Odulio Jose Marensi de Moura, a Brazilian citizen, received his geology degree from the University of Rio Grande do Sul, Brazil in 1976, and gemology degree from Universidad Autonoma de Madrid, Spain in 1983.

 

Over 40 years of active explorations, he has explored for both commercial gemstone mining and industrial minerals in the pegmatite Provinces of Brazil. During which he has worked as a geologist in many gemstones mines such as Golconda, Chiá, Aricanga, Cruzeiro, Pederneira, and Santa Rosa/Mutuca among others even in the Batalha Mine (the original place for “Paraiba Tourmaline”).

 

For close to twenty (20) years, he has worked for the renowned Idar-Oberstein firm of Paul Wild OHG as manager and geologist. The company started at Quintos Paraiba Tourmaline Mine, Rio Grande do Norte, Brazil, and later they have done explorations for Cu-bearing tourmalines, alexandrite and emerald mine in Bahia, Minas Gerais, Paraiba and Rio Grande do Norte, among others in the same Country.
