Sphalerite is a zinc sulfide mineral that serves as a primary ore of zinc. It comes in various colors, including brown, yellow, red, and black, and exhibits perfect cleavage and a resinous to adamantine luster. While it can be faceted for jewelry, its softness (Mohs hardness 3.5 to 4) makes it less common in this use. Metaphysically, sphalerite is believed to enhance personal power, creativity, and emotional balance.
