Hajime Ando
Joined AIGS school in 2019
Hajime Ando: My professional path began more than 30 years ago in Tokyo, Japan, my hometown. In university, I majored in metal craft, which is a traditional Japanese handicraft. After graduation, I started my career as a jewelry designer in Japan for ten years.
After my first trip to Italy, my love for Italian art and language led me to move to Valenza in 2001. Valenza is Italy’s major jewelry district in the region of Piedmont with the highest number of high-quality gold artisans and jewelry businesses in the country. Here, I continued to cultivate my passion for jewelry craftsmanship and became a designer for an Italian jewelry brand called LUCA CARATI.
Afterwards, I was a designer for Crova s.p.a, an Italian manufacturer of handmade jewelry founded in 1845. From 2005 onwards, I became one of the seven jewelry designers for Bvlgari in Rome.
