A couple of Coro brooches I'm hoping to get a date on

I'm trying to date these two Coro brooches. I've looked over a couple of different sites but haven't really been able to some up with anything...Looking at the construction and color / design I'd say two different periods but not sure which. The script also appears to be slightly different between the two. TIA for any help!

 

This is an excellent site for Coro marks.

You're right It is. Unfortunately not complete. The brooch with the pearls is there (script-wise) but no date is attributed...(There's a facebook page dedicated to coro as well, but no reply yet)

 

Style on both looks sixties, fwiw.

 

Here is another good site:

I would guess (JMHO), possible early 50s, after mid 50s I would expect to see a circle C or circle R with the logo.

 

Yeah, I was leaning to the 40's or 50's for the one with the "pearls" but I'm thinking the other might be earlier, in part because of construction and "stones" used. I was kind of under the impression certain stones were more en voque at certain periods...
I'd like to see a more complete list of the various scripts used and the associated years
