I have seen something a bit similar - it was flat clear glass plates, with bobbles around the edges, on a similarly fancy brass stand, but it had several several tiers of ascending sizes (from bottom to top) - possibly for little fancy cakes.
Bobbly edges are things I tend to suspect of being German or possibly even Czech origins. The former, possibly because of a large exposure to lots of contemporary Walther stuff in charity shops and the latter, because of a couple of finds with bobbles on the surface of the glass, one, a jam thingy has Czechoslovakia moulded into the base, the other a big mystery in pressed Uranium glass with some age and no id yet - Czech is suspected.
Maybe Ivo had a grand piano?

(But don't they just have 3 feet?)
