Guild Gem Laboratories Brazilian Expedition visits Cruzeiro Mine

Guild Gem Laboratories visited Cruzeiro Mine this month with a group of gemology students in order to learn more about tourmalines, rubellites and Cruzeiro’s Mine pegmatites.


They had a lecture by our gemologist, visited the tunnels and had the opportunity to know the world’s largest tourmaline mine in the world!


Our CEO Douglas Neves along with Ruby Liu, President of Guild and Andrew Lucas, long time friend and VP of Guild followed the group during the whole visit.
