A fine combination specimen that includes the very rare species, londonite, the cesium-dominant analogue of rhodizite. Two gemmy and lustrous, sharp londonite crystals to 1.5 cm with pastel-yellow color dominate a quartz-rich pegmatite vein that includes lustrous, cranberry-red liddicoatite crystals. It is uncommon to see both londonite and liddicoatite in such richness together in a specimen.
