Vintage Schreiner Unsigned ? Pink + Green Rhinestone Pin + Clip Earrings READ

Vintage pink and green rhinestone pin and earring set. I have been told they are unsigned Schreiner pieces. PLEASE note the pin is missing a rhinestone and some of the metal backing is tarnished or shows some metal loss on all pieces I cannot tell if some of the stones on the earrings at the edges are damaged.It is hard for me to tell as I do not have a jewelry loop. Therefore I am selling this AS IS because it may have some condition issues due to its age or prior use I have tried to show a close-up of the missing rhinestone on the pin in the third picture in my listing These belong to a relative who did not want to sell these at first, but when she found out that they are not ordinary pieces, she decided she would sell them and use the money for something else that she would like to purchase. I am selling these as UNSIGNED as I do not find a signature of any type, so please use your jewelry expertise before you purchase these and if you have any information about these, I’d be happy to hear the information.Beautifully designed and gorgeous colors
