MineralService - Brazil: 19 Dec - 26 Dec 2023

Here a large selection of fine minerals I collected or purchased during my numerous mineralogic trips into Brazil ; since January 2004 to January 2023 I organized 18 field trips visiting Minas Gerais, Rio Grande do Norte, Paraiba, Espirito Santo, Rio de Janeiro and San Paulo states.
Always collecting in mines and visiting the local dealers, I discovered three new specie: Matioliite in Gentil mine, Jahnsite-(NaMnMg) and Jahnsite-(MnMNMg) in Sapucaia mine, Minas Gerais.
