Different pics might help, I think I'm seeing a lot of reflections
Smaller one obviously looks like guinea, what color is the base glass? Seam looks tighter than what you'd normally see on bullet mold (and most contemporaries). but the base glass is throwing a curve.
Is that a pontil on 2nd one? (first pic)? pattern looks abstract enough, could be contemporary.
3rd looks like Veliliglass to me
