These hoop style earrings are crafted of 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 3mm wide x 1mm thick x 30mm (1.17") in diameter and weigh 3.10 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.
