I purchased this at a Malika store. The turquoise is a raw stone from Tibet, commonly called Tibetan, and is very rare. Especially this greenish color is a rare find (dark green). Furthermore, the silver beads use sterling silver, and the bead section uses old antique beads from the time, so please enjoy the slight color unevenness and gradation. I think it would also be nice to wear it over a turtleneck sweater in the coming season. Turquoise is said to be good for success, accuracy, prosperity, and warding off evil. The purchase price was 57,500 yen. Please consider this if you understand old antique and retro items. If you have any questions, please feel free to comment, and I will answer them. Thank you.
