The Antsahanana quarry, situated within the Sahatany Valley near Mount Ibity in the Antsirabe II District of Vakinankaratra, Madagascar, is a renowned pegmatite locality celebrated by mineral collectors for producing complex lithium and boron-bearing species, gem tourmalines, and rare micro-minerals. Londonite is a rare cesium-rich mineral belonging to the isometric crystal system, typically forming transparent to translucent, pale yellow to yellowish-green crystals with a vitreous luster that frequently occur alongside its potassium-dominant counterpart in highly evolved granitic pegmatites.
