Unknown Vase, Murano?

I can't find another vase like this anywhere, has anyone seen one like it? It is an unusual yellow/green colour, 7" tall with a rough snapped pontil mark, I'm guessing a Murano maker. The decoration is made up of what appear to be very small green murrines. A flower and stem has then been engraved around each one using an electric engraving tool. It doesn't photograph well, I will try to improve on them.
