- "It worked fine when you tested it initially. Synthetic?"
"Kubaz xurkonia. The crystalline latice handled the energy while we tested it, but it was probably ready to go down anytime."
- ―Elegos A'Kla and Corran Horn
Kubaz xirkonia was a type of mineral that was used in the creation of fake diamonds.
Corran Horn used a kubaz xirkonia gemstone during the construction of his dual-phase lightsaber, although at the time he believed it was a diamond. Although the gem held up during testing, it burned out a short time later during a confrontation with Shala the Hutt. Corran later replaced it with a real diamond.
