On November 8 JST, TWICE member Sana made an appearance at the 'Graff Ginza Flagship Store' in Tokyo. On this day, a special showcase was held to commemorate the store's 3rd anniversary since its opening, including the unveiling of 'Graff's newest line of jewelry. 

Currently active as an ambassador for 'Graff', Sana appeared at the event donning on 'Graff' jewelry worth over 7 billion yen (~ $46 million USD), including a centerpiece necklace made of 205-carat diamond. The piece is known to be the world's first 205-carat diamond necklace, crafted by 'Graff' from the 'Meya Prosperity', the 29th largest diamond ever uncovered.
