at some point in the past, collected from existing sources, and reintroduced into the supply chain rather than mined afresh ⁽¹⁾. It can come from several sources, including old jewellery, dental work, electronic components such as circuit boards, and offcuts from jewellery manufacturing workshops ⁽²⁾.

How is it refined?

Before recycled gold can be used in new jewellery, it must be refined. The raw collected material is melted down, then put through chemical or thermal purification processes – such as the Miller or Wohlwill method – which remove impurities and alloy metals until only pure gold remains, typically reaching a purity of 99.9% or higher ⁽³⁾. The refined gold is then recast into grain or bars ready for a jeweller to use. Because gold is chemically stable and handles high heat without degrading, it can be recycled and refined any number of times without any loss of quality ⁽⁴⁾.

Is it the same quality as newly mined gold?

Yes. Once properly refined, recycled gold is chemically identical to newly mined gold. It does not tarnish faster, is not more fragile, and carries no physical trace of its previous life ⁽⁵⁾. A ring made from recycled gold is hallmarked in exactly the same way as one made from newly mined metal, and the hallmark will show the same purity – 375 for 9ct, 750 for 18ct, 950 for platinum ⁽⁶⁾.

The environmental case

The main reason buyers choose recycled gold is environmental. Gold mining involves moving large volumes of rock, using significant energy, and in some operations, chemicals that can pollute surrounding land and water ⁽⁷⁾. Recycling gold avoids the need for those mining operations and requires substantially less energy. The gold already exists above ground – it simply needs to be recollected and refined, rather than dug up again ⁽³⁾.

The key limitation: traceability

The most important thing to understand about recycled gold is that it cannot be traced back to a specific mine or source. Once old jewellery and scrap from various places is melted together in a refinery, the original origins of the metal are impossible to separate ⁽⁸⁾. This means recycled gold reduces the demand for new mining, but it does not actively improve conditions for the miners who are still working. It is an environmental choice, not a social one.

It is also worth knowing that the definition of "recycled gold" used in the industry can include offcuts from manufacturing workshops – meaning some material labelled as recycled may have come from recently mined gold that was simply processed and partly returned as scrap. Not all recycled gold comes from end-of-life consumer items ⁽⁹⁾.

Recycled gold vs Fairtrade and Fairmined gold

Two alternative certified options are available from some UK jewellers: Fairtrade Gold and Fairmined Gold. Both involve gold that is newly mined, but from small-scale mines that meet independently audited standards for fair pay, safe working conditions, and reduced use of toxic chemicals. Miners receive a guaranteed minimum price plus an additional premium invested into their communities ⁽⁸⁾. Fairmined adds stricter environmental requirements, including the elimination of mercury from the extraction process ⁽¹⁰⁾.

The practical difference is this: recycled gold is better for reducing the environmental impact of new extraction, while Fairtrade and Fairmined gold actively support the people currently working in the mining industry. Neither option is perfect, and both are considered significantly preferable to standard commercially mined gold. The right choice depends on which priority matters most to the buyer ⁽⁸⁾.
