mineral id help

What is this mineral please, it looks like it has an oily surface?

Not sure what the actual mineral is, but the colored sheen is 'iridescence'. I have some rainbow hematite with the same effect.

Hi this is silicon carbide aka carborundum. Looks like a nice specimen 😀

The iridescence looks cool on the larger planes

thanks all. i've located the mineral in the app too 😀
