Mix a small part of the Ceralun according to the instructions. The amount of clay you need will depend on how raised you want the finish to be.  

Roll the clay into a ball and gently press into the middle of the circular ring setting.

Using the flat pad of your finger, gently tap and press the clay evenly until it reaches the edges of the ring.
Continue to smoothen the piece, creating a flat & even surface.

Decide on what design or pattern you want to achieve, choose your Swarovski crystals and begin to press them evenly into the clay. Make sure the back of the crystal is completely submerged below the clay so that the line edge fits flush to the clay. 

Once your pattern is complete, dampen a cotton bud and gently wipe it across the surface of the clay for a soft shine.
After the clay has fully hardened (up to 72 hours) your ring should be ready to wear!
