These hoop style earrings are crafted of solid sterling silver .925 with a rhodium plating, offering it the look of luxurious white gold at a fraction of the price. Size of the hoops is 2mm thick x 35mm (1.36") in diameter and weigh 4.10 grams. The earrings are marked 925. These earrings were part of a store stock that I recently purchased from a jeweler's estate. They are brand new.
