Ruby Red Rhinestone Vintage Drop Earrings-Schreiner ?

A gorgeous pair of deep red earrings which are thought to be unsigned Schreiner who was a master of twentieth century costume jewellery produced in USA.  I am unable to verify that except to say that the quality is very good with some known Schreiner attributes, in particular the little ruffled cabochon that holds the smaller stones. There are clip on components, both firm and comfortable. Length of the drop is 5cm and width of the large tear drop shaped stone with surrounding smaller stones is 2cms. Width of the piece to the ear clip is 1.5cms. Beautiful earrings,in perfect condition, gift boxed by Vintageonline.
