No, these are not pearls, unfortunately. They are just beads.

I agree with @jshepherd
Those look like Hematite beads to me...and if they are not hematite, then maybe glass...but NOT pearls at all.

They look like Swarovski glass "black pearls". In quotes, because they're glass, and not real pearls. I had some once, before I learned what real pearls looked like.

Likely hematite. That would be gritty.
Not pearls.

I found the easiest way to "test" pearls is to gently rub 2 pearls from the strand together, if they feel a little like sand paper, they are pearls, if super smooth = something else. The amount of sand paper feel with vary, but never smooth and slick.
