What type of bottle is this?

I'm not all that familiar with bottles. What type of bottle is this and how old? It stands about 10 1/2" tall with the stopper. I see one very light mold line that disappears near the top and it has bubbles, so I think it is a blown in mold. The stopper has two mold lines and has a snipped end. The bottle has a pontil bottom. It looks a bit "dimply" as well. The purple amethyst color has a subtle vertical striped pattern that goes the same way as the swirl on the neck. It feels delicate.

All comments welcome. Thank you!
