This document summarizes the work of the Working Group for Artisanal and Alluvial Diamond Production at a meeting in Washington DC. It discusses the group's efforts to implement recommendations around improving traceability, regulating artisanal mining and trade, reducing illicit cross-border trade, and encouraging miners to enter the formal economy. Some progress was made, but many challenges remain, including bringing more informal actors into the regulated system and addressing conflicts between miners, businesses, and other stakeholders. The group hopes an upcoming seminar will help address these ongoing issues in artisanal mining.
