sphal·er·ite

 (sfăl′ə-rīt′)
n.
The primary ore of zinc, occurring in usually yellow-brown or brownish-black crystals or cleavage masses, essentially ZnS with some cadmium, iron, and manganese. Also called blende, zinc blende.

[Greek sphaleros, slippery, deceitful (from its being easily mistaken for galena) (from sphallein, to trip, from sphalos, fetter, pair of stocks; akin to Sanskrit skhalate, he stumbles, and Armenian sxalem, I stumble) + -ite.]

sphalerite

(ˈsfæləˌraɪt; ˈsfeɪlə-)
n
(Minerals) a yellow to brownish-black mineral consisting of zinc sulphide in cubic crystalline form with varying amounts of iron, manganese, cadmium, gallium, and indium: the chief source of zinc. Formula: ZnS. Also called: zinc blende
[C19: from Greek sphaleros deceitful, from sphallein to cause to stumble]

sphal•er•ite

(ˈsfæl əˌraɪt, ˈsfeɪ lə-)
