Like a water world with tiny golden islands on an ultramarine sea.
I have a few paperweights but this is my favourite. I look into it and am enchanted by how they managed to embed gold leaf into it. They must have gathered the blue glass and rippled on the black layer, then put gold leaf on and blown into the glass to make it split up or maybe just let loose gold leaf fall onto it? Then gathered (added a layer) of clear glass on top.
I’m only guessing about the technique but however it was done, it’s beautiful.
