Pearl farming has the potential to offer unique opportunities in terms of livelihoods and marine conservation in the Pacific region.

What we do

This research project is examining how the marine cultured pearl supply chain and consumers could further support these positive environmental and socio-economic benefits and promote responsible pearl farming.

How we do it

We are working in collaboration with pearl farmers and other partners in Switzerland, Japan, the US and the Pacific region. This website aims to inform about different pearl types, ecological and socio-economic dimensions of pearl farming and to share resources and findings on these themes.
