I would agree that both the headdress ornament and the 'eyeliner' place this as 'Egyptian' in the loosest sense. If you go to Egypt, you will see all kinds of moulded, carved and moulded-embellished-with-carving pieces representing everything from Pharaohs and Cleopatra to Anubis and sacred cats sold at markets... plus generic figures of no particular assignation. And in every material you can think of, including glass. They're sold as ornaments, paperweights or pseudo-relics and have been around since the 1800s.
I would think this (which is likely a broken part of something larger) falls into that category and is probably vintage or perhaps even antique, but not Dynastic. When I blow up the picture I can see numerous areas which exhibit the tell-tale signs of having been ground with modern rotary tools.
