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.
