These "J-Hoop" style earrings with post 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 30mm (1.19") and weight is 7.0 grams. The earrings are marked 925 on the inside as well as the backs. These earrings were part of a store stock that I recently purchased from a jeweler's estate. They are brand new.
