Got A Rock you Want Identified? Post it here! gimme a good picture or 3 or 4!

This isn't so much about the rock, rather the silvery/pale silver stuff in and on it. I do not think it is mics, but I could very well be wrong. Hopefully you may be able to tell me more..Thanks in advance.

A sulphide seems likely.

Im not sure if the pictures are showing up but they are clear and crystal like. I found them while panning in the snake river in idaho.

Small things can be tricky. Perhaps quartz?

Your failure is due to you using the wrong methods. No hydroxide is used for mineral ID work, it will at best be used to check for gold in sulphides.
Do a hardness test, streak test for starters.

Cheers. I did a streak but just silver so don't know what to make of that.Hardness.Yeah.Did that.Also the density is coming out at about 2.4 but it is full of bits of rock.The mineral inclusions are consistent. I was trying a hydroxide cos of something I read about identifying metals by their precipitates. But just like the streak test and density and peroxide and hardness. Still leaves me unconfident that it is silver.But I am confident they are natural cos of consistent inclusions. Just natural what? at the moment. I hope they are not silver actually. But I am confident they are natural. If they were natural "something else",they would no doubt be rather rare.Whatever they are. The tiny purple gems in the stones in the nuggets of metal make me quite sure they are natural. Just expect silver to be heavier.Even with rock through it. I have tried to find out what silver metals form nuggets naturally. The closest I can come up with is silver. Closer to strontium or aluminium in density.So who knows.
Thanks anyway

Can you tell me what this is? The story goes my Grandfather found this ?cats-eye? stone on a beach during WWII somewhere he was stationed. On the back is a picture of him in his sailor suit and the silver holding it all together is a nickel he hammered out. I was told he made this for my grandmother. Any information on this stone would be greatly appreciated. Hope I'm posting this in the right place.

You feed your results into this to find possible IDs, then try to weed out the more or less likely ones.
Takes experience and some common sense, yeah I've fooled myself more then once using it. The test results are quite case sensitive, so to speak.

Well I can tell you it's not cat's eye, which is chrysoberyl. But I won't be able to give you a proper ID on it either, you see we work mostly with rough stones here.
I can, however, point you to the right direction:
A gemologist might be helpful, whom can check it out in person.

Any chance you could ID this? Found it in Ontario, Canada. My daughter thinks it's a dinosaur egg fossil and I told her I'd post it to try and figure out what it actually is.
Thanks!

Found this on the beach in the San Juan Islands of Washington State. Kind of cool, I thought. Never seen anything like it on the beach before or since. Sorry, it has been tumbled.

Could be a concretion.

Looks like a quartz vein going through host rock.

Kimberlite? Background is concrete.

 

[Amye]

Found this inside a huge boulder that had cracked in the mountains of NC


My son chipped it out for me. I think the boulder was granite but I am not sure. The black part is (for lack of a better word) sparklie. It seems to have a white looking rim around the black part.

 

[TheOculus]

Amye, that looks like classic pegmatite from North Carolina. The black is likely Tourmaline and Biotite Mica, the white is likely Quartz & Feldspar; there could be Beryl and Garnets as well. What county did you find this in?

Here's a couple of pics of a rock I found near a gold bearing area. Is this what I need to look for to find gold. I know its got quartz but is this the type? Found d near creek on rocky outcrop cliff.

 

[Notarockman]

Hey guys, I know nothing about geology, so if you'd oblige an ignoramus. I found this amongst the ashes when clearing out the BBQ today any help would be appreciated?

Stone looks wet. Is it? Use a hammer, chip of an edge and show us the surface.
Chances are it's something more common then kimberlite.

Crush and pan, or have it assayed. Best to test!

Mica schist.
