Not a meteorite but a Kimberlite. The texture of the stone and the presence of feldspar and what are either chromium diopside or pyrope garnet, the green gemmy crystals, are typical for kimberlite. A source of diamonds you may want to go back to where you found it and check around Good diopside or pyrope garnet are worth a penny as well. Nice specimen and thanks for the cut view.
Thank you Terry. My guess is slag. And just curious, but does everybody have a Kimberlite pipe in their back yard? They are way more rare than meteorites. And meteorites are ridiculously rare.
Actually, meteorites are not rare, they are just hard to find. Regarding kimberlite pipes, you would wasting your time looking for. BUT, there are good chances you could
locate lamproite pipes. I discovered a small swarm of possible lamproite pipes and a possible meteorite impact crater in my back yard. (Don't define 'back yard' by city terms. My back yard is pretty big.) One can be seen out my window, the other is just down the road. Diamondiferous pipes are usually found by locating 'indicator'
minerals. I could not do that so I used my hand-held rock crusher and microscope to look for diamonds in the crushed rock. I eventually found one microscopic diamond
(GIA jeweler verified).
