I 'think' this is right.... but I can't find something to compare it to and it is different to my lidded powder box despite being a very similar decor.
It's mould blown, cut polished and bevelled rim, the black is very dark purple when held up to the light, the coloured decoration goes under the base but is on one side only of the vase, it doesn't feel as heavy as my box, which is completely opaque even held up to the light. Measures 19cm tall.
What thoughts?
