Galena and sphalerite commonly occur together and darker varieties of sphalerite may initially be confused with galena. Pure sphalerite samples can be distinguished from galena because they are harder (3.5 to 4) and have a lower specific gravity (3.9-4.1). The color of their streak provides an even simpler way to distinguish the two.GUID ( UUID V4 ): f0d391fe-5b7f-4c8d-8fe6-dd0720e3f5f1.
