Vintage Sarah Coventry (?) Silver Tone Red Teardrop Bead Center Clip Earrings

I put a question mark next to Sarah Coventry, because while they did come in this plastic container (it’s yellowed with age) marked Sarah, the earrings themselves are not marked, and it was very rare for this maker not to mark items. I could not find these earrings in my research, nor the number 5434z It may very well be Sarah, I just could not find it in my research. They appear to never have been worn and are in excellent condition.
