A stylus used by Yaru Korsin in 3000 BBY was made of diamond. Uvak-mounted Keshiri of the Alanciari military's air force successfully used diamonds as a flak projectile weapon. Corran Horn used a diamond to power his dual-phase lightsaber. However, the first gem he used turned out to be Kubaz xirkonia instead, which burned out during a confrontation with Shala the Hutt. Corran later replaced it with a real diamond.
