I purchased these earrings around 2023 from the Tokyo Jewelry Index for about 50,000 yen and have worn them twice. They feature the birthstone for March. They have a beautiful sparkle, are large, and have a strong presence. The bright blue color is refreshing and makes your face look radiant; they are very beautiful. The simple design makes them suitable for any situation, whether the office or casual wear. I have lost the warranty card, but they are genuine, so please rest assured. The posts are platinum 900, and each earring has 0.63ct, totaling 1.26ct. Please refer to the photos. The size is 8mm x 5mm (approximate measurement). No box included. They will be placed in a plastic bag, wrapped in bubble wrap, and shipped via Yu-Packet Post Mini. If you need a box, I can include one for an additional ¥300; please comment if you would like one. Please note that the box has some stains. Both shipping options are anonymous. I am also open to offers, so if you are interested, please comment with your desired price (^^) As these have been used once, I am looking for buyers who understand that they are pre-owned. Also, to prevent any swapping, returns are not accepted.
