Since we started making jewellery more than 20 years ago, we have understood that the provenance of the precious metals we work with and stones we set, form a part of the inherent beauty of our pieces. We are constantly looking for ways in which a small business like ours can work to improve the traceability and sustainability of the materials we use and the practices we follow.

At our core


Each piece at McCaul Goldsmiths is designed, made and set in-house, in either our Dublin or London ateliers, ensuring complete transparency in our making process and reducing the carbon footprint of each piece. Customers and visitors to both our London and Dublin ateliers are welcome to take a look around the workshop to understand our processes and to meet the makers and designers who will craft your piece. Being a small outfit plays to our strengths and allows us to be agile in making sustainability commitments which are really important, both to us as makers, and to our customers, such as using 100% recycled gold as standard.



We aim to create timeless pieces to be worn and treasured for your lifetime and beyond. To ensure your piece lasts the test of time, drop into us at either of our Dublin or London ateliers for for a free yearly care and maintenance check. We love to see our pieces again and it is always a pleasure to catch up with our customers.  



We have thoroughly reviewed and researched our precious metal supply chains from a sustainability, environmental and ethical perspective and this is something that we continue to do on an ongoing basis. As a result we offer our customers three options when choosing the precious metal for their piece: recycled gold and platinum, which we use as standard; Fairtrade gold; or, the ability to reuse the customers own metal.

option 1:

Recyled gold & Platinum

Reduce, reuse, recycle is as relevant in the jewellery world as it is any walk of life. We only use 100% recycled gold and platinum in our pieces as standard (although at its origin all gold will have been mined initially, even if it that took place a hundred or more years ago).



All of our pieces at McCaul Goldsmiths are made individually and can be made using Fairtrade Gold.  Fairtrade Gold is sourced exclusively from mines which meet the Fairtrade Gold Standard; an internationally recognised marker of best-practice.

An independently audited set of benchmarks created by Fairtrade International connects goldsmiths, such as us here at McCaul Goldsmiths, to miners, through a transparent and traceable supply chain. The Fairtrade certificate ensures workers in these small scale gold mines earn a guaranteed minimum price for their gold. They also receive a premium to spend on improving their businesses or on community projects, such as education, clean water and healthcare. Fairtrade Gold Standard includes strict requirements on working conditions, health and safety, handling chemicals, women’s rights, child labour, and protection of the environment including water sources and forests. Although there is a slight cost differential to use Fairtrade Gold in any given piece, at McCaul Goldsmiths we have taken the decision not to profit from the use of Fairtrade metal over regular metal. We are proud to be part of the Fairtrade goldsmiths scheme, find us here: McCaul Fairtrade details.

option 3:

Re-using your own jewellery

Sometimes our customers love to re-purpose pieces of jewellery they already own, for sentimental reasons as well as environmental considerations. Although it can be more labour intensive than obtaining gold from our gold suppliers, because of the nature of the work involved in melting a customer’s gold, if it is possible to do so we love to give pre-loved pieces of jewellery a new lease of life. If you would like to understand the process in greater detail, we would love to hear from you.



We work with a small number of trusted gemstone and diamond suppliers who we know personally and with whom we have developed strong relationships with over the years. We only buy from suppliers who guarantee that their stones are ethically sourced. Our stones are carefully chosen for their provenance, quality and beauty. We are constantly adding to our collection, selecting stones for their vivid colour, unusual cut, rarity or sparkle.

The coloured gemstones in our Fairtrade collection are sourced from Wennick–Lefèvre, a gem company that specialises in natural and responsibly mined and cut gemstones. Their unique supply chain has been created with an ethical focus, measured by the level of engagement and positive impact on the local communities within which they work. From mine to market, Wennick–Lefèvre operates throughout the entire supply chain, ensuring full transparency.

the kimberley process


At McCaul Goldsmiths we only use conflict-free diamonds in our jewellery and all our diamonds are only ever sourced from suppliers that comply with the Kimberley process. In 2003, the Kimberley Process Certification Scheme was established to prevent "conflict diamonds" from entering the mainstream rough diamond market. Conflict diamonds, also referred to as blood diamonds or war diamonds, are diamonds that originate from areas that are controlled by forces, factions or corrupt governments responsible for fuelling conflict and wars. The Kimberley Process works by ensuring that all transactions involving the sale and purchase of diamonds include clear statements guaranteeing that the diamonds are of ethical origin. All of the diamonds used in our jewellery are sourced from suppliers that comply with the Kimberly Process.

We also offer the option to use Canadian diamonds, which can be found in our curated diamond section.

Lab-grown diamonds offer an alternative to a mined-diamond and can be sourced for bespoke projects.

Heirloom gemstones 

At McCaul Goldsmiths we are very happy to work with heirloom gemstones, we would need to assess their quality and suitability before setting but giving new life to an existing gem is something we love to do. Take a look behind the process with this beautiful commission here. If you are interested in something similar, we would love to hear from you.
