Setting stones in metal clay after firing

Setting stones in metal clay after firing

Do you have a particular gem in mind that doesn’t work with firing? Don’t worry, you can still add it to your design. To create a bezel setting in metal clay without damaging the stone, use a fine bezel wire and solder it into the bezel as normal.

Not sure how?

Check out our blog on how to make a bezel setting. Once done, set the soldered bezel in place while the clay is raw, fire the whole design and then set the stone afterwards once it has cooled down.

Now you know what stones can be fired with metal clay, it’s time to get creative. For more inspiration on gemstone settings, view our Advanced Gemstone Setting Techniques visual guide below.
