A granite pegmatite situated on a small hill at the eastern shores of Lac Alaotra about 400 m NE of the village of Ambatosoratra in the Ambatondrazaka district, Madagascar. The locality is especially known for its chrysoberyl crystals, mostly from a few mm to 2 cm, but specimens up to 10 cm have been found (Behier 1960).
