Tourmaline

Size: 24 cm

Location: Alto Ligonha,Mozambique

Description: Large and gemmy elbaite crystals, green and red in color, are a hallmark of the Alto Ligonha district, but large blue to blue-green crystals are quite rare. Eight of the 27 mines in the district have produced tourmaline, though blue-green crystals like these are known in particular from the Naipa pegmatite. Green crystals are rarely over 4 cm.
