Hello can anyone tell me what this is? If I was to breàk it in half it is 100% the shinest metal I've ever seen. The outside Is covered in a thick calcite type crust. Thanks those are 2 different nuggets
I'm not sure, but if it breaks it will be some kind of mineral.
It resembles among other things arsenic mineral, be careful.
Where in the world did it originate?
What is its specific gravity and so on.
Not enough information to determine more.
