On November 8, Sana, a member of popular girl group TWICE, made a splash when she visited the 'Graff Ginza Flagship Store' in Tokyo. The event marked the third anniversary of the store's opening and was celebrated with a special presentation of Graff's new jewelry collection.

As a brand ambassador, Sana was seen wearing Graff jewelry valued at over 7 billion yen (approximately $46 million USD). The centerpiece of her jewelry was a 205-carat diamond necklace. The necklace is the first of its kind in the world, made from the 'Meya Prosperity', the 29th largest diamond ever discovered.
