Supporting Our People

Cherishing Life

Responsible Manufacturing

Our jewellery is thoughtfully handcrafted before it makes its way to you. That is the quality standard behind every Marlii piece and a promise we can make because our suppliers are family. Working strictly with only family owned workshops in Italy, each specialising in a different area of manufacturing, we are able to achieve the highest level of quality balanced with the fairest price for you.

Ethical Sourcing

Working closely with mines, we have implemented programs and initiatives to ensure 100% of our gold is responsibly and ethically sourced, supporting the miners and their communities in improving their living conditions and responsible mining practices.
