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 in marbles belonging to the Vohimena group. Mining started here in 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, that was first designed " raspberry " beryl was later showed to be a new mineral species, pezzottaite (Laurs et al. 2003).
