Worn only once. Has been kept in an accessory case ever since. There is a slight rust on the back. I don't know where it's from, but I bought it in Osaka (at one of the stores shown in the 6th photo). Gold-plated hoop earrings with blue opal-like stones. - Color: Blue - Material: Gold plating - Design: Hoop earrings - Stone: Opal-like stone
