Meteorite or Meteowrong ???

[Farmer1974]

I found this while plowing a garden. It has a heavier denser feel than a normal rock, I did a Google picture search, and it pulled up meteorite matches. After doing more searches on the internet, I found some tests to do. The first test was on unglazed porcelain to see if it would leave a mark
the item left a black strike. I also read that a weathered meteorite would leave a mark.
The item doesn't seem like it has any magnetic properties, the Magnet doesn't seem to be attracted to it. I read that there are some stony meteorites without metal.
Would like to get some opinions if this could be a meteorite.
Thanks for any help

What state are you in?
to me, it looks like hematite.

Welcome to Tnet.

I don’t think it’s a meteorite. From the surface appearance, if it were, I would expect it to be in a classification that has enough native iron to exhibit at least some attraction to a magnet (ie not an achondrite or carbonaceous chondrite).

It appears to be a terrestrial nodule of some kind but, if it truly streaks black, it won’t be hematite or hematite-rich. Hematite streaks reddish-brown through to blood-red. Hematite and magnetite frequently occur together and magnetite streaks dark grey, approaching black, but if there is enough magnetite to produce such a streak then the rock will exhibit magnetic attraction (hematite itself is not attracted to a magnet and only has that property when magnetite is present as a secondary mineral).

Pyrite (also not attracted to a magnet) will produce a black streak, but usually with a greenish tinge. It doesn’t look pyrite-rich though.

Meteorites generally do not produce a streak and will usually skid off the surface of the tile. At best there might be a weak dirty greyish streak if you press really hard, or if the meteorite is weathered.

Terrestrial igneous rocks (basalts etc) will not produce a streak.

Might I ask exactly how you performed the streak test, since there are two common mistakes that people often make when testing. The correct procedure is to streak firmly once or twice (and separately if making multiple streaks) and then blow away any dust. It’s the colour of the underlaying streak itself that needs to be examined, not the dust created. Also, rubbing to-and-fro as if you were colouring in can give a misleading result since the dust created can be forced into the ceramic tile and be mistaken for the actual streak.

We found a porcelain shelf sitter with an unglazed bottom. We pulled the rock across the bottom as you would write with a pencil, an about the same pressure. The 5 lines in center are from rock. The outer edge is black paint from the shelf sitter.
We also did a specific gravity test today, using the method of a cup on a scale and lowered the rock in the water with dental floss.
The Rock is 79g and 17g with rock lowered in water
that gives a 4.64 density if my division math is correct.
