These Israel-signed 925 sterling silver chunky modernistic ribbed half hoop pierced earrings weigh 17.22 grams. The earrings feature a unique half arc shape or C shape with an omega back closure for secure wear. I believe they are hollow making them comfortable to wear. Made from high-quality silver and measure 3.25 inches long, 1.75 inches wide, and are crafted in Israel, making them a special addition to any jewelry collection. I could not get a good photo of the marks on these as it is under the clip.
