Aaah, but perhaps they are not American, Lissa.
The colour is an unusual shade, even for Jade glass - (I'm currently learning about different types of uranium-containing glass) and it does remind me a good bit of a colour that is specific to Stevens and Williams - is it very
slightly "see-through"?
Normally, Jade glass would be completely opaque, but I have seen a few bits (not many) of this shade of green which is slightly see-through - and they've been Stevens and Williams. My worry is that all the few bits I've seen are all hot-worked glass - so your bowl would fit with that - but your goblet (or "candy jar minus a lid") looks like pressed glass.
Quite often you can see the "glow" just in a bit of sunshine - (if you ever get any

).
We need to wait and see what others might say.
Lustrousstone, we need you!
