◉ The item was removed due to an issue, but has been restored. We apologize for the inconvenience. ◉ The cross is made of silver 925. The hook is 18k. ◉ The hook has not deteriorated at all, even during long-term storage. Also, the cross can be polished with a silver polishing cloth to make it shine like new. ◉ I checked the engraving with a loupe, but couldn't find it. However, I confirmed the material at the time of purchase, and the price was not cheap. However, if you are concerned, please refrain from purchasing. ◉ This item was also purchased at a select accessory shop in Higashi-Ginza when I was young. Thank you for viewing.
