If a unicorn and a rock had a baby, it would be this geode. Geodes start their lives as bubbles in volcanic rock or as animal burrows, tree roots or mud balls in sedimentary rock. Over millions of years, the outer shell hardens, and water forms on the inner walls. If the liquid contains dissolved minerals, it forms crystals within the cavity. This particular geode is already sold, but you can check Far Arden Essentials on Etsy for more shiny mystical accessories.
