These unique flat druzy chalcedony concretions from Progresso, Rio do Sul, Brazil feature a natural disk-like form shaped over time within ancient sedimentary layers. Composed of microcrystalline quartz, the soft sparkle and subtle banding give them an earthy, organic beauty. Each piece is one-of-a-kind, making it a perfect addition for collectors, display, or those drawn to grounding, stabilizing stones.
