These earrings were purchased at a shop in Okinawa several decades ago. I've worn them a few times and stored them for a long time. I was told the stones are zirconia, but I'm not certain. They sparkle beautifully. I think they're silver, but the hallmark is too small to read. It looks like 925, maybe. The earring backs are discolored. Please polish them. The overall construction feels a bit rough. These are used items, so please refrain from purchasing if you are concerned about minor details.
