Healing Crystals of Fire
From Wookieepedia, the Star Wars wiki.
The Healing Crystals of Fire were one of the greatest treasures of the Jedi Order and were kept under tight security in one of the Coruscant Jedi Temple's meditation chamber during the years of the Galactic Republic. They were used to help heal serious wounds in the Halls of Healing. The crystals got their name from the flame that burned inside them which was said to be eternal. During a serious of robberies, the Dark Jedi Xanatos attempted to steal these precious stones. He took the stolen stones to the Temple's fusion furnace in an attempt to destroy the Temple, yet Qui-Gon Jinn figured out Xanatos' plans and recovered the crystals in time.
