Is this rhodium?

[Joncarlton81]

A friend of mine found several slag looking rocks like the one on the left on my property and says the smaller specimen on the right came out of the middle of one . He thinks it's rhodium? It does have the mirror like shine but I don't know. Can someone tell me what they think it is?

Welcome.
Nobody can tell unless you test it.
And that can be expensive.
Most likely not anything precious.
