Nothing of any real quality, hit up the blue nile in the city if you're looking for some serious glass
Well where in north jersey are you talking about? Do you mean around Bergen County or even more like Sussex County? I know a sweet one in Middletown, NY which is like 30 minutes from some parts of Sussex County.
if your not far from the city then i suggest going there to find some quality glass, i havent heard of any good shops in north jersey. Check out st. marks place, theres a ton of different shops, you can find almost watever you want, a lot of selection down there.
