JOMAZ Joseph Mazer Rhinestone Clip On Earrings from the 50s

The JOMAZ signature was used from 1944 to 1981 by Joseph J. Mazer and Co. Originally he designed with his brother, Louis and the mark was Mazer Bros. This piece is probably from the late 50s to early 60s. The earrings are clip on or clipback with all crystal stones and rhodium plating on the metal. They are 1 1/4x3/4" and are in very good condition but I do see a couple of dark stones. They are marked JOMAZ on the back of the clip with a Patent number on the side of the clip. I can't read the number as it is too small for me.
