Rubat Kyber Crystal

Raw rubat crystals are found growing from deposits of a variety of other minerals on N'dian and Spintir. The exact circumstances that lead to the forming of a cluster of rubat crystals are unknown, and are possibly related to their Force-attuned nature. In the initial stages, a thin film of crystal dust forms on the surface of the central deposit, before gradually expanding into a number of long spires—if left undisturbed.
The variety of rubat crystals used in lightsabers were made by selecting fully formed crystal growths, which could be up to a third of a meter in length, and carefully carving them down to a smaller, purified core.
A properly refined rubat crystal can produce a lightsaber blade of dazzling clarity. Some Jedi believed the carving and harvesting process amplified their bond with their crystal, though this may be the stuff of mere legends and folklore.
