Does anyone know if Bogoff signed all of their brooches?

I bought this brooch and earrings when I went for my Dr appt Thur.  Can't pass up a trip to a different store. I thought they were a set but the booch is unsigned and the backs are different. I am wondering if someone along the line just made a great marriage. I can't find anywhere that tells me whether they signed everything or not.

This looks like it might be a married set..I`m looking at the  design on back of the earring cups vs the brooch settings..they don`t match..

Even tho often only earrings OR brooch was signed (not all pcs)  the settings should still  match up
