Tradition and innovation
SIKNO combines jewelry-making heritage with an innovative, highly technological industrial vision. With four decades of expertise in jewelry manufacturing, since 2019 we have operated as a B2B manufacturer, becoming a strategic partner for today’s leading jewelry brands.
Continuous improvement and quality are the pillars of SIKNO’s culture. These values, driven by founder Ricardo Leal over more than 40 years at CL Grupo Industrial, remain fully embedded today under the leadership of the second generation of the Leal family.
