The color changes depending on the viewing angle, and it's a very lovely stone. It's made of a mysterious stone called labradorite. It's like looking into the sea, or the colors of the universe, a blue-like green-like... I can't quite express it. I bought it at an accessory shop in Daikanyama, but I've forgotten the shop's name. It was a stylish shop. The meanings of labradorite are: "Longing," "Blooming of talent," "Connections," etc. Longing means to deepen one's feelings. This stone has the power to attract the person you long for, or to maintain a connection with a loved one who is far away. Used clothing store Vintage Antique
