Two cameos

Hello everyone!

Two beloved family members gave me two beautiful cameos.
I don't have much information about them, except that they should both date from around the 1950s-1960s. I also think they both come from Italy.
The one on the left (#1) has a roll-over clasp ; the metal frame is not marked.
The one on the right (#2) has a simple C catch (or, maybe, what remains of a roll-over clasp) ; the frame is marked 750.
What other information do their details convey?

Thank you very much, as always!

 

@Bronwen .............. calling our cameo gal..........to...make a Cameo !!!!!!

 

What you already know is correct & most of what there is to tell. The 750 mark indicates 18K gold. The cameos are hand cut helmet shell. The ladies are not anyone in particular. The one with the comb & veil (I know I'll be corrected if I call it a mantilla) is a type that was a fad with carvers for a time. Nice to have these handed down to you.

 

Thank you very much @komokwa and @Bronwen!
They are very lovely indeed
