Meet designer and co-founder Nisme Castro and co-founder Natan Felzensztein. Since she was a girl, Nisme has always been attracted to jewels and stones. She would always open her mother's jewelry trunk, wear them and even "make adjustments" to them. From here came the dream of having his own jewelry. Upon meeting Natan, they both decided to undertake together and make this dream come true. Together they took classes in goldsmithing, manufacturing, precious stones and everything related to jewelry.
