Pyrite is the mineral whereas a pyrite 'cube' happens to be the habit in which the mineral has crystallised

Pyrite is brittle and non-malleable. It will break into smaller pieces along cleavage planes.
The place you need to scratch stays itchy until you scratch it.
the cleavage for pyrite is cubic
Aluminum can scratch zinc, but zinc cannot scratch aluminum.
Pyrite also known as "fool's gold" is a mineral that has both a different chemical, morphological and physical characteristics than gold. Gold is denser (i.e. the same size of gold is much heavier than the that of pyrite). Gold's average density is 17.64 g/cm3 while Pyrite's density is on average 5.01 g/cm3. The chemical formulas are different. Gold's chemical formula is "Au" while Pyrite's is and iron sulfate mineral with a formula of "FeS2". The color is also different, gold appears the color of gold while pyrite is more bronze in color. The crystallographic form of the minerals also vary. Gold is a very soft mineral while Pyrite is much harder (gold has a hardness of 2.5 while Pyrite is 6.5). To distinguish between a sample of each, you could scratch the surface of gold using your fingernail which you would not be able to do with pyrite. You can try to scratch it because pyrite or fools gold much harder then gold so if it doesn't scratch that much it is most likely pyrite or fools gold. You can tell them apart by looking at their reflection and streak. Also, gold is much more dense than pyrite, so the same volume would 'weigh' about 3.5 times more. Gold has a hardness of about 2.5, while pyrite is about 6 (Gold is softer and more malable). Streak is used to distinguish between Gold and Pyrite.
Hardness, luster, and scratch color help narrow down the possibilities . . . specific gravity and chemical analyses follow. As an example, gold and pyrite look about the same - both have a somewhat shiny luster. The streak color, though is black for pyrite and yellowish for gold. Hardness of pyrite is 6-something on the hardness scale, and gold is around 2.5, which is much softer.
