Yes, I agree about lampwork being exciting and very beautiful too sometimes. I do a fair bit of beading and use a lot of lampwork beads. It amazes me the amount of detail that can go into them, and it always seems a shame that they are just hanging from a bracelet, necklace etc as you have to see them close up to really appreciate them.
I am posting one last picture. I DO think this is quite beautiful, it just makes an ugly ring. My mum agrees! I would have thought that whoever made this would have made the band round rather than U shaped. This photo gives a better idea of why it seems an unlikely ring, unless it is just not very well made . . .
