At the core of PBS is a commitment to taking responsibility for the brand’s contributions to an industry infamous for unethical and environmentally hazardous practices. As a result, every aspect of the brand’s environmental and ethical contribution is evaluated: metal materials are sourced from artisanal and small-scale mining operations that produce Fairtrade and Fairmined gold and silver; stones are locally sourced and cut; products are produced in limited runs, in-house by Martin and a small production team; and the brand limits carbon emissions through restricted carbon-neutral shipping methods.
