Cumengeite, Boleite
Thumbnail, 1.8 x 1.4 x 1.2 cm
Amelia Mine, Santa Rosalia (El Boleo), Boleo District, Mun. de Mulege, Baja California Sur, Mexico

These 3 pictures do not do the specimen justice...this is a unique, 3-dimensional specimen featuring an untwinned 1 cm Cumengeite perched caddycorner on the side of a 1 cm boleite cube. I have never seen the like! Most such associations are imbalanced or the cumengeite covers up the boleite completely. This is showy, complete all around, and relatively large for what is available anywhere outside the cases of the Sorbonne. I think it makes for a competition-level thumbnail or rarity specimen. 1.8 x 1.4 x 1.2 cm
