Silver-colored hardware and a teardrop-shaped necklace with a brown stone. Chain color: Silver Hardware color: Silver Chain length: Approximately 47cm No case Received from Kenshoen, a kimono shop. There is no certificate of authenticity, but I was told it is some kind of stone. Although it is unused, it has been carefully stored at home in a bag for many years. It has a simple design that is not too flashy, so I think it will be easy to match with various outfits.
