So, after she received a master's degree from the University of the Arts London, she went to the Gemological Institute of America - the world's most foremost authority on diamonds, colored stones and pearls - to join its Graduate Gemologist program.
There, she gained both technical expertise and practical skills to evaluate gemstones.
Later, she went to the Gublin Academy in Switzerland. And in 2016 she was admitted to the Haute Ecole de Joaillerie in Paris.
The Haute Ecole de Joaillerie, founded in 1864, is a place where most of the luxury brands such as Cartier, Van Cleef & Arpels, Chanel, Dior and LVMH have their jewelry craftsmen from.
Speaking of her time there, Feng, who was then the only student speaking Chinese in those workshops, says: "Their superior craftsmanship deeply impressed me. I studied with French ateliers there, and spent hundreds hours on attaining perfection."
