Formation & geological history
Formed in sedimentary basins through the precipitation of silica from seawater or groundwater, often associated with diatomaceous earth deposits.
Uses & applications
Primarily used as a pocket stone for metaphysical purposes, meditation, and by mineral collectors for its unique 'biomorphic' shapes.
Geological facts
Also known as Fairy Stones or Goddess Stones due to their smooth, rounded, often anthropomorphic shapes that resemble small sculptures.
