Make your own crystalline creation! Watch as we mix and pour resin into a handmade mold and add glittering embellishments to create a realistic effect. After 24 hours, the geode is ready to be put on display!



  1. Create a disposable mold on a covered board. Use a china marker to draw a working border and freeform geode shape inside the border frame.
  2. Place the clay on top of the drawn lines until they connect and create a closed shape.
  3. Use a box wood tool to press the clay down, attaching it to the covered board on all sides, including the inside. Make sure the seam is airtight on all sides to avoid potential leaks in the mold. Using a dry paintbrush, add the gel medium to all sides of the clay mold, including the inside and opening in the center, until it’s completely coated.

*Tip: To fix a leak in the mold, simply cover the hole with clay. 4. Glue the decorative rocks and glass to create the core of the geode. 5. While the border is drying, prepare your resin:

  • Be sure to work in a well-ventilated room, avoid contact with eyes and skin, and wear gloves.
  • Pour 20 ml of Hardener B and 40 ml of Resin A into a clean, dry container.
  • Mix the two components until the mixture becomes clear. Transfer it to a second container and mix again to ensure optimal uniformity of the resin. Stirring time can take up to 5 minutes.
  • Let the mixture sit in the container for 5 minutes to get rid of any bubbles.
  • Set aside a small amount of clear resin. Split the remaining mixture into three containers to create different colors. Add a few drops of fluid acrylics or alcohol inks to each cup.
  1. Start by pouring the clear resin on the geode’s core, coating the stones and embellishments.
  2. Pour the colored resin, alternating between colors in a circular motion starting at the center and working to the edge of the mold.
  3. You can use a heat gun to blend the colored resin.
  4. If desired, sprinkle glitter or crystal elements over the resin.
  5. Place your geode creation on a level surface, away from dust. Allow to dry for 24 hours.
  6. Remove your geode and throw away the mold.
  7. Lightly sand or add gold leafing to the edges of the geode if desired.
