Multi-color tourmaline three-strand bracelet. It's long enough to be worn as a necklace. I understand it's from an old mine. It usually looks like the colors in the 10th and 11th photos, but when light hits it, it's incredibly colorful and beautiful, and I'm captivated. There are also rare blue-colored beads. I liked the colors of this tourmaline and collected them, but I'm selling this unused one. ⚫︎ 5.4 mm diameter ⚫︎ Inner diameter approximately 15.5 cm It has been stored in a case, unused. I am selling it to someone who likes it, as I am organizing my natural stones. If you have any questions, please feel free to comment. Thank you.
