Antique obi止め (sash fastener). As this is an old item, there are some slight distortions and color unevenness on the metal fittings. The stone is very clear and beautiful, but upon close inspection, there appears to be a chip in a place hidden by the metal fitting. It may have chipped when the metal fitting was attached. Please understand that this item has been stored at home for a long time. Thank you for your understanding.
