I have seen very similar paperweights with the sticker attributing this to Malta. Although this doesn't have the sticker I'm confident that this is the same. Gorgeous paperweight with a lot of depth with the layer of color underneath a clear glass layer. There is a wavy reflection (see pictures) but seems to be a manufacturing effect that reflects back but not a crack or chip. There are 2 dings see last picture, these are very small bit I wanted to point them out nonetheless
