Miniature, 5.4 x 4.3 x 4.0 cm
Antsongombato, Betafo, Madagascar
Most newly found and named species are micro-crystals, but this is the exception. Named for University of Oklahoma mineralogy professor, David London, this is the rare, cesium rich analog of rhodizite - and it is a beautiful mineral species, luckily for him! From the type deposit in Madagascar, this large, well formed crystal measures 3.0 cm across and is aesthetically perched on matrix. It is lustrous and translucent with a vivid sulfur yellow color. Rare, large, with luscious color, this is an awesome specimen from the collection of Federico Pezzotta, a specialist in mineralogy of Madagascar and discoverer of Pezzotaite.
