Swarovski Material: Zirconia (1.5mm) Size: 50 (approx. US size 5) Color: Silver Purchased at a duty-free shop. No certificate or box included. Size 50 and Swarovski are engraved on the inside. The delicate design allows for layering, as shown in the third photo, creating a beautiful look similar to Quatre rings. There are no noticeable scratches or missing stones, but it has been stored in a jewelry case for a long time, so please refrain from purchasing if you are concerned. The ring will be shipped via Yu-Packet Post Mini or Nekopos (Japanese shipping services). Thank you.
