1950's Japan Sterling Smoky high quality Quartz Dangle Earrings

I love jewellery made in Japan in the 1930's to 50's. It was high quality and stands up to the test of time. I don't know why some of it is not marked like in this case, but I high quality have handled a lot of it and know by the way these are manufactured that they are Japanese and silver (tested and guaranteed). These earrings are 1 11/16 inches long from the top of the top stone to the bottom drop. The round smoky quartz is 8m and the bottom drop is over 22mm by over 15mm. It has a checkerboard facet front and pointy faceted back. These screw backs are in lovely condition with some minor inclusions to the natural stones. C. 1950. Follow me on instagram@jettesjewels.
