Found this small black/grey rock in situ and it attracts very weakly a magnet.  It weighs 23 grams and measures 3 x 1,5 x 1 cm. meteorite?

Have you ruled out the large number of terrestrial magnetic minerals which are vastly more likely?

 

Doesnt look like a meteorite. Does look like a piece of haematite or some other iron bearing mineral.

 

I suppose if you think its an iron meteorite you could slice it and etch with acid to reveal the Widmanstätten patterns.

Desert vanish basalt

Here is a video of myself comparing one of those basalt and a crusted authentic meteorite

oke, only one little problem. my stone is not a basalt. No visible crystals and it looks allot like hematite but it is something else. I have compared is with a weathered Nantan meteorite that i got as a present and it has the exact same texture. hard to see on the photo. here a better one.

Hmmmm

i have send pictures to the depot of natural history and the said it is not hematite because it has a black streak in stead of brown and it can not be magnetite because it is to weakly magnetic. The don´t know what is could be but it is a glacial erratic according the rounded shape.

You know, two weeks ago in Madrid, Spain, has been removed from display a foundry slag that was more than 150 years old exhibited in the National Museum of Natural Sciences as a meteorite.

That's what happens when we believe that anyone can tell the authenticity of a meteorite just because they work in a museum.

oke get the point, and this one is  probably also not a meteorite. Comes from a farmers field

are the stones around it all meteorites too?

[AnnaBoha]

It looks like slag but often slag is shiny like obsidian, but rougher.

 

The farmers field find looks like petrified mud. It might contain a fossil or two.

Can you measure the density and hardness of the rock?

Can you measure the density and hardness of the rock?

the deal fell through, couldn´t get the rock to my house i weight much heavier like 80 kilos

It's impossible to tell if it's a meteorite simply by looking at the outside.. You'd need to make a thin section and use a petrographic microscope.
