A blade that evokes a sense of timeless history— This is a jade sword, a "Kōkogyoku" (ancient jade) believed to have been crafted from the Warring States period to the Han dynasty. "Kōkogyoku" refers to jade artifacts made before the Han dynasty, and they are precious relics that convey the profound culture and aesthetic sense of ancient China. They retain their beauty even after the passage of long years, and are exceptional pieces that convey the weight of history. The texture and luster of the jade itself, and the feeling of weight when held, offer a unique charm that cannot be experienced with modern crafts. This is one of the items that came to light while organizing items passed down from my collector grandfather. Details such as appraisal, the period of the collection, and the artist are unknown. Please examine the images carefully and make your own judgment regarding the condition. • Size: Length approx. 40cm / Width approx. 5.7cm / Thickness approx. 0.7cm • Purpose: For appreciation, as a collection or research material ※ This item is an antique jade artifact intended for collection, decoration, and appreciation.
