We have Rhinestone Earrings vintage screw back.  I'm not sure if they are nos or not but they are on a satin backed card (mildly discolored backing).  They are screw back.  The earrings measure about 1" in L x 3/4" in W with a small curve to the front.  The stones are all in there own settings.  They resemble christmas trees to me.....the stones are clear and blue.
