Supplies to Make a Seashell Resin Pendant

  • A two part clear epoxy resin kit such as Envirotext Lite or Castin Craft
  • A plastic resin mold or cast from polymer clay for pendants
  • A mold release spray such as Castin Crafts mold release for epoxy resin.
  • Two craft measuring cups. Old medicine cups work well too.
  • Disposable mixing cups (I use Dixie cups)
  • Toothpicks or disposible crafts sticks
  • Miniature seashells either plain or colored
  • A bail for each pendant. You can use a pinch bail, glue on bail, or screw in bail that matches your piece of jewelry.
  • A standard drill with an 1/16" bit or craft drill that can drill through resin if using a pinch bail.

Instructions: How to Make Seashell Resin Jewelry

Prepare the Mold

If your mold is new, wash it with hot water and soap. Let it dry. Next,, spray the mold release product to the entire mold heavily, making sure it gets into every cup. Let the spray remain on the mold for at least 10 minutes. The, wipe the mold making sure there is no fluid in the cups.

Next, place shells, sand dollar, or miniature starfish inside the individual resin cups. Make sure the fancy side of the shell are facing down as this will be the side that will show on the outside of your jewelry.


Cast the Resin


Prepare the resin mix according to the package directions. Use the craft stick to slowy drop the prepared solution into each individual cup to cover the seashells.

Let the solutions settle for five minutes. If air bubbles appear you can pop them with the craft stick.

The resin mix will become solid in about 15 minutes. If the seashells rise or turn crooked, it is important to reset them with the craft stick before the solution hardens.

As the resin epoxy solution is curing, do not touch it. Fingerprints and stick marks will be permanently cast into the pendant. For best results, allow the solution to cure for at least 16 hours before moving it or touching it. When the resin is finished hardening, it will be smooth and dry.
