Gem mining in a granitic pegmatite 4-6 meters wide with a length of 200 meters. Noteworthy as the type locality of pezzottaite.

Located in the northern part of the Ampandramaika-Malakialina pegmatite field in the central highland of Madagascar, about 140 km south of Antsirabe.

The pegmatite is hosted by marbles belonging to the Vohimena group. Mining started here at the beginning of the 1940s by French colonists, and in November-December 2002 a large cavity containing multicolored tourmaline and deep pink crystals was discovered. The deep pink crystals, which were first designated "raspberry" beryl (béryl framboise), were later shown to be a new mineral species, pezzottaite (Laurs et al. 2003).
