geologist

Looking for opinions on this one! I’d say it’s a little greener In person than in the photos. It’s also slightly magnetic and dense for its size. Maybe a more seasoned rockhound or geologist may have some input!

I’m clueless and hoping someone can help me identify this rock/mineral.

I recently bought this crystal and was wondering if it is smokey quartz and a good quality crystal. Any help is greatly appreciated. Thank You!!
