That's cool , looks to dark for magnetite so I am saying asteroid :Y: someone who knows more may disagree but I like the look of it.

This is where you need to do what Gotham City does with Batman, and appeal to goldierocks for help.
P.S- I forgot to mention, as I notice you are new to the forum. Goldierocks is a geologist who is one of our members and knows his stuff :Y:
The surface looks somewhat like a meteoritic fusion crust, although the rock appears to be a bit too smoothly rounded and uniform to me. However, my understanding is that meteorites with a fusion crust aren't magnetic and that only iron meteorites respond to a magnet.
Unfortunately, iron meteorites are typically highly irregular in their shape and surface texture and look nothing like the rock in the pic:

Good Evening All,
Appreciate your feedback. If it helps rule some options out, I found this specimen gardening without my detector (Garret ace 300i) I then ran the detector over it with no detection registered. Just to be sure I also tested all predetermined settings - nothing.
Also, appreciate the heads up regarding Goldierocks as the go-to expert!
Due to size, Ive attached additional pics.

It looks interestingly aboriginal, milling, pounding or hammering. Basalt is my guess, but depending on your location it may have been transported quite some distance. Indigenous people used natural-preformed stone tools and modified them for use if necessary, and this one looks definitely like a waterworn stone.
Can you provide a picture with it next to something to give us scale of size?

His very first pic above shows it held between his fingertips and it's pretty tiny, perhaps 20-25mm long.

20 - 25 mm ? Ignore my input then. Still, is a nice little rock.
11mm is my guess
LOL
Looks like I need "Specsavers"
Lucky I'm not the only one....
I was looking at a meteorite a few weeks ago, two of them, they were not as smooth as that, and definitely responded to a nox 800.
One about that size and another 4-5x bigger
Both showed heat indicators and were very heavy.
But there are many types.

Good Evening,
Found this specimen this evening about 0.5km from the first. Magnetic, heavy for its size and metallic finish. Any feedback you can share would be greatly appreciated?
Without the camera flash similar colour to first, but for some the reason the flash made it appear slightly orange.

I found this meteorite on 15th September 2021 North of Meekatharra. It consists of five pieces, all found within a one square meter area and have a total weight of over 7kg.
The WA Museum is classifying it and think it may be part of an already reported/documented find from 12km away. It apparently is a L4/L5 chondrite and consists of mainly silicates with iron/nickel specks through it.
They gave a hell of a signal on my GPX4500 and all five pieces were sitting right on top of the ground.
If you are out doing a lot of detecting, there are sites you can Google which give you a good idea of how to field identify meteorites. Most are magnetic to some degree but there are also some that aren't.
Top photo is one piece of the five
bottom photo is a slice showing the iron/nickel flecks

Toadskin, amazing specimen, thanks for sharing!
Heres another specimen found 20 metres from the last, this part of the oval has different soil which is mainly sand, Im no geologist but guessing part of the crust formed when it landed. Also magnetic and heavier than normal. To help substantiate the nature of my find, I sliced it with angle grinder. Feedback most welcome...

When I see something like this, bent up like plasticine, it immediately says MOLTEN. My first reaction is that its a TEKTITE. There are two theories on Tektites - 1. They are formed when a meteor smashes into the earth with great heat and force the surrounding rocks etc to shoot up into the air and slow down near the edge of space at which point they drop back to earth - not to the impact site but further along. As you know, the planet is turning at 1,000 mph at the equator so while the affected rocks are travelling up then down, the planet has moved on. (I learnt at school that the Equator is 24,000 miles in length, and Speed = Distance divided by Time so the Earth is turning at 1,000mph(24,000 divided by 24) This is why I'm using mph and not kph - its easier to understand!) That's the first and popular theory.
The second theory is that the they are formed on the MOON - Yes, the MOON!
Meteors are belting into the MOON all the time and because they don't have a thick atmosphere to slow them down they form sometimes, huge craters. The rocks
blown out by the the explosions head out in all directions but interestingly they are not found all over world and the ones that hit Australia are only found in specific areas. It would seem that they are found below the flight pattern of the MOON as it orbits the Earth.
The main proponents of this theory are a group of NASA scientists. GOOGLE -" Tektites Lunar Origin -NASA Scientists " and you'll get all the detail. There are a lot of arguments around the scientific community for and against.
Me - I'm all for the MOON as the origin of your specimen. How many people have a rock specimen from the MOON?!!!

Hi George B. Perhaps if you could carry out some basic tests that would be helpful. The bit that is sliced seems to show metallic content. Does it react with hydrochloride acid?
Can it be scratched with quartz, a nail or a pocket knife? Are you able to do a specific gravity test on it to determine its density?
Looks Tektitish but these glassy objects are formed from impacted melted surface rocks and are usually poor in metal and give no detecting or magnetic signature.
Just from looking I’d have a stab at meteoric iron. The scatter of the objects also seems to be consistent with a meteoric fall. If it is a great find!
