Very sharp architectural look! Is absolutely fabulous worn on a black ribbon or cord and the 2 inch pendant also wears as a pin / brooch. Screw back earrings are 3/4 inches. All pieces are marked Silver Mexico, test at a little better than 925 and are guaranteed Sterling Silver. The screw back findings have the original placements in slightly different positions on the earrings backs (one a little higher) yet wear equal and well by simply adjusting the placement on your earlobe. Ca., 1930 and wears beautifully!
