Is it magnetic? Radioactive? Fluorescent?
I had a mineralogy professor that was notorious for giving lab practicals that would consist of wonky specimens of similar/exact same colors. So ID from physical appearance was not a good option. You had to rely on all the other properties for identification.
Yeah, it's always best to examine a sample in all the ways you can. Especially radioactivity.
