Malakialina A.4

Situated 140 km NW of Fianarantsoa in the central highland of Madagascar on the left side of the Matsiatra river, about 5 km from its confluent with the Manantsahala river.
The pegmatite is famous for the largest beryl crystal found:
18 meters long, 3.5 meters diameter, estimated volume of 143 cubic meters and an estimated weight of 380,000 kilos.
Closed in 1963 after have producing about 2000 tons of beryl and 32 tons of columbite-tantalite.
This locality is also marked Malakialina A.4 to distinguish this locality from Malakialina F.3, a pegmatite found just south of this locality.
