Ricardo 'Nano' Pulgar founded the WALKA Workshop with Claudia Betancourt in 2004, a collaboration initially aimed at finding new ways of working with ox horn (they are the third generation of craft makers). Later the workshop became WALKA STUDIO, an experimental space for the development of fashion collections, design objects, conceptual works and contemporary silversmithing workshops. He has exhibited his work in Chile, Australia, China, the United Kingdom and the United States.
Carolina Gimeno was born in Valparaíso, Chile. Being part of the third generation of a family of jewelers, her experience with jewelry making started at a very young age. Since 2002 she has been studying diverse areas of the craft and art of making jewelry in Barcelona. In 2010 she completed her degree in Artistic Jewelry at Massana School in Barcelona and finished her BA in Fine Arts, both with honors, at UPLA University, Chile. She held her first solo exhibition in Chile in 2011. She currently lives and works in Barcelona, taking part in exhibitions in the United States, Germany, the Netherlands, United Kingdom, Belgium, France, Egypt, Spain and Chile. In 2009 she co-founded the collective Bórax08001. Her contact with European contemporary jewelry has influenced her understanding of the new jewelry as a manifestation of the arts and not only as a mere ornamental craft.
