Krayt dragon pearl

Krayt dragon pearls were gastroliths that could be found in the bellies of krayt dragons, a species of large creatures that could be found on the desert world of Tatooine. The pearls were exceptionally valuable and equally rare, given the extreme difficulty of killing the dragons that produced them.

Krayt dragons had a very long lifespan, and during the course of their life, would ingest stones to assist in digestion. The corrosive digestive fluid would break down and eventually dissolve the rocks. Rarely, a stone would contain a kyber crystal that would remain in a beast's gut being refined over the life of the dragon until it formed a smooth sphere. These pearls could vary in size from palm-sized to larger than a humanoid's head. Because the pearls were formed from kyber, they could be used in lightsabers. A lightsaber equipped with one of these pearls emitted a very powerful and destructive blade that emitted a howling sound when ignited.

The former senator Johhar Kessen, a notorious big game hunter, regarded a polished krayt dragon pearl paperweight as the ultimate trophy on Tatooine. In 9 ABY, a group of Tusken Raiders found a pearl in the corpse of a leviathan krayt dragon specimen.
