dear experts!
some time ago I bought a very interesting piece in an antique shop.
looks like a small cup. yellow amber glass or crystal. sound - sonorous. covered with enamel or ... I do not know what. blue color. seems that glows inside.
help to find out who could make it, and when.
I think it is - the antique and the bohemian.
What do you think?
6,5 inches in height with lid.
