Established by his father, Tsai Juihsing, in 1972, Tosho Sai now helms his namesake brand, which is known for their beautiful stones. Building on the brand’s past reputation and clout, as the president and designer, Tosho Sai has injected stronger and more distinctive design elements into his jewellery pieces, augmenting the beauty of quality stones with equally stellar design elements and creating pieces which can be passed from generation to generation. As an architecture major, it is his unconventional background which guides him to design from other points of view and to create pieces which are universally appealing, regardless of design training. With each piece, Tosho is first inspired by the stones.
When there is an outstanding stone which really catches his eye, he looks at the colour and then designs based on it, choosing complementary precious metals and accompanying stones to bring out its beauty. Then, he constructs a design based on architecture or nature to tie the story of each jewellery piece together, with intricate details. Every piece is entirely designed and created in Tokyo by Japanese craftsmen, who create works which are beautiful, wondrous and exciting beyond words.
