it's obviously not very tall - I'd have suggested an open sugar, possibly, but the bowl shape looks a little too wide and possibly too shallow.
Yes - stones/inclusions/seeds, whatever you want to call them - although such things tend to be found on glass that would be older than this, usually. It's a little unusual, having the pressed bowl but with cutting on the foot.
Would have thought the odds are against you ever finding an attribution, unfortunately. I had looked through a few books, but no joy.
