Hi, everyone! Welcome to this polymer clay crystal jewelry tutorial. This time, we’re going for a faux crystal geode look.


This technique can be used for many different jewelry items, it’s so fun to do, and it looks incredible. Let’s get started!

Tools and materials:

  • Base clay
  • Transparent clay 
  • Liquid clay or bake & bond
  • Glitter shards
  • Paint
  • UV resin
  • UV lamp
  • Roller pin 
  • Shape cutter
Flattening clay with a rolling pin

1. Flatten the clay

Take your base clay and condition it by using a roller pin to get it as smooth and flat as possible.


I also put mine through the pasta machine a couple of times, but if you don’t have one, the rolling pin should do the trick.

Cutting out shape in polymer clay

2. Cut out the clay

Use a shape cutter to cut out a few pieces of the clay. You don’t have to stick with the circle - any shape will do.

Tracing the shape of the geode

3. Trace the shape of the geode

Now, trace out the shape of the geode in the clay. This is where we’re going to put our crystals. I’m using a dotting pen, but you can use any tool like a hairpin or a pencil.

Chopping up translucent clay

4. Chop up translucent clay

Next, chop your translucent clay into very tiny pieces. The bigger your geode, the bigger the piece, but for this project, they should be rather small. 

Applying liquid clay or bake & bond

5. Apply liquid clay or bake & bond

Now, you want to take your liquid clay/bake & bond and add a little bit to your geode shape. 

Spreading it out with a brush

Spread it out evenly with a brush, or whatever you have on hand.

Adding pieces of translucent clay

6. Add pieces of translucent clay

Very carefully add the pieces of translucent clay to the liquid clay/bake & bond.

Adding glitter around the geode edges

7. Add glitter around the edges

Time to add glitter! Add a bit of liquid clay/bake & bond to the tool and carefully pick up the pieces of glitter.


Start by attaching the gold glitter to the outside of the small pieces of translucent clay to create the geode shape.

Adding gold paint around the geode edges

8. Add paint around the edges

I like to use paint around the edges of the geode as the glitter shards can bleed a little bit, and this antique gold paint will help cover any redness that seeps through.

9. Bake

Bake at 250°F for 25-30 minutes.

UV resin instructions

10. Apply UV resin

Once they’re finished baking, apply UV resin to the translucent clay.

11. Add glitter to the inside of the geode

More glitter! I’m adding this fun mix of opal and rainbow glitter shards on top of the uncovered translucent clay to create the crystals within the geode.


Don’t forget to use liquid clay/bond & bake to help it attach easier.
