This set of freshwater pearls has cubic zirconia at the top of the earrings in the front of the loops and in the back there’s a design. The freshwater pearl necklace is on a 18” sterling silver chain. You can tell if a freshwater pearl or an expensive pearl is real is by rubbing them across your teeth and if they feel gritty then they are real. You can see in the picture that I posted that it says 925. That’s the sterling silver sign. This is prettier in person than in the picture!
