Victorian cased glass vase with thorn handle

This Victorian glass vase is made from two layers of cased glass - a shaded yellow over a white interior. It measures 16.3 cm tall. The vase has an applied thorn handle in amber glass, & a tightly crimped top rim. Base has a rough, snapped pontil mark. I have seen this type of item attributed to Stevens & Williams, but I think this example is Bohemian.
