MAR.03 is an unisex jewelry brand established in 2022 based in Tokyo.


Pursuing a simple and sophisticated balance centered on sterling silver,

the brand expresses the essence of people and the beauty behind them.


Designed with architectural elements in a minimal yet modern silhouette,

the Punching series is a signature item of the brand and is made by Japanese craftsmen.

The beauty of the back that can be seen through punching shows the world of MAR.03

and at the same time adds new imagination.


Our goal is to fit into people's lifestyles,

and we look forward to meeting people who have their own attractive attitudes.
