Bertrandite with Tourmaline
Small Cabinet, 7.0 x 4.1 x 2.6 cm
Golconda Mine, Governador Valadares, Minas Gerais, Brazil

Very few bertrandites with tourmaline are known, from this or any other pocket. This elegant specimen shows off a slender, lustrous, black schorl tourmaline measuring 6 cm in length, that has grown right through a tabular, crystal of bertrandite. Other crystals of bertrandite wreathe the base and are pearlescent and translucent, to 2.8 cm in length. A superb combo specimen!
