About the locality
Sakoany (in Katsepy, Boeny) is Madagascar's classic locality for blue celestine, noted for having produced tonnes of pale to medium blue crystals. After its discovery in 1967, workings began on the seashore itself, then moved a few hundred metres to higher ground (+15 m). Today the deposit is worked by numerous small, irregular pits in the ground that reach 15 metres in depth.
