That evaluation is a good start, as far as critical thinking goes. The description you give, however, also describes a great number of terrestrial rocks, particularly metamorphic.
If you have interest in learning about meteorites, please get a few good guides. I would refrain from web sites and YouTube as a source of information, at least for a while. There are way too many amateurs out there who do not know what they are talking about. If you follow this section of the forum long enough, you will see what I mean.
For the matter at hand, ask a qualified professional to take a peek. Some geologists will be able to give you a qualified opinion, some won't, so you will have to do a little homework on who to take it to.
An iced breve just appeared in front of me. Time to take it outside.
