Unusually large single octahedral Microlite crystal. The crystal is dark green and translucent and mostly complete all around (missing the bottom tip as shown). Ex. Carl Acosta collection. Carl acquired this out of Jean Smith's personal collection. Jean was an owner of 'The Rocksmiths' dealership who travelled to Brazil frequently on buying trips. Although Microlite is not listed on MINDAT as occurring from Brumado, Brumado has produced a wide number of rare and unusual species and I am going with Jean's locality information.
