Rock/mineral identification please help

[Patt]

Hi all, found this little rock in the bottom of the pan, even panning slightly aggressively it would stay in the bottom with the small gold I was getting, just wondering if someone could help me out with what it might be. Opaque dark gun metal grey colour, Found in northeast Vic, granite creeks,I think volcanic geology aswell, havnt found any gems there before. Hope that helps
Thanks

Is it magnetic or does light pass through it with a torch?

Was just reading some of your older post about granite . It's non magnetic and light doesn't pass through it....

Could be Wolfram. My granddad found a big chunk of it up near Yack many years ago and I believe that there is more of it around.

It looks similar except this has a more flat colour, kind of like slag when welding

Retirement Stone nailed it, it's most likely black Spinel.

How to do a specific gravity test should be a sticky on this thread . I'll add some other identification info when have some time ...

I'll get onto that Barney, I might just make it a stone identification sticky thread, what do you think? Then you can just add what you think are the best tests that people can perform at home?
