Like Power Crystals, Krayt Dragon Pearls can be used to improve the damage of a Lightsaber. They can be looted from Krayt Dragons on Tatooine, and come in a variety of qualities. As with Power Crystals, the quality determines the damage range the pearl can add.
Qualities & SourcesEdit
Flawless - Up to 20 damage (Looted from Ancient Krayt Dragons, or found in Buried Treasure)
Premium - Up to 19 damage (Looted from Ancient Krayt Dragons, or found in Buried Treasure)

There are also others named Ancient Krayt Dragon Pearls, which are always flawless and tune to up to 22 damage.
It has long been said that certain things can effect your odds of getting a good tune. Some say tuning near a Force Shrine, or having higher Luck, can result in better tunes. However, during the NGE conversion, it became apparent that crystals and pearls have set stats immediately upon looting them, they just simply are hidden until tuned.
There is also a rumor that pearls are stronger than crystals. This is untrue since the NGE. This rumor stems from pre-NGE when pearls and crystals had a speed modifier as well as a damage modifier. Back then, pearls had better odds of having a faster speed modifier, whereas crystals had better odds of having a higher damage modifier. When the NGE was released, there was a bug that left pearls with their speed modifier. For a short time, these old pearls were faster than new pearls and crystals. However the bug was promptly fixed and there is now no stat difference between crystals and pearls.
While SWG displays Krayt Dragon Pearls as a milky white sphere, similar to pearls harvested from clams in real life, this is actually incorrect. While real pearls are formed by a clam encasing a grain of sand in layers of calcium carbonate (CaCO3), Krayt Pearls are formed by Krayts eating rocks containing crystals. Inside the Krayts gizzard, the rocks grind together, eventually wearing away all the minerals, leaving only the hard crystal behind. This crystal still looks like a normal transparent crystal, and behaves the same way once refined by a Jedi.
Knights of the Old Republic also had Krayt Dragon Pearls that added to a Lightsaber's damage. Unlike SWG, their appearance was more correct, the items description stating: "Taken from the gullet of a krayt dragon, this crystalline "pearl" appears to have refracctory qualities that might allow it to function as a lightsaber cystal once properly adapted."
