This necklace was purchased over 20 years ago during a trip to South America. It features sodalite, a stone native to Peru, which resembles lapis lazuli. It has no front or back, allowing you to enjoy the stone's appearance from both sides. It was handmade by local people. I think it's easy to wear because it's a lightweight material. The local people called the metal material alpaca. It has been stored at home for a long time, unused and in new condition. Thank you very much.
