How late are the jewelry kiosks open?

When the mall closes.

I can't say conclusively, but when I had a kiosk it was a requirement to be open during all mall hours. I doubt that has changed.

I am so sorry I do not live in NEW Hampshire, I only went once to visit a friend and she took us to the mall.

I believe 9 pm

Probably about 6 or 7 at night, when the mall itself closes. Not necessarily when the larger stores close.

I don't know when jewelry kiosks close, sorry
