I picked up an unusual vase yesterday at the boot sale and sat it on my desk while I searched the web trying to identify it. This evening I noticed that although it had started off the day a clear pinky violet colour, it had turned aqua as the lights got turned on. A bit of experimentation later and I think I have acquired my first piece of neodymium glass

So now I would like to know more about it. Does anyone know who it was made by, or when? It is quite Scandinavian in style I think.
The photos are a bit rushed and had to be taken without flash as the glass looked clear with a flash (?), so they are a bit dark.
