Is there any age-related wear to the base? How it the pontil mark finished off?
Do you have the very close-up close-up setting on your camera? (The flower symbol with the "s" beside it)
I love the colours in the glass and the bubbles - but I cannot see the design/pattern in them clearly, to see how it was produced.
Looking at the silver work, which I can see far more clearly now, I am having a wonder if it might be contemporary, from Thailand. I've seen a lot of fabulous costume jewellery over the last few years, with beautiful "art nouveau" style silverwork around faux jewells and glass.
I've got a necklet, will post a pic.
