This is sunmoonstone, which combines the aventurescence of sunstone and the schiller of moonstone. You can enjoy the changing sparkle depending on how the light hits it. (It's difficult to see in the image, but the actual stone has a strong effect) ⚫︎12mm size It has been stored in a case without being used. I am selling it at a low price to organize my natural stones. I will sell it to someone who likes it. If you have any questions, please feel free to comment. Also, if it can be combined with other items, I will offer a discount for combined purchases. Thank you. *I will not offer individual discounts on items under 1000 yen.
