Well, there is a hint of the late 19th C. in the shape actually, but the colour scheme suggests a later date to me, which is why I suggested a date of 1920s. Victorian glass did not typically have this type of harsh contrast between colours. Victorian fancy glass was colourful, no doubt about that, but it was more likely to use tints, eg, pink, lime green, peach, pale lemon, rather than pure primary colours. This combination of yellow (or orange) with cobalt blue was a popular one in the 1920s-30s era.
I don't proclaim to be an expert, & nor do I sell glass but I have been collecting it, & reading about it for a long time & I think I've developed a "feel" for it. Shape & colour can tell you a lot.
So, it's a sort of late Victorian shape with a 20s colour combo.
Hope this clears up any ambiguity about my attribution.
