811· Sphalerite is common, but it does not often show up in casual collections of minerals, despite its occurrence in several different colors. This is perhaps because sphalerite is most commonly found in black or dark gray due to the frequent presence of iron impurities in its makeup. Sphalerite has been previously called blende or later zinc blende.
