Richelieu faux pearl earrings question.

Hi all,
I recently purchased these and was wondering if someone could tell me if the earrings were actually Richelieu. they came with the choker but are not signed. only marked sterling.
I couldn't find anything on them till i came across this 1945 ad which clearly shows the earrings. or similar to mine.

And the earrings have no identifying marks at all? They do look like the ones in the ad. If you purchased them with the necklace it seems likely that they have always been together. Unless some previous owner tracked down duplicates.

 

Nothing but 925. Thanks fig...
