One good example of traceability is a Swiss jewellery company that invested for three years with several artisanal mines in Latin America, helping them improve their standards, reach fair trade certification, and then source from those mines. They know exactly where their gold is coming from, they know exactly what kinds of conditions it's produced under, and they have really invested in supporting those mining communities. That's a very good example of what a company can do.
