I've had this vase for a few years. It's confusing because the internet tells me nothing about it, and there's no "Jema" on the search engine here.
The label says "Jema Glasbruk Boda Sweden" and it's signed on the base "A Gray '96". It stands just over 8" tall.
I have another one, which is white with the same blue rim but a bit more bizarre.
All info appreciated,
