Business Practices

At Mari Thomas we strive to do better and want to create better business practices to support positive action towards caring for both people and planet.

We believe that little differences within small businesses, such as ourselves, will make for big environmental change across the World. More so, given the rapid globalisation of the jewellery market and the use of stones and metals mined from every corner of the Earth.

Therefore, we are committed to being as responsible from the way we make our jewellery in our in-house workshop, to the precious metals and stones we source.

GOLD AND SILVER

As a small team, we consciously try and manage or develop ways in which we can tread lightly on our planet and reduce our environmental footprint. Before “sustainable” became the hot topic in the fashion and jewellery world, Mari had ALWAYS crafted jewellery pieces with recycled gold and silver. We prefer to use gold and silver metal that is recycled over mined and fair-mined to ensure we are gentle on our planet, preventing environmental pollution and damage.  

Inside the workshop, the engineering side of jewellery, we collect and gather fine dust and all old scrap metal to reuse in our jewellery collections. Nothing is or was ever wasted!

All our collections are made from recycled gold and silver

DIAMONDS

We only use conflict-free and ethically sourced natural diamonds and gemstones, as well as offering lab-grown diamonds as an alternative, sustainable option.

We have always worked very closely with our stone dealers to ensure that our mined stones have all been sourced following fair labour practices and sustainable agreements. This measures the effect on people, communities, and our social
footprint. Helping to ensure fair play, safe working conditions, environmentally sound practices, and that no human rights have been abused.

We have always and will always work only with ethically sourced diamonds and gemstones, and will not handle any stone if its provenance is unknown or in question.

OUR JEWELLERY WORKSHOP

As a trained jeweller and goldsmith Mari is proud to support a small dedicated team of jewellers in her workshop producing and working with her on her jewellery commissions and collections.

The main workshop is nestled inside Mari Thomas Gallery supporting our local economy and celebrating craftsmanship. It is on view and is a big part of the unique experience of visiting the gallery.

To limit the amount of plastic used within the gallery and reuse whenever we can. In the workshop and we store each jewellery item using recyclable and naturally biodegradable glassine bags and our dispatch boxes are made from recycled material and are fully recyclable.

We occasionally work with other specialists within the industry like casters and hand engravers, most are based in or around Birmingham's jewellery quarter, where Mari Thomas originally trained. It Is also the location of her hallmark (Birmingham Assay Office), and we are proud to say that all the work is made in the UK with sustainable and ethical materials. In-house, we are always implementing little changes.

PLATINUM

Due to a new health warning flagged by our casting companies, recycling old platinum in a cast project exposes a health risk at high temperature, as unknown alloys contain metals that are toxic when released at high temperatures and enclosed spaces. Platinum is now sourced from new, from sources they know are safe. (If you have any platinum jewellery that you would like remodelled, please get in touch, there are still options available).  

OUR PACKAGING

Mari Thomas boxes and bags are all recyclable. They are not made from recycled materials as the trees used to produce them are replaced as part of the production so therefore it completes the cycle by planting more trees.

Our tissue paper is all made from recycled paper and is recyclable. We encourage to reuse and recycle wherever possible.

Collectively, the small changes we make together can make a big difference.
