Inspired by the lyrics of a song - 'The ring you gave me last summer, only white empty marks break my heart,' Inner Message was designed in 2007 during the senior year of its creator, Jungyun Yoon, while she was studying at Hongik University in Seoul, South Korea. Initially, the Inner Message ring was exclusively showcased through online photos, which generated a significant number of purchase requests. In response to this growing demand, she established a studio in Seoul in 2008 and began offering Inner Message rings for sale. Since then, she has relocated to the United States, where she set up a studio in California.
