Using wire gauge of your choice form 3 hoops, and thread andalusite stone on one hoop, amethyst on another and thread garnet on the last one.
Carefully thread each hoop through the ring.
Place on soldering block, and solder the wire rings together, for these stones I fired in place while they were on the hoop, they did not break.
However in most other cases, I use Kool Jewel to protect the stones from the heat.
