This project explores the potential of herbal waste as a sustainable material source in jewelry design. Inspired by the environmental issues caused by both traditional enamel—whose production relies on toxic metals and mining—and the underutilized herbal residue generated in large quantities, I aimed to combine these two problems into one solution. Through a series of experiments, I extracted natural pigments and cellulose from herbs like mugwort, replacing parts of enamel’s mineral-based components with eco-friendly alternatives such as crushed beer bottles, eggshells, and volcanic ash. Although not all attempts succeeded, the process revealed valuable insights. The results are presented through a set of modular flower-shaped jewelry, symbolizing renewal and resilience. This project reimagines waste not as an end, but as the beginning of something beautiful through the lens of biodesign.

Adaptive Flower Jewelry: Ring and Brooch Variations

This image shows two silver flower pieces made with herbal enamel: a ring with green enamel and a brooch with translucent blue-green enamel. The modular design allows flexible styling for different occasions. By using eco-friendly, plant-based enamel, these pieces embody bio-design principles—blending natural materials with sustainable craftsmanship to create jewelry that connects nature and modern life.

Research and process

Herbs, colored extracts, pigment powders, and cellulose from plant waste shown during the early research phase.

From Herb to Enamel: Material Extraction Process

This image captures the early stage of material experimentation. It displays dried herbal waste, natural dye extracts, pigment powders, and plant-derived cellulose. These raw elements formed the foundation for creating herbal-based enamel, replacing synthetic or mined materials in traditional jewelry-making.

Testing Herbal Enamel on Ceramic and Copper

Enamel samples were fired on ceramic and copper bases to study how herbal pigments interact with different surfaces. Materials such as recycled glass, eggshell powder, and natural resins were added to test for color retention, gloss, and texture. These trials helped refine the final formula and application method for jewelry.
