This study explores coloured bacterial cellulose in the creation of modern jewellery in the context of sustainability, innovation, and cultural expression. Having long relied on the historic noble metals and gemstones, the jewellery industry increasingly is looking to experimental and natural material. In Brazil, the movement has been guided by environmentalism, regional culture, and the aesthetic potential of non-traditional raw materials such as plant fibres, seeds, and microbial biomaterials. The novel function of material designers and the growing role of biofabrication and bio-based material have gained attention in design methods in the latest scenario, notably in the case of bacterial cellulose, a biodegradable and multi-functional biomaterial produced by microbial fermentation. In the case study, BC is dyed in natural indigo, a highly culturally symbolic and environmentally worthwhile colourant. All the steps of the process—to cultivation to colouring through finishing to use in recycled-silver configurations—are detailed. Colour is examined in the function of the ultimate design agent in determining the psychological, cultural, and emotional aspects of user experience. The use of natural colourants enhances the aesthetic attractiveness and cultural acceptability of biomaterials, adding symbolic connotations and allowing for sustainable storytelling. The findings show BC to possess favorable performance properties, qualifying the material for jewellery making. Low costliness, availability, and environmental friendliness are additional factors contributing to the material's inclusion in small-scale and craft production. This research confirms that coloured bacterial cellulose is a promising material for the future of biojewellery design. It enables professionals to create artefacts that are visually compelling, culturally resonant, and environmentally responsible. Moreover, it contributes to the ongoing discourse on how contemporary design can harmonise tradition, material innovation, and ecological awareness, pointing to new directions in wearable art and sustainable material futures.

摘要

This study explores coloured bacterial cellulose in the creation of modern jewellery in the context of sustainability, innovation, and cultural expression. Having long relied on the historic noble metals and gemstones, the jewellery industry increasingly is looking to experimental and natural material. In Brazil, the movement has been guided by environmentalism, regional culture, and the aesthetic potential of non-traditional raw materials such as plant fibres, seeds, and microbial biomaterials. The novel function of material designers and the growing role of biofabrication and bio-based material have gained attention in design methods in the latest scenario, notably in the case of bacterial cellulose, a biodegradable and multi-functional biomaterial produced by microbial fermentation. In the case study, BC is dyed in natural indigo, a highly culturally symbolic and environmentally worthwhile colourant. All the steps of the process—to cultivation to colouring through finishing to use in recycled-silver configurations—are detailed. Colour is examined in the function of the ultimate design agent in determining the psychological, cultural, and emotional aspects of user experience. The use of natural colourants enhances the aesthetic attractiveness and cultural acceptability of biomaterials, adding symbolic connotations and allowing for sustainable storytelling. The findings show BC to possess favorable performance properties, qualifying the material for jewellery making. Low costliness, availability, and environmental friendliness are additional factors contributing to the material's inclusion in small-scale and craft production. This research confirms that coloured bacterial cellulose is a promising material for the future of biojewellery design. It enables professionals to create artefacts that are visually compelling, culturally resonant, and environmentally responsible. Moreover, it contributes to the ongoing discourse on how contemporary design can harmonise tradition, material innovation, and ecological awareness, pointing to new directions in wearable art and sustainable material futures.
