The exhibit is organized around the “Rose of Itatiaia” tourmaline from the Jonas Mine in Minas Gerais, Brazil. This special tourmaline is the highlight and centerpiece of the exhibition. Other “masterpiece” specimens from the most famous mines in the world include the Tourmaline Queen Mine, in California; the Paprok Region in Nuristan, Afghanistan, the Mt. Mica in Maine, the Stewart Mine in San Diego County, California; Anjanabonoina region in Madagascar, the Pedeneira Mine in Brazil; the Malkhan Mine in Russia, the Alto Ligonha region of Mozambique, etc.
