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

I found this sucker rock hounding a couple years back. It's slightly magnetic and weighs 1lb. 9.6 oz. It fits the description of what I've read to be a stony meteorite or fusion crust? It looks like a miniature version of the Hoba meteorite. Same texture on the top as the Hoba. It has what appears under a loupe to be encrusted with tiny diamonds, gold speckles, and silver/ platinum in one little area.
What do you fellers think? (the giant one of course is the Hoba)

What kind of Stone did I find- It was in a muddy area just off road- I was searching for garnet but was in the wrong area-

Doesn't seem to streak-

its clear, with may fractures-

maybe from a larger stone I didn't see- View attachment 1419022 View attachment 1419023 View attachment 1419024 View attachment 1419025 View attachment 1419026 View attachment 1419027

Possibly quartz. A hardness test with quartz will confirm, about same hardness = no scratch.
Try it and get back to us.

Do a streak test (= Rubb against a unglazed piece of porcelain) and get back on what color you get.
Also see if it can be scratched by a knife. I'm betting it's of terrestrial origin.

Thank you sir. I will do that (later on next week when I go into town). I gotta get a piece of porcelain. I tried to scratch it with a knife, using some decent pressure, and it leaves a small mark that I can wipe off with my finger, which removes the mark completely. Is that an indicator of a possible piece of fusion crust/ meteorite? Thanks in advance!

Ok I finally took some pics of some stones that I am trying to identify as diamonds HAHAHAHA!! I mean, I do not think they are quartz but I'm also an optimist LOL! The big one that is kinda long, is the one that actually came from Crater of Diamond State Park in Arkansas.

There is one part where you can see a bit of a rainbow color but otherwise it is clear (just dirty I think...).

The underside of the lid on your toilet reservoir should suffice for your streak test.

Great idea, thanks. Unfortunately, what I just did in that room won't enable me to do that until tomorrow.(damned Fiber One bars)

You've got a one in a hundred million shot of it being a meteorite, and a 1 in 1 shot of it being slag from a metal operation of some kind.

 

[FFFPatriot]

I'm gonna take it to the geology lab at the School of Mines in Butte this spring. I'm still gonna hold on to the (probably a false hope) that it's a meteorite. I did think that it could be a hunk of slag, but that 1% of me doesn't want to believe it.

Can you tell me what kind of rock this is?

I found several of this rocks in Arizona. They were a vein in the side of red dirt or clay hill that looked like it was a river bed. This pictures are of the thicker ones. Found some that are darker in color and some that are lighter.

Could that be red calcite? It is really cool looking!!!

Fusion crust looks quite different to yours, its a surface phenomena; Notice your rock is the same color all the way through.
I assume it left a metallic mark then, from the knife.

Slag is a candidate, the weak magnetism is due to traces of iron left in there. Seems not to be a meteorite, I'm afraid.

Use a knife to try and scratch one of the milky-looking fellows to the right of the turquoise paper.
If it leaves a metallic mark (= harder then knife), likely quartz, as most of them seem to be. Don't be afraid to use a little force, if needed.

Magnification is useful for the newbie doing this test.
A 10x loupe is what I'd use (get one, basic tools of the trade!), but a magnifying glass can do in emergency situations.

When we have ID'd one as quartz, use it for further scratch tests as diamond is harder then quartz & will scratch it.

On the 6th image, use the bottom left pieces, to do the test with quartz as described above.
Quartz tends to be less "shiny" then diamond, another indicator to use as to what pieces to test.

The rock seems wet. Give me a couple of dry pics, the wet surface hides the luster of the rock, making ID harder.
Also see if a knife can scratch it.

Ok thanks! I don't think I'll get the loupe in the mail before I leave next Monday, though I'm going to order it in a minute...and will be gone nearly a month so I'll post when I get back what I find out!

A rock found from deep underground. It has crystles in the inside.

Thanks, my friend. I'm with you, after seeing some pictures of slag, I believe you are absolutely right!

Milky-Green Quartz-like rock

The first is with flash on and is a decent rep but the transparency is milky closer to the top and bottom and is clear in the middle. Is this an algae or natural colorization? I tried the bleach suggestion to remove possible algae...no change. It doesn't appear vivid enough to be emerald and darker than most peridot I have seen. It was originally found on a white quarts chuck that I found hiking in the woods. I assume another layer of quartz was on the other half due to the same marks after this broke off the main chunk. It is brittle, this piece here just broke in half when it fell on the floor...what is it?

This is my first post so hi everyone! I recently got a metal detector & came here to learn but was pretty happy to see this thread also. Just wondering if this game was still going. ��

Has a sedimentary look to it. Will a knife scratch the off white portion? Will it react with vinegar?
