Thank you for viewing. This is a large, beautiful jade (hard jade) magatama with a clear, emerald green color and sparkling crystals. It may be called "roukan" in the world, and while those who love history may not know the authenticity of the jewelry, it is a very beautiful piece. There is some discoloration and weathering due to soil rust, but I believe it is jade based on its smooth luster, wear, and specific gravity. I heard it was excavated in the Kinai region. Size: Approximately 4.6 cm in length, approximately 1.5 cm in thickness, measured by an amateur. Weight: 26.7g Specific gravity: 3.29 Jade?! Comes with a wooden box. I ask that buyers make their judgment based on the images, understand the item, and agree to no returns and no claims, and cooperate with a prompt transaction. Please note that we do not offer dedicated listings to prevent trouble and delays; it will be first-come, first-served. #handmade #clearance #powerstone #goodluck #accessoryparts #itoigawa #rare #excavateditem #rare #accessories #necklace #bracelet #purification #amulet #fengshui #roukan #langgan #jadeite #nephrite #granular
