Andy Lucas, GIA’s education manager of field gemmology, researches and documents the mine to market journey of gemstones. Lucas shares the changes he observed in Colombia’s major emerald mining and cutting areas in a presentation he gave at the 2017 JCK Las Vegas show. 

Lucas interviewed local participants in the emerald trade to see what is causing the changes in Colombia’s emerald business. He learnt that there is a generational shift in approaches to mining and that the government is working to standardise the industry. The main effort is focused on combining traditional and modern mining methods to advance Colombian emeralds in the global market. 

In the video, Lucas discusses the five pillars of the Colombian government’s mining plan, introduced in October 2015 during the Emerald Symposium in Bogotá. The plan is meant to formalise, regulate and provide help for geological studies and infrastructure. The goal is to create a balance for the country’s indigenous people and the publicly traded companies.
