Girls, Ladies, how do I move things forward with a girl that has already shown a subtle interest in me in a way that doesn’t ruin it?

There is a girl in my biology class that I am interested in. She already complimented my rings and is friendly towards me without me having to initiate, so it seems like she is interested in me too. Now it seems like she’s waiting for more action on my end. I’m wondering the best way to move things forward that doesn’t seem weird or deflates the romantic tension. I also have to sit by her for the rest of the semester so I don’t want to make shit awkward. She said something about her own rings meaning something spiritual. This already shows me we might have a lot in common, so I am pretty invested in this going well, which is leading to some overthinking probably. Gimme some feedback
