Londonite, Liddicoatite, Quartz
Antsongombato gem mine, FKT Antsentsindrano, Andrembesoa Commune, Betafo District, Vakinankaratra Region, Antananarivo Province, Madagascar
Miniature, 5.0 x 4.6 x 4.0 cm
A fine combination specimen that includes the very rare species, londonite, the cesium-dominant analogue of rhodizite. A large, gemmy and lustrous, 3.0 x 2.8 cm, sharp londonite crystal with pleasing pastel-yellow color dominates a quartz-rich pegmatite vein that includes lustrous, cranberry-red liddicoatite crystals (second photo). It is uncommon to see both londonite and liddicoatite in such richness together in a specimen. The large londonite crystal is pristine, which is uncommon in itself.
