The brand name "gren" was coined by designer Midori Yamada after the nickname her aunt called her when she was young. She loves the color ``green'' in her name, and her atelier is a space full of greenery, bathed in light from large windows and surrounded by plants that grow freely. The creations are not limited to jewelry; sometimes the atelier becomes a private kitchen where the designer can entertain important guests with home-cooked meals. Grin's jewelry is created in an atelier full of dreams.
