Ampasogona (Ampasagona) pegmatite, Tetezantsio-Andoabatokely Pegmatite Field, Andrembesoa Commune, Betafo District, Vakinankaratra Region, Antananarivo Province, Madagascar
Miniature, 5.0 x 4.3 x 3.9 cm
One of the finest rhodizite specimens I have seen in recent years, due to the rich color, excellent luster, and sharpness of the crystal (which is 1.6 cm across). This material is rhodizite, though unusually Rb-rich, and is not the same as Londonite: the relatively Cs-dominant analogue of Rhodizite named after Dr. David London. This specimen was exchanged from Madagascar specialist Dr. Federico Pezzotta. From anybody else, I would have gone ahead and labeled it as Londonite as they tend to be more lustrous and yellow than the pure rhodizites. 5 x 4.3 x 3.9 cm
