This almost cube shaped size 11.78mm x 12.0mm has a shiny sheen silver-grey color over what looks to be a reddish host.
Any and all thoughts welcome to what it could be...Thanks in advance to all...
Might be a piece of weathered Arsenopyrite. Kinda small but you could try a scratch test and sniff the result. Arsenopyrite is said to put out a sulfur smell when struck and scratching is pretty much the same thing.
