DEEP DIVE
What are Kyber Crystals?
Kyber Crystals were a rare crystal, strong with the Force, that grew on various planets throughout the Galaxy. They were an all-powerful object that truly harnessed the power of the Force within them.
Their main use as seen throughout Star Wars has been to help the Jedi & Sith in the creation of their Lightsabers. The Kybers are what channel the Force and give Lightsabers their signature energy rod.
While crystals used in Lightsabers are generally very small (in order to fit within the Hilt), they do grow in all shapes & sizes, so much larger Crystals do exist.
HOW TO USE A KYBER
LIGHTSABERS
The most common use for a Kyber was being place in a Lightsaber Hilt. Jedi & Sith could use a Kyber to activate their Lightsaber's energy rod. Depending what kind of Kyber you were gifted from the Force, your Lightsaber could be one of a variety of different colours.
ENERGY
As objects with a significant amount of power, Kybers are always at risk of being used for evil. In the Sequel trilogy, the First Order turned the ancient planet Ilum, a place where Jedi used to obtain their crystals, into a Kyber mine. They then used these crystals to help power Starkiller Base.
ATTIRE
Have a Kyber that doesn't work anymore? Throw it on a necklace! Jyn Erso's mother in Rogue One gave her this necklace when she was a child & she still wore it years later. I guess if it can't power a Lightsaber or a destructive weapon, might as well keep it as a souvenir of times past.
HOW DO YOU GET A KYBER?
THERE'S A FEW WAYS
For the most part, Kybers were originally found during Jedi rituals. Young Jedi who were finally ready to build their own Lightsabers would head to the Crystal Cave on Ilum and complete 'The Gathering'.
'The Gathering' would have Jedi face & conquer their deepest fears. If they were successful, they would earn a single Kyber. The Force would decide which colour they receive once they do.
While Ilum was the most common way to find a Kyber, there are other ways to acquire your own. In Star Wars: Rebels, Ezra Bridger heads to the Jedi Temple on Lothal to test if he's ready to be trained as a Jedi. He didn't go with intent to get a Kyber, but the Force decided he was ready and awarded him one.
The Sith aren't able to harvest a Kyber in the same way. Some Sith are Jedi-turned-bad and have taken their pure Kybers and corrupted them (making the Red colour). Others have killed Jedi and corrupted the original owner's Kyber and taken it for their own.
Finally, Jedi are also able to take back Kybers from a Sith and repair it, bringing it back to the light side of the Force.

MYSTERY KYBERS
You can purchase a Kyber in these mystery tubes. The colour of the tube tells you what colour your Kyber will be, but there are various shapes & sizes of each to find. There is one exception that we will get to in a moment.
