Crystal Cave SWGTCG

Lightsaber crystals

"The crystal is, by itself, the power source of the weapon. Like the Force user, the crystal is attuned to the Force. Without that attunement, the crystal is just a rock. And while a non-Force user could probably ignite and wield a lightsaber, the crystal is needed to be properly attuned to the Force. But for a Jedi, the lightsaber becomes more: it is a manifestation of a Jedi's connection to the Force."
Jaden Korr[1]

Lightsaber crystals, also known as Focus crystals or kyber crystals, were a variety of crystals, gems, stones, or other objects that were used as the energy source of a lightsaber.

At the heart of every lightsaber was a single crystal that resonated to produce the efficient, powerful blade. While the most common crystals used in the process were from the Adega system, Ilum and Dantooine (in the so-called Crystal Cave), Jedi and Sith used a variety of crystals to produce various colors, effects and unique abilities. Some crystals could even enhance the Force skills of a particular user. Other gems, such as colored crystals or diamonds, were used exclusively for prismatic effects. However, not all lightsaber focus crystals were actually 'crystals'. Plenty of Jedi or Sith used a different material or substance in place of a crystal, such as physical remains, shards of glass and even special micro machinery.

During the Great Sith War epoch, many lightsabers were created using Kunda stones, a natural geologic formation from the planet Kadril, in place of crystals. These stones boasted numerous practical applications in medicine and communications; however, when added to other focusing crystals, they produced a broader beam.

A Jedi constructs his lightsaber during the Galactic Civil War.

Before placing the crystal in the lightsaber, the Jedi or Sith had to imbue it with the Force. To do this, the Force-user was required to meditate on the crystal for many days. Luke Skywalker meditated on his crystal in Ben Kenobi's home with only R2-D2 to keep him company.[3]

While the Jedi mostly used natural crystals, the Sith usually used red-hued synthetic crystals. However, Luke Skywalker created his lightsaber using a synthetic crystal, because he had no access to natural crystals on Tatooine. Sith-made synthetic crystals created a slightly more powerful blade when energized by the dark side of the Force. Sith lightsaber blades could occasionally "break" the blade of a Jedi saber. Darth Sidious had Darth Maul use a special furnace to make his own crystals. Maul worked constantly for several days to make the four crystals needed for his double-bladed lightsaber. Their creation required intense concentration, as Darth Maul had to use the Force not only to make them the proper shape and to ensure that the crystals were free from impurities, but also to keep himself alive for the long time it took in the blistering heat of the furnace. Maul was particularly proud of this achievement and believed it to be an example of the Sith's superiority over the Jedi. However, Sidious did not make his subsequent apprentices—Tyranus and Vader—create their crystals in such a manner, instead supplying them himself.[4][5]

Luke Skywalker, who had decided to create his lightsaber crystal instead of using a natural one, also used a special furnace he found in Obi-Wan Kenobi's home to prepare his crystal.[3] As exemplified in both Skywalker and Maul's cases, the creator of a synthetic crystal channeled his Force energies and personality into the crystal as it was formed, making it unique in every way, including the color.

The Jedi Order had an advanced technique that allowed, in case of need, the cleaning of synthetic crystals made by dark-side users from the hate of their former owners. In 41 ABY, Jaden Korr, who had lost his second lightsaber, used the Force to banish the dark side from the red crystal of a Dark Jedi he had killed. Through meditation, he was able to remove all traces of the dark side and imbue the crystal with the light side, turning the Dark Jedi's lightsaber into a yellow-bladed Jedi weapon.

"The time has come for you to choose the color of your lightsaber. This color also reflects your demeanor and position within the Order."

Around 4000 BBY, lightsaber focus crystals were used to indicate a Jedi's chosen class. Blue indicated a Jedi Guardian, a Jedi who used the Force on a more physical level. Green indicated a Jedi Consular, a Jedi who preferred to reflect on the mysteries of the Force and fight the dark side at its heart. Yellow indicated a Jedi Sentinel, a Jedi who honed his or her skills in a balance of combat and scholarly pursuits.

This distinction fell out of practice in later years, when most Jedi used blue or green crystals from Ilum caves based on personal choice, and then the use of crystals coming from various source worlds became marginal. However, specific roles like the Temple Guards all used yellow crystals to power their lightsabers. Purple and orange crystals were still used by some Jedi until the fall of the Jedi Order, but they were exceedingly rare, and often passed down through generations.[source?] During the Galactic Civil War, the Galactic Empire banned trade and possession of all lightsaber focus crystals.[source?] No longer having Ilum crystals at their disposal, Jedi of the New Jedi Order settled for the use of various crystals and gems, creating lightsaber blades of multiple colors.

The synthetic crystals, favored by users of the dark side for their offensive properties, were filled with the negative energies of their creators, which gave the crystals their red color; the majority of the Sith and Dark Jedi wielded crimson-bladed lightsabers, though colors similar in hue to red, such as orange and magenta, were not unheard of.

Lightsaber crystals

"One of the other crucial pieces is a focusing crystal. The most powerful and sought-after gems are rare Kaiburr crystals. However, though lightsabers are powerful weapons, their design is so flexible that practically any kind of crystal can be used."
Luke Skywalker to his students on making a lightsaber[7]

There were a number of different stones, minerals and crystals that could be used in the construction of a lightsaber. Some jewels created different colors and effects in the lightsabers in which they were placed. Often, the rarer the crystal, the more powerful its effects on a lightsaber.[6]

Crystal colors

For millennia, the Jedi Order lit lightsabers in every color and hue imaginable. However, following the Battle of Ruusan, the hues of most available crystals had been limited to either blue or green. Lightsaber color crystals could also be compressed, resulting in a pulsating blade, or they could be unstable, resulting in a core which swirled and sparkled.

Lightsaber crystals of different hues could also be used in the same lightsaber to make a new blade color; for example, Galen Marek used Rahm Kota's green crystal along with his father's deep blue crystal to create an aqua blue blade.

Crystals could come in a variety of colors:

Blue crystals

Green crystals

Yellow and orange crystals

Red crystals

Purple crystals

Other crystals

Behind the scenes

"My sources say they're just younglings, headed back to the Jedi Temple from a training mission with the most important treasure in the universe—kyber crystals, used for making laser swords! The price for just one would make a man rich, and we all know how much I like to be rich, don't we?"
Hondo Ohnaka[13]

The earliest concept of the Kyber crystal, the "Kiber crystal", was conceived as a plot device in the second draft of the original Star Wars movie, similar to the Ring of Power in J. R. R. Tolkien's fantasy trilogy, The Lord of the Rings.[14] Crystals first appeared in the Star Wars material simply as an embedded decoration on the lightsaber hilt in the A New Hope novelization.[15] Aside from this single instance, there are no crystals mentioned in the original trilogy or its novelizations.[15][16][17]

Most crystals with special properties were from various video game and roleplaying-game sources. Since these special powers were often a function of game play, and not of the storyline, it is questionable if these powers are canon. However, since there are several examples of crystals with special powers in actual storylines (e.g. Lambent, Kaiburr, etc.), it is generally accepted that other crystals had special powers as well.

In Star Wars Galaxies, players must "tune" lightsaber crystals to themselves before they may use them in a lightsaber. Once tuned, the crystal can only be used by that player, and only in lightsabers created by that player.[10] In Star Wars: The Old Republic, players are able to gain lightsaber crystals to use with their lightsabers.[12]

"A Test of Strength," the seventh episode from the fifth season of the animated series Star Wars: The Clone Wars, first identified kyber crystals as a component of lightsaber construction.[13] Soon after, an article published on the StarWars.com Encyclopedia established that "kyber crystals" and "lightsaber crystals" were exchangeable terms.[18] This was later made even more evident with the Star Wars: Force and Destiny Core Rulebook, which identified several variety of crystals, such as ("Ilum crystal" or "Krayt dragon pearl") under the umbrella of "kyber crystals".[19]
