About

The First Comprehensive Knowledge Platform for Gemstone Sustainability

Gemstone Sustainability is the first comprehensive, open-access knowledge and research platform dedicated to advancing sustainability across the global gem and jewellery industry, with a particular focus on artisanal and small-scale mining (ASM).

We bring together scientific research, industry insights, educational resources and practical knowledge to explore the environmental, social and economic dimensions of gemstone mining, processing, trade and responsible sourcing.

Our mission is to make knowledge accessible, foster interdisciplinary research and connect researchers, mining communities, industry professionals, policymakers and civil society.

Through research publications, educational programmes, field expeditions, expert discussions and international events, we bridge the gap between scientific knowledge and practical action, contributing to a more responsible, transparent and inclusive gem and jewellery industry.

From Sri Lanka to the World

Gemstone Sustainability is an initiative by Gem Trail Lab, a Sri Lanka-based social enterprise advancing responsible gemstone supply chains and artisanal mining through research, technology, innovation and collaboration.

Rooted in Sri Lanka’s gemstone heritage and mining communities, our platform takes a global perspective, connecting knowledge, people and ideas across borders and disciplines.
