Pyrite Specific Gravity Explained: Density, Bulk, and Relative Values

Well, let me tell ya ’bout this stuff called pyrite. Some folks call it fool’s gold ’cause it looks like real gold, but it ain’t. It’s a mineral, a kind of iron sulfide, and it comes from a big ol’ family called the pyrite group. Now, you might be wonderin’, what’s so special ‘bout this here pyrite? I’ll tell ya, it’s got a heap of things worth knowin’.

First off, the weight of pyrite, or its specific gravity, is pretty high. It weighs around 5.01 times heavier than water. In simpler words, if you was to drop a chunk of pyrite in a big ol’ bucket of water, it’d sink right to the bottom, real quick. Now, compared to other minerals, that’s quite heavy! Most minerals don’t weigh that much, but pyrite sure does. That’s why it ain’t so easy to carry around in yer pocket if it’s big enough.

Pyrite ain’t no soft thing neither. It’s got a hardness between 6 and 6.5 on the Mohs scale. That means, if you try scratchin’ it with something like a copper penny, it ain’t gonna leave no mark. It’s tough, like a rock, and it ain’t gonna give up easy. Some folks might try to say it’s weak just ’cause it looks shiny, but let me tell ya, it’s got some fight in it.

You’ll find pyrite in all sorts of places. It grows in a lot of rock types, all over the world, but it’s most common in coal beds, like the ones you might find in southwestern Indiana. I reckon that’s where it’s found most. You might even find it in little bits in the rocks that are scattered ’round the place, like when you’re diggin’ through dirt or rocks. But it ain’t always easy to find, you gotta be lookin’ real close to spot it, since it don’t always stand out in a crowd.

Now, the color of pyrite is something to talk ’bout too. It’s usually a pale, brassy yellow, kinda like gold but not quite the same. Sometimes, it even gets darker over time and turns into a pretty tarnished shade, with some iridescent colors mixed in. It’s shiny too, like a metal, and when it breaks, it does so in what they call a ‘conchoidal fracture,’ which just means it breaks in smooth, curved shapes, kinda like glass.

There’s somethin’ else I should mention, the bulk density of pyrite. That’s just a fancy way of sayin’ how much pyrite weighs for its size. It’s got a bulk density of about 4.84 grams per cubic centimeter. Don’t worry, I ain’t expectin’ you to do the math! Just know that it’s dense stuff, and it packs a lot of weight into a small space. Now, if you’re holdin’ a chunk of pyrite, you’ll sure know it’s heavier than it looks.

Folks might not realize, but pyrite has a lotta uses. People been usin’ it for all sorts of things, even though it ain’t the same as real gold. Some folks say it’s a good material for making sulfuric acid, and others use it in making certain types of batteries and stuff. But mostly, it’s just admired for its shiny golden look, even though it ain’t worth as much as the real gold. It sure is pretty though, and some folks like to keep it just for that.

So, in the end, pyrite might not be gold, but it’s got its own special charm. It’s heavy, tough, shiny, and easy to find if you know where to look. If you happen upon some pyrite out in the field or in the dirt, you might just think you struck it rich, but once you get to know it better, you’ll realize it’s just fool’s gold, still, worth a look and worth a story or two.
