Circa World War II era round sterling silver crab screw back earrings. Marked "Joseff" and "Sterling Silver." Measure: 1 1/6 inches across. Condition: Very good; tarnish normal for their age (they have not been polished), one screw back seems different than the other but they look to have been made this way. Joseff made jewelry for Hollywood movies. The zodiac line was made into the 1950s, but the use of sterling and screw backs rather than clip backs mark these as having been made earlier.
