How Can the Jewellery Industry Reduce Its Environmental Impact?

Jewellery can last for generations, but its environmental footprint begins long before a finished ring, necklace, or bracelet reaches its owner. Precious metals and gemstones require raw materials, energy, water, processing, and transportation. The environmental consequences therefore depend not only on the final product, but also on how its materials are sourced, manufactured, used, and recovered.

Reducing this impact does not mean making jewellery completely impact-free. A more realistic goal is to reduce dependence on newly extracted resources, improve production practices, and keep valuable materials in circulation for as long as possible.

Where Does Jewellery’s Environmental Impact Begin?

For many jewellery products, significant environmental pressures can occur before manufacturing even begins.

Mining gold and other precious materials can involve land disturbance, energy consumption, water use, waste generation, and chemical processing. A life-cycle assessment of a large jewellery company found that gold and silver mining and refining were the largest contributors to environmental impacts across the assessed supply chain. The study also identified recycled precious metals and lower electricity consumption in manufacturing as important opportunities for reducing impacts.

Recent data from the World Gold Council shows why material sourcing remains important. In 2025, global gold mine production reached an estimated 3,671.6 tonnes, while recycled gold contributed another 1,404.3 tonnes to supply.

This does not mean that every mine has the same environmental footprint or that recycled gold is automatically impact-free. It shows, however, that the jewellery industry has an existing secondary source of precious metal that can reduce reliance on newly extracted material.

Can Better Diamond Choices Reduce Environmental Pressure?

Diamonds are another important part of the jewellery supply chain, but reducing the industry’s environmental impact requires looking beyond diamonds alone.

Laboratory-grown diamonds can provide an alternative to newly mined diamonds because they are produced rather than extracted from geological deposits. However, their environmental performance still depends on the resources and energy required during production. Therefore, the term “lab-grown” should not be treated as a guarantee of zero environmental impact.

Within this broader discussion, lab grown diamond rings offer another way to approach diamond sourcing, although their overall environmental impact still depends on how they are produced. The more important question is how the entire production system manages energy, materials, waste, and transparency.

The industry therefore needs to avoid presenting one material as a complete sustainability solution. Diamond sourcing is only one part of a jewellery product’s overall environmental footprint.

Recycled Gold Can Keep Precious Metals in Circulation

Gold has an important advantage from a circular-economy perspective: it can be recovered from jewellery and returned to material use after the original product reaches the end of its useful life.

Old jewellery can be collected, refined, and turned into material for new products. This can help reduce the need for additional primary extraction while retaining a valuable material within the economy.

Research published in the International Journal of Life Cycle Assessment compared high-value gold scrap recycling with mining and electronic gold scrap recycling. In the study’s German recycling system, high-value gold scrap had substantially lower energy demand and greenhouse-gas emissions than the mining dataset used for comparison. The authors estimated a global warming potential of 53 kg CO₂-equivalent per kilogram of recycled high-value gold, compared with about 16 tonnes CO₂-equivalent per kilogram in the mining dataset. These figures are specific to the systems and datasets assessed, rather than universal values for every recycling facility or mine.

Recent gold-supply data also shows that recycling is already a significant secondary source of gold. In the first quarter of 2026, recycled gold supply increased 5% year over year to 366 tonnes, according to the World Gold Council.

For jewellery manufacturers, increasing the use of verified recycled precious metals can therefore be one practical way to move toward a more circular material system.

Manufacturing Needs to Become More Resource Efficient

The environmental impact of jewellery does not end when raw materials reach a workshop or factory.

Manufacturing can require electricity for melting, forming, cutting, polishing, casting, and finishing. Production can also generate metal scrap and require water or chemicals during certain processes.

The jewellery life-cycle assessment published in the Journal of Cleaner Production specifically identified reducing electricity consumption as an important opportunity for lowering manufacturing impacts.

This means manufacturers can look beyond material sourcing and examine how efficiently their facilities operate. Improving equipment efficiency, reducing production losses, recovering valuable metal scrap, and using lower-carbon electricity can all contribute to a lower-impact production system.

A 2025 study in Cleaner Environmental Systems also examined the recovery of gold, silver, platinum, palladium, and rhodium from secondary materials. Its life-cycle assessment evaluated 20 environmental impact categories, demonstrating why precious-metal recovery needs to be assessed across multiple environmental factors rather than through carbon emissions alone.

Longer Use Can Reduce the Need for New Materials

Another environmental opportunity is often overlooked: keeping jewellery in use for longer.

Reusing and recycling jewellery can help keep products and valuable materials in circulation while reducing the need for newly extracted resources. Resale and redesign can also keep valuable metals and gemstones in circulation instead of creating demand for an entirely new product.

Longevity is not a substitute for responsible sourcing. A long-lasting item can still begin with environmentally intensive extraction. However, extending its useful life can reduce how frequently new materials and manufacturing processes are required.

This principle aligns with the broader environmental value of reducing consumption and keeping materials in use rather than treating products as disposable.

What Would a More Environmentally Responsible Jewellery Industry Look Like?

A lower-impact jewellery industry would need to address several parts of the supply chain at the same time:

• Reduce reliance on newly extracted materials where suitable alternatives exist.
• Increase responsible use of recycled precious metals and improve recovery systems.
• Reduce energy and material losses during manufacturing.
• Improve supply-chain transparency so environmental claims can be independently assessed.
• Design for durability, repair, reuse, and recovery.
• Consider the environmental footprint of the complete product lifecycle, rather than focusing on a single material.

These changes also require better information. Environmental claims should be supported by traceable sourcing information, credible life-cycle evidence, and clear explanations of what has actually been improved.

The Path Toward Lower-Impact Jewellery

The jewellery industry’s environmental impact cannot be solved by changing one gemstone, metal, or manufacturing process. The bigger opportunity lies in changing how materials move through the entire system.

Mining and refining remain important areas for improvement, while recycled precious metals can help keep existing resources in circulation. More efficient manufacturing, longer product use, repair, reuse, and better transparency can further reduce pressure on natural resources.

Jewellery production cannot be entirely free of environmental impacts, but the industry can work toward a model that extracts less, wastes less, and keeps valuable materials in use for longer. That shift would make environmental responsibility part of how jewellery is produced, rather than an afterthought added after the product is made.
