All kybers were attuned to the Force regardless of their size. They had no discernible lifespan, and thus could be found from sizes as small as a fingernail to gigantic proportions. The crystals grew in an organized way, adding to their prismatic structure one piece at a time. If an individual were to wrap their hand around a crystal, the crystal would warm, but not change in temperature. Kyber crystals would not warm a sheath or a towel or any inanimate object, responding only to life, including plant life. Kyber crystals were sturdy enough to survive the violent explosion of a lightsaber's power grid, such as those caused by accidentally inverting the emitter matrix during the weapon's assembly. They were stable at temperatures and pressures found in the cores of large stars, and were thus impervious to fire and resistant to hammering, and noted for their intricate patterns.

Internally, kyber crystals were composed of both organic and inorganic matter. Īn uncolored kyber crystal used as the pendant of a necklace Some theorized that the permutations in the kyber lattice were comparable to emotional shifts in a sentient being. The crystals exhibited a sort of 'collective consciousness,' verging on sentience, and could non-verbally communicate with both one another and living beings. The crystals concentrated energy in a unique manner through the Force, resonating with it. Kyber crystals were Force-attuned crystals that grew rarely but throughout the galaxy, with some areas having a greater abundance than others. Blades with damaged kyber crystals can still function, but the energy they emit can often be as dangerous and unpredictable as the person willing to risk wielding them. Red lightsabers are typically attuned to those who have succumbed to the dark side of the Force. Some of the most common colors for Jedi lightsabers include blue, green, and violet. The color of the crystal determines the color of the lightsaber's blade. Each kyber crystal starts out clear, but once it is awakened by the Force, its color shifts to match the nature of its master. Each kyber crystal is unique and requires a Force-sensitive being to align and activate it during the lightsaber assembly process. They can be found on planets that have a high natural concentration of Force energy, such as Jedha and Ilum. ' Kyber crystals are rare gems capable of focusing and amplifying energy. When these tempered crystals are placed within a weapon such as a lightsaber, its color will change within moments upon being picked up by a new wielder. Through an unspecified process involving being placed in a furnace and hammering, kyber crystals could be tempered to match with the nature of multiple individuals multiple times, beside bonding with just one for life. There were also larger, rarer crystals of great power and that, according to legends, were used at the heart of ancient superweapons by the Sith. The crystal's mix of unique luster was called 'the water of the kyber' by the Jedi. As part of their Jedi training, younglings were sent to the Crystal Cave of the ice planet of Ilum to seek their own lightsaber crystals. Known in ancient times as a kaiburr crystal, it was used by both the Jedi and the Sith in the construction of their lightsabers. ' The strongest stars have hearts of kyber.' ― Chirrut Îmwe Ī kyber crystal, simply known as a kyber and described as a lightsaber crystal or the living crystal, was a rare, Force-attuned crystal that grew naturally and was found on various planets across the galaxy.
