This is a handmade necklace made by a relative. Recycled parts may be used only for the metal fittings. It seems to use natural stones and beads. The transparent natural stone appears to be crystal. I don't know about the rest. I was told that they use proper materials, so I think it's made with good materials... It is made very carefully, but I am selling it at a low price. This is a handmade item by an amateur, so please be aware of minor imperfections. …………………………………………………………………………… ◎ We cannot sell individual items or offer discounts. ◎ We will ship with simple packaging. ◎ We usually ship within 2-3 days, but it may take 4-5 days if it includes weekends or holidays. ◎ Please note that I may not be able to reply to messages immediately, such as during work. ◎ If you send a message at night, I may not be able to reply until the next day.
