What mineral is this?

[ZachSS]

I was just curious, because it's pretty cool looking. It's heavy and rough.

ZachSS,
First off don't know that it's the smartest move to just post a pic an ask "what is it?" without providing a little background info. And that one thing is prolly why any reply has taken this long. It helps to hear about where you got it. Did you pluck it from the ground? Or chip it loose from an outcrop or from a pocket exposed in an outcrop? Did your aunty give it to you?
Or did you find it in your neighbors garden? Did you bother to try an do a couple simple tests? For example: Streak, hardness, fluorescence, or specific gravity?
Sorry fer the verbal spanking but it would really help ifn there was just a little background info. Ok With all that bein said, from just a photo an a "what is it?"
It looks like malachite, if this helps.

Sorry Rock Hunter I literally had no idea what to put in the description. This was my first time finding something like this.
I appreciate the feedback and I will look into those things such as streak, hardness, and such.
I apologize for not giving much information but literally that was all the knowledge I know about minerals it's heavy and rough, lol.
I found it at an abandon house, that I'm helping to clean out.

Not sure but it appears to me to be a ball mass of Kimberlite heavy in Olivine!

A streak test will help. Green enough to be a malachite though.

 

[ZachSS]

I looked up how to do a streak test, but I don't have a clue where to buy the materials needed to do one.
Otherwise I would do one for you guys.

The bottom of a toilet tank lid works for streak test. Hardness can be ball parked by seeing what will scratch it . A fingernail is about 2-3, a copper penny is about 3-4, glass or knife 6-7. Specific gravity is a bit harder unless your handy. I've built mine that uses a small gram scale.
While I haven't been involved with rocks any where as long as some of these people here I do find IDing from a picture is often difficult.

 

[ZachSS]

Here's a picture of its weight and size comparison, I'll try what you suggested with the scratch test.

 

[ZachSS]

Here's a picture of a piece the broke off, it's kind of brittle.

 

[ZachSS]

I hope this is what you meant by a scratch test, thanks again everyone for the help.

 

[hvacker]

Ya Zach, that's it.

Malachite maybe

What colour is that? (that's a streak test you did there, by the way)

It was a grayish color and awesome, now I can do one. Lol

 

[Eu_citzen]

I think you are better off taking it to someone in person. A geologist or even a rock club.

Are you sure it's not petrified Sasquatch scat?
