Geode resin is a decorative art material used to create pieces that resemble natural geodes or crystals. It involves using clear or colored resin combined with pigments, glitter, and sometimes crushed stones or crystals to mimic the appearance of real geodes. Artists pour the resin into molds or onto surfaces, layering colors and textures to achieve a sparkling, three-dimensional effect. This technique is popular for making jewelry, coasters, tabletops, and other decorative items that showcase the beauty of natural formations with a glossy, smooth finish.
