PLS Member Paolo Sanchez Presents Findings From His June 2025 Expedition to This Mineral-Rich Area
This month’s presentation by Pasadena Lapidary Society member Paolo Sanchez focuses on the famed mineral-rich districts of Minas Gerais, Brazil, following his June 2025 expedition to this region. Paolo spent two and a half weeks exploring gem- and lithium-rich pegmatites of grand proportions as part of his research to understand how the melting ancient ocean floor could contribute to making these deposits. This talk will touch upon historic gem mining in the area as well as an international rush for lithium and industrial minerals happening today, with a focus on the mining districts of Linopolis, Araçuai, and Diamantina.
Also, PLS Vice President Barna Laszlo will do a short talk on altering stones.
This month’s program meeting will take place on Tuesday, October 21, 2025, at 7:00 p.m. in the Fireside Room of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007.
