Korean Living National Treasure, Ryu Haegang (Yu Geun-yeong) - Self-made Goryeo Celadon Vase Largest diameter of the Korean vase: approximately 13cm x height: approximately 21cm A "Goryeo Celadon Vase" by Ryu Haegang (Yu Geun-yeong), a leading figure in Korean ceramics and a Living National Treasure ceramic artist. Purchased approximately 35 years ago at the Haegang Memorial Hall in Seoul during Ryu Haegang's lifetime. I remember it cost around ¥50,000 at the time. I have kept it carefully since then. The condition is good. There is a mark "Ryugu" on the bottom. It is a very beautiful vase. For those interested in celadon, please consider it.
