Round brass box waiting on an idea

The first picture is a side view of the box, about 40mm diameter, showing the domed top and base, and the two filigree bands round the sides (the colours are my mobile's hilarious attempt at colour balancing, coupled with reflections). The second picture shows the top view, and the 1.5mm brass wire filigree decoration of spirals. I made the box of brass because I was tired of the rapid tarnishing of gilding metal. Polishing of the top using a conventional mop on a polishing motor was problematic, and I regard it as an unsolved problem for another day. Oh, and the idea the box is waiting on is 'what to do about the domed base?'. I made a domed base on a whim, and now somewhat regret it. In the photo, it is shown resting on the usual inverted saucer with a central hole, which turns it into a sort of lidded goblet.
