I can't see enough detail, but I really do not think so.

The blues used did vary, but the handle there is far
too kingfishery blue. I can't make out the texture in the glass itself, but it doen't look right from what I can see.
The pontil scar is wrong, but on this sort of item, might have been weird, but that isn't a kind of scar I have ever seen on Mdina or any other Maltese glass.
