Is this a query - or a test?

Is the neck really how it appears? To be a conical amber shape, inside a clear, straight "funnel".
We have a small general clue/lead to follow, with the use of gold foil.
But a lot of folk have used gold foil.

So one has to consider the design too. Modernist, probably
fairly recent.
It's small, but with that neck, a complex piece - it's hard to
make something small and complex. Requiring experience as well as talent. I am wondering about our Adam A.
