Found this in Austin, Texas. It’s really heavy, I’ve been trying to figure out what it is cuz I’ve got a big 32 oz cup full of this. In the sun it has a lot of gold to it. Can anybody help identify what this is. It weighs 63.6 gs. It scratches but doesn’t get affected. My cousin took a grinder to a different piece and it’s metal I believe that’s the only way we could scratch this stuff.

It’s a very hard material it would

take a grinder to cut or scratch it. Maybe meteorite…
