Hello Leni - attractive glasses, although regret haven't a clue as to their origin - and as you're using the word uranium, I assume the bowls do glow.
Decoration on the flat tops of largish diamonds was commonly in the form of fine crosshatching, giving rise to the name strawberry diamonds - although with yours I think they are described as 'small stars inside diamonds'. As to the deeper cutting above, I's suggest that 'vertical pointed mitres' is adequate - it's a form of decoration on one of the common C20 Webb Corbett patterns (can be seen in the Crystal C5 archives).
As to the saw-tooth notching, this has been around on drinking glasses and decanters since c. 1850 - nice touch - and again the 24 point star is an historical thing which apparently started life c. 1830 - 40.
As to pointers re age - it's back to the usual culprits i.e. wear - stones - foot to rim ratio - cutting blip on the rim - striations on top half of bowl and foot - type of pontil mark (or none)
Having said all that I'd suggest IMHO that yours are C20, and possibly Continental rather than British, in view of the uranium. Assume they didn't come with any indication of age/provenance/attribution. Sorry can't really be of any help - but they are attractive
