This auction is for a large and rare matrix specimen of boleite and pseudoboleite from Amelia Mine, Santa Rosalía (El Boleo), Boleo District, Mun. de Mulegé, Baja California Sur (BC Sur), Mexico. I acquired this specimen from Jack Crawford at the Tucson Gem and Mineral Show and it was the best one that he had. It measures 8 cm by 6.5 cm by 6 cm and compares favorably with pieces I have seen sell in the four figure range. There are two main boleites (with the largest being around 7 mm across longest dimension) and a number of smaller pseudoboleites and gypsum crystals present. With a little additional cleaning/prep, this is a world-class specimen.
