Each earring features four lustrous pearls ranging in size from 4.8 to 4.2 millimeters. Perfect to collect and wear, these gorgeous classic estate earrings have non-pierced screw backs and measure 3/4 inch high and 7/8 inch wide. The Mikimoto hallmark of an "M" in an oyster shell is clearly visible on the back of each earring.
