The Mdina vase shown by Tiger is not like the vase in question, although the colours are similar. Whatever it is, I think it's newer than the areas I'm familiar with in Maltese glass. It might be Isle of Wight, as I know they did a swirly ribbony pattern like this pink bit, also on a surface decorated finish - a design I believe to be called "Topaz".
The shape of this vase is more IoWSG than Mdina.
However, I know of a contemporary glassmaker, Steven Foster, who uses a "snakeskin" effect, similar
to this. There may be many more.
