Krayt dragon pearl

Krayt dragon pearls were lustrous, colored stones found in the last chamber of the gizzard of krayt dragons. The stones were used to help crush food eaten by them, and over time, they became rounded because of how much they moved around. They could be found in colors such as blue, green, red, white and black. Due to a refractive quality peculiar to the pearl, they could be used in a lightsaber if properly cleaned, prepared and installed, though it was a difficult task. The pearls were seen as exceptionally valuable by the public (easily worth upwards of a hundred thousand credits each), as well as proof a person had killed a krayt dragon (to Tusken Raiders, a sign of bravery).

Both the Common and Greater Krayt Dragons produced pearls, however the pearls of the Greater Krayt were much larger and correspondingly much more valuable.
