Influenced by the artistic heritage of her family, Cindy Chao started her design career after graduating from the renowned F.I.T. (Fashion Institute of Technology) and G.I.A (Gemological Institute of America), in New York. 
With a keen sense of fashion and design, in both western and eastern markets, Cindy Chao established her first showroom in Taipei, Taiwan, in 2004, under the name 'The Art Jewel'. 
Drawing on techniques from the 18th century, and with the desire to break boundaries and redefine high jewellery, Cindy Chao's goal was to handmake each jewel as a miniature work of art, therefore presenting rare, unique, bold and sculptural jewels to connoisseurs of jewellery and her distinguished group of collectors.
Further to exhibiting at various prominent museums around the world, such as the Tokyo Mori Art Museum in Japan, Beijing's Today Art Museum in China and at Masterpiece London, Cindy Chao has also had the great honour of being invited to bestow an iconic piece of her work to the Smithsonian National Museum of Natural History, in the USA.
