Not a meteorite at all. Looks like a conglomerate stone.

Welcome from Texas :wave:

Great I.D. Hunter. :thumbsup:

"Conglomerate is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts.
A conglomerate typically contains a matrix of finer grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts."

If you believe your item is a meteorite, please take it to a professional or institution that specializes in meteorites. Pay the fee. Get a professional opinion.

That said, I do not believe it is a meteorite. My opinion is similar to others already given. Conglomerate.

Time for more coffee.

is this a meteorite?

Found this today kind of looks like possibly a Chromite meteorite but not sure so hoping some one could help. Browsed some pictures of
small Chromite meteorites on google images and seen some similar.
Not magnetic

I’d go for a dirty, porous basalt. Closer examination may change my opinion, but it is NOT a meteorite.

Here are a few informative articles talking about meteorites...

Meteorites are pieces of asteroids and other bodies like the moon and Mars that travel through space and fall to the earth...

Do You Think You May Have Found a Meteorite?

Portland State University - Meteorite identification
The mission of our laboratory is to conduct meteorite research to help understand our place in the universe...

About Meteorites

Aerolite Meteorites

A meteorite is a piece of iron, stone, or stony-iron composite that has fallen to Earth from outer space...

I thought it was a conglomerate rock too. What changed my mind was I looked more closely at clasts that make a conglomerate. I noticed they're not clasts at all. Clasts are fragments, these are spheres. I pointed out some in this picture which you can clearly see the material in each sphere go around. Since they were formed in space. Which is what a chondrule is. I appreciate your guys's help, thanks.IMG_20210408_222355.jpgIMG_20210408_222112.jpg

Hi ‘Fun hunting’ and welcome to Tnet.

Those are not chondrules, and your specimen is not a meteorite. It’s possible for a meteorite to be non-magnetic but, if it has chondrules, it would need to be carbonaceous (for which your specimen is completely the wrong colour) or from the very low metal group. Low metal chondrites usually exhibit some weak magnetism until you get to the LL group (which is relatively rare) but LL chondrites are the most homogeneous of the chondrite group and the chondrules invariably have poorly defined boundaries, making them difficult to discern. Quite unlike your specimen.

Your understanding of what a ‘clast’ is needs some clarification. A clast is indeed a fragment of rock which has a different composition to the matrix surrounding it but the geological definition does not imply that ‘fragment’ = ‘angular’.

Clastic rocks which have angular fragments are called ‘breccias’ and those with rounded or sub-rounded fragments are called ‘conglomerates’. It’s the amount of rounding which distinguishes the two types and conglomerates can have spherical clasts. The rounding of clasts in conglomerates is from weathering and/or water-rolling, producing clasts than can be any size from sand to boulders. The precise geological definition is that they should be larger than 2mm and comprise at least 30% of the overall composition.

Conglomerates are also subject to sedimentary ‘sorting’ such that the size of the clasts can be relatively uniform if well-sorted or a mixture of sizes if poorly-sorted. They’re also classified by composition of the clasts. When the clasts are all of the same rock type they’re called ‘monomict’ and when they have two or more different compositions they’re called ‘polymict’. Your rock is a relatively well-sorted polymict conglomerate (and terrestrial not meteoritic).

Agree. Conglomerate rock. Meteoric chondrules are not held together in a sedimentary matrix. That rock of yours is water current rounded quartz pebbles formed into a sedimentary rock - in my non-professional opinion.

is this a meteorite? diamond?

I found this today, what could it be? the interior is bright.

Ersbel, there is no need to double post. Your answer is on the other thread on this item.

Time for more coffee.
