More and more New Zealanders are thinking about where their jewellery comes from and how it’s made. But when you come across terms like Fairtrade Gold, RJC Certified, or recycled silver, it can be hard to know what they really mean. This guide helps you understand the most common certifications and labels so you can make more informed choices next time you buy jewellery.

Why Certifications Matter

Jewellery is often associated with beauty and celebration, but behind the sparkle can lie environmental damage and poor working conditions. Mining for precious metals and gemstones uses large amounts of energy and water, and in some countries, it takes place under unsafe or exploitative conditions.

Certifications and labels bring transparency to this complex industry. They help you, as a consumer, see whether a piece of jewellery has been made with respect for people, the planet, and fair trade principles.

Discover what terms like Fairtrade Gold, RJC Certified, and recycled silver really mean. This guide explains the most important jewellery certifications and labels so you can choose pieces that align with your values and support sustainable practices.

The Most Recognised Certifications

Fairtrade Gold

Fairtrade Gold is one of the best-known certifications for responsibly sourced gold. It ensures that the gold comes from mines where workers are paid fairly and where environmental standards are upheld. The Fairtrade system sets strict rules for safety, working conditions, and the use of chemicals like mercury and cyanide. Miners also receive a premium that can be invested in community projects such as schools or healthcare facilities.

Fairmined

Fairmined certification is similar to Fairtrade Gold but managed by a different organisation. It focuses on small-scale mining and guarantees that the gold is extracted under responsible conditions. Fairmined gold can be traced from the mine to the finished piece, offering a high level of transparency.

RJC – Responsible Jewellery Council

The Responsible Jewellery Council (RJC) certification covers the entire jewellery supply chain, from mining to retail. Companies that are RJC members commit to ethical, social, and environmental standards. This includes proving where their materials come from and working to reduce their carbon footprint. Many New Zealand jewellers source from RJC-certified suppliers to ensure responsible practices.

Recycled Gold and Silver

Jewellery made from recycled gold or silver uses metal recovered from old jewellery, electronics, or industrial products that have been melted down and refined. This reduces the need for new mining and saves significant energy. However, the term recycled is not always backed by certification, so it’s worth asking your jeweller where the material comes from and how it’s verified.

Certifications for Gemstones and Diamonds

Diamonds and coloured gemstones have their own systems for responsible sourcing. The most well-known is the Kimberley Process, which aims to prevent the trade in conflict diamonds—diamonds that fund armed conflict. However, the Kimberley Process has been criticised for not going far enough, so many jewellery brands now go beyond it, working directly with trusted suppliers or using traceable stones.

An increasingly popular alternative is lab-grown diamonds. These have the same chemical composition as natural diamonds but are created in laboratories, eliminating the need for mining and significantly reducing environmental impact. Several New Zealand jewellers now offer lab-grown options as part of their sustainable collections.

How to Read the Labels

When shopping for jewellery, look for official logos or detailed product descriptions. Here are some tips:

• Check the documentation – reputable jewellers can provide certificates or traceability information.
• Watch the wording – terms like “ethical” or “sustainable” are not regulated and can be used freely. Look for specific certifications instead.
• Ask questions – a transparent jeweller will be happy to explain where their materials come from and how they are processed.

What You Can Do as a Consumer

Even without formal certifications, you can make more responsible choices:

• Choose high-quality jewellery that lasts for years – longevity is one of the most sustainable options.
• Consider vintage or pre-loved pieces – reusing existing jewellery avoids new production altogether.
• Support local designers who work with traceable materials and small-scale production.
• Take care of your jewellery so it can be repaired and reused rather than replaced.

Jewellery with a Conscience

Choosing sustainable jewellery isn’t just about following a trend – it’s about aligning beauty with responsibility. By understanding certifications and asking the right questions, you can help support a fairer and more environmentally friendly jewellery industry in New Zealand – one piece at a time.
