La galena es un mineral del grupo de los sulfuros. Forma cristales cúbicos, octaédricos y cubo-octaédricos. Su dureza en la escala de Mohs es de 2,5 a 3. 1 La disposición de los iones en el cristal es la misma que en el cloruro de sodio (NaCl), la sal marina. Su fórmula química es PbS . Químicamente se trata de sulfuro de plomo aunque

It has a distinct silver color and a bright metallic luster. Galena tarnishes to a dull gray. Because lead is a primary element in galena, the mineral has a high specific gravity (7.4 to 7.6) that is immediately noticed when picking up even small pieces. Galena is soft with a Mohs hardness of 2.5+ and produces a gray to black streak.

· Physical Properties of Galena. Galena is a very soft mineral, registering only 2.5 on the Moh's hardness scale. And even worse, galena has perfect cleavage and brittle tenacity. This means that specimens are very easily damaged by just a tiny chip or bruise. When dropped or smashed, galena easily splits into tiny cubes.
