Need help to identify age and/or possible makers of rhinestone pins

[fair-vanity]

I have had these a while and never tried to sell them since I had no idea how old they were and who made them. None are signed! I was wondering if anyone here could tell me anything about any of them? Thanks so much!

The largest one (round) is 2.5" diameter. I show 2 pictures of the back to help with poosible ID.

Hello ! It's really hard to say who the maker is without the Maker's Mark . The larger , top left brooch does look high quality though . Any way you could post a close up of just this one's back ? I would say all of the others ( except for the one set on black ) look prong set and are probably from somewhere within the 1940's - 1950's and they are collectible . Maybe you could group them together and sell them in a lot . Might make it a little easier . The black one looks pasted and a little newer . You could throw it in the lot too . Wouldn't hurt . I really like the heart duo pins , too cute !

I think they are all high quality but I have enclosed a close up of the back of the large one. Also, I think the black one is the oldest one. I posted a close up of the back of that. The two small ones are not hearts though. I reposted the picture of that one, too. Thanks for your help!

Aha I see now the Duo is 3 sided . Looked different in the first picture . I guess it was the way it was laying . Very cute . Nothing about any of them screams any 1 designer , but they are a nice icy collection . I'm curious what makes you think the black one is the oldest ? Maybe I can learn something .
