Yes I'd been looking up Rubina just in case.
I'll do some more searching.
I thought I'd achieved a good colour representation but just to clarify there is no amethyst in this at all. It really is all bright bright fuchsia pink.
However the camera is picking up a darker shade as a fine line around the rim. (I've attached the pontil picture again where I think it can be seen). So I've held it up to bright daylight at a window and I think there is a very fine very thin darker almost red line around the rim. I wonder if it has been finely cased without it showing really on the fade. That said, Webb Alexandrite has a dark fine line (chocolate) around the rim so the fact this has a darker fine rim doesn't definitively mean it was cased rather than heat-treated.
I understand your question about whether it is an 'off clear' or an 'off amber'. I had exactly that question in my head
Having looked at lots of rubina (not rubina verde) glass it appears absolutely clear on the clear part and I think this is an 'off amber'.
The base glass at the bottom is definitely peachy and not clear. I just wonder if this is because it's been reheated and because it has colloidal gold in the mix? Just pondering on how the maker would have achieved a bright fuchsia pink without it being colloidal glass and reheated. I think that's the only way probably but I am certainly no chemist and neither a glassmaker so that's just my thoughts.
I really don't think it's Bohemian glass. I think it's likely to be English or American but never say never (bought in the UK). I am also completely sure it is old glass and I think lead glass. So it's come from a good maker but who is the question
