Width of view approximately 50 cm.Easily confused with: Halite (no effervescence, is cubic), gypsum (no effervescence, scratched by fingernail),fluorite (no effervescence, cannot be scratched by penny) Calcite Hardness: 4 (cannot be scratched by fingernail or penny, can be scratched by a steel knife) Cleavage: 4 directions, but your sample may be badChalcopyrite is a striking, bright yellow, metallic mineral that occurs in nearly all sulfide deposits. Initially, it may be easy to confuse chalcopyrite, or copper pyrite (CuFeS2), with pyrite (FeS2), but the two can be distinguished by their relative hardness and chalcopyrite’s iridescent tarnish.

Halite, better known as rock salt, can easily be distinguished by its taste. Since taste is an important property of salt, there is a right way to taste a specimen of halite (or an unknown mineral that is similar to halite) and a wrong way. The right way is to first lick your index finger, rub it against the specimen and then taste the finger. Besides hardness, the biggest difference is how the two minerals break. Quartz breaks in curvy and irregular shapes (conchoidal fracture). Feldspar, however, breaks readily along flat faces, a property called cleavage. ...
