This is an Agate ring, size 11. It's a limited-edition Mariage Jet ring. Mariage Jet is a limited material created using a unique technique by Kuji Kohaku Co., Ltd., which fuses and refines natural jet extracted from 9,000-year-old strata in Kuji City, Sanriku, and natural amber, resulting in "Mariage Refined." This is an exquisite ring with a deep, rich black color, created with high-quality materials and techniques. I'm selling it because it no longer fits. Stamped with 'agete', '0.005', and 'K10' Retail price: 49,500 yen Color: Black系 (Black-based) Material: Gold Ring Size: 11
