Every Lightsaber Crystal Explained

The crystal at the heart of a lightsaber does more than focus energy. It amplifies it. That is what makes a fist-sized stone the difference between a torch and a weapon, and it is why kyber ended up powering both Jedi weapons and superweapons. This guide covers every named lightsaber crystal across Canon and Legends, just over sixty of them, sorted roughly from the weakest to the most powerful. For the weapons they were fitted into, see the companion guide to every lightsaber type and variant.

What lightsaber crystals actually do#

Lightsaber crystals were bound to the Force in something close to a symbiotic way, which is what let them do more than a lens does. They channelled energy, they focused it, and they amplified it. As Luke Skywalker told his students, the lightsaber design is flexible enough that practically any crystal will focus the beam. Some just do it far better than others, and a handful add powers of their own: more heat, faster reflexes, ionised wounds, invisibility.

Canon and Legends do not agree#

The two continuities handle crystals differently and it matters for everything below. In Canon a kyber crystal is clear until it is attuned. Once a wielder bonds with it, the crystal takes on one of the many lightsaber colours. In Legends the crystal already has its colour and the wielder picks one. Legends also splits into older and newer material that contradicts itself, and a large slice of the crystal list comes out of games such as Star Wars Galaxies and The Force Unleashed, where the powers get pretty wacky. One crystal freezes and burns a target at the same time. Treat the odder entries as Legends flavour rather than hard physics.

Training crystals: bondar and the weak Adegans#

Legends. The weakest crystals could not focus a blade properly, so instead of maiming or cutting, the weapon stung or stunned. That made them ideal for training lightsabers. Bondar crystals, found only in the far orbit of the Alderaan system, are the classic example. The weakest Adegan varieties served the same purpose.

The Dahgee crystal#

Legends. Worse than an ordinary kyber crystal, and one of the strangest looking. The Dahgee crystal produced a zigzagged blade, described as black and silver with a turquoise aura, though it is elsewhere recorded as green with a black core. The shape would have been genuinely inconvenient in a duel, which suggests it was closer to ceremonial. It looks incredible and would probably get you killed.

Ilum crystals#

Canon and Legends. The most abundant lightsaber crystal in the galaxy. Ilum was sacred to the Jedi Order and had been theirs for thousands of years, and so many Jedi took their crystal from that one world that plenty believed Ilum was the only source in existence. Ilum crystals had no special abilities at all. What they had was availability, consistent high quality and a strong affinity for the Force, which is exactly what an order arming thousands of Padawans needs.

Adegan crystals and their five subtypes#

Legends. Found mainly in the Adegas system, though also on Ilum and Mygeeto, and nowhere near as common as Ilum stone. Adegan crystals break into five subtypes. Kathracite, relacite and danite were the weakest, poor at focusing energy and good only for the stinging blade of a training saber. Mephite was the type the Jedi actually used, close enough in structure and quality to Ilum crystals that early Legends material made no distinction between them. Pontite was the rarest and the most interesting: cold to the touch, with some claiming the blade itself burned cold. What is documented is a calming aura, which helped light side users hold their connection steady in a fight.

Bleeding and purification#

Canon. Kyber crystals lean towards the light and will not bond with a dark sider, so the Sith take them by force. The wielder pours their hatred into the crystal until it turns red and corrupts. The process is reversible: Ahsoka Tano purified a pair of bled crystals and turned them white. Nothing has confirmed whether bled or purified crystals differ in raw power from an untouched one. When bleeding goes wrong the crystal cracks, producing the unstable, spitting blade Kylo Ren carried.

Synthetic crystals#

Legends. Same problem, different solution. Unable to obtain crystals that would work with them, the early Sith grew their own in giant forges using the dark side. Synthetic crystals produced a slightly more powerful blade than a standard kyber crystal and usually came out red, though they were not locked to the dark side. Luke Skywalker's second lightsaber ran a green synthetic crystal attuned to the light. On rare occasions the extra output was enough to short out an opposing lightsaber outright, which is a horrible thing to discover mid-duel. They were also versatile enough to be imbued with all sorts of effects, and unstable enough that many needed a crossguard or similar vent to bleed off excess energy.

Crystals bonded to a single owner#

Legends. A small group of crystals were no stronger than an Ilum stone but would only work for one person. Bondara's Folly, an unusually rare brown-bladed crystal, is one. Kenobi's Legacy is another. Bnar's Sacrifice, a one-off that also produced a brown blade, is a third. The lore never explains the mechanism, though the simplest reading is that the saber simply refuses to ignite for anyone else. Others were nastier. Bane's Heart, gifted by Darth Bane to his apprentice Darth Zannah, would light for a thief but discharge electricity through them, and that same crystal ended up in the weapon carried by NK-Necrosis, the reanimated corpse of General Grievous.

The absurdly expensive crystals#

Legends. Some crystals cost as much as a small planetoid. The Corusca gem refracts light so convincingly that it looks like a star is burning inside it, and Coruscant, originally called Notron, took its name from the way its city lights resembled corusca gems from orbit. The blade was stronger than standard, with Lando Calrissian reckoning it would go through transparisteel like a laser through jam.

Durindfire crystals produced a rare silvery white blade and were no more powerful than usual, but the Empire funded a chunk of the Death Star programme by selling them. The joke is that they were common, just only on Tatooine, where the Jawas used them to make the glowing red and yellow lenses covering their eyes. Nobody local knew what they were worth.

Ultima-pearls were silvery pearls dredged from the oceans of Dac, notoriously awkward to install, and the only confirmed use was by the Force-sensitive niece of Admiral Ackbar. The rainbow gem cost as much as a Mon Calamari cruiser and produced an elegant turquoise blade. The only other turquoise crystal on record is the one of a kind Sunrider's Destiny. Neither is known to grant a power beyond a strong attunement to the Force.

Krayt dragon pearls#

Canon and Legends. Gastroliths from the belly of a krayt dragon, swallowed as stones and slowly dissolved by digestive acid, exactly as birds and dinosaurs use gizzard stones. Occasionally one contained kyber. Killing a krayt to claim its pearl was treated as a major achievement by Tusken Raiders and monster hunters alike, as the second season of The Mandalorian showed. Pearls were notoriously difficult to fit into a lightsaber, but the blade that came out was powerful and howled when ignited.

Lambent crystals#

Legends. Yuuzhan Vong biotech rather than mineral, grown to help them take the galaxy. A lambent could bond telepathically with other creatures, and since its bearer could dim or brighten it at will, that made it a long-range signalling device. It also let whoever was bonded to it sense other Yuuzhan Vong nearby. Jacen Solo, later Darth Caedus, fitted a lambent to his lightsaber during the war and used it to feel out an enemy the Force could barely see.

Dantari crystals#

Canon and Legends. The Jedi's main crystal source before Ilum, found on Dantooine, sometimes inside the eggs of the cave-dwelling kinrath, and nobody ever worked out how they got there. Like Canon kyber they shifted colour according to the wielder's alignment, and could turn up in almost any hue, most often red, blue or green. They carried a bonus a standard crystal does not: during a fight a Dantari crystal recycled the fury of battle, letting the wielder replenish their Force reserves far faster. The purple crystal in Revan's lightsaber is believed to have been one.

Hurrikaine crystals#

Legends. Deep blue to violet, found only on the planet Hurikane and gathered by a stone-encrusted native species. Mace Windu travelled there as a Padawan after receiving visions of the crystal, was confronted by the natives, and harmed one of them with a Force repulse. Realising what he had done, he used Force healing to repair the being. In return he was given a handful of the rare amethyst crystals that went into his electrum lightsaber. Blades made with them were unusually good at quickening reflexes and punching through an opponent's guard.

Ionising crystals: luxum and firkrann#

Legends. Luxum crystals formed from the dark energies of Ambria and gave the blade ionising properties, so anything struck also took an electric shock. Handy if you spend the Clone Wars hacking apart battle droids. The Firkrann crystal did much the same thing, slightly harder, but only worked for dark siders. Its most famous owner was Tulak Hord, the Lord of Hate.

Black crystals#

Canon and Legends. The crystal inside the Darksaber is a genuine unknown. Nothing records where it came from or why the blade is black. There is a long-running argument over whether the Darksaber cuts better than a standard weapon, and if it does, whether that comes from the crystal or the flattened sword profile.

The other black blade is the Blackwing crystal. Project Blackwing was an attempt to beat death using science, Sith alchemy and the dark side. It worked, technically, in that the virus granted immortality while turning its victims into slaves of a hive mind. The infection spread to living things and to the semi-living kyber crystals as well. When the virus escaped again during the Imperial era, crystals inside the Dathomir quarantine zone turned black. Fitted to a lightsaber they threw a black blade with smoke pouring from the hilt. Whether the weapon gained any real ability is unrecorded, though the crystal could probably carry the infection onward.

Lorrdian gemstones#

Legends. A synthetic crystal originally produced by the Lorrdians, an enslaved people forbidden from speaking who developed the gems as a kinetic communication aid, reading tiny shifts in posture, mood and body language. Force-sensitives among them eventually imbued the stones with the Force. Anyone wielding one understood an opponent's movement far better than they should have, which made it a strongly defensive crystal.

Crystals that change the blade's shape#

Legends. Damind crystals were dark side stones favoured by physically large Sith, because they substantially increased the length and girth of the blade in the same way the great lightsaber did. That also made them popular with defensive form users, since a fatter blade is easier to deflect blaster bolts with. Pulling the other way, velmorite crystals produced a thin, fluid blade admired for its grace, and rubat crystals focused the blade down to a sharp point for precise strikes. Rubat was popular in the early days of the Jedi Order, before Ilum, and stayed admired long into the post-Imperial era for the focus, agility and speed it lent its wielder.

Focus crystals#

Legends. A whole subgroup associated with the light side, all of them sharpening the mind rather than the blade. The most famous is the Solari crystal, an orange-bladed stone said to be among the oldest in the galaxy, dating to the beginning of the Jedi Order. It came with a catch: waver from the light for a moment and the blade goes out, so only Jedi of genuinely clean conscience could rely on one.

The Kasha crystal was used by Cerean meditation practice, the species Ki-Adi-Mundi belongs to, and the Cereans found a way to sharpen it further by scribing patterns into the stone with the Force so it focused more cleanly. Blades built with one instilled a meditative calm in the middle of a fight. Meditation crystals grew naturally on Tython, the Jedi homeworld, and did something similar plus one extra trick: every time the blade struck an opponent, spent Force energy came back, which is exactly what you want in a long, grinding duel.

Crystals that make the blade hotter#

Legends. A cluster of crystals raised the heat and intensity of the blade, usually through the dark side, occasionally through natural attunement to the light. Nextor crystals were among the most volatile, granting real power at real risk to the wielder.

Exar Kun's crystal sits at the top of this group. His lightsaber was heavily worked with dark side alchemy that drove the blade's heat so far up it went through Mandalorian beskar armour like paper. It may well have been a Lignan crystal, a rare stone that sharply increases blade heat and, through its dark side link, feeds the wielder's own Sith abilities. Naturally occurring crystals of the same family came in far weaker. Sigil and Phond crystals raised the temperature noticeably less, and ancient Jedi still went to considerable lengths to get hold of one.

The Qixoni crystal was forged in an exploding supernova, which loaded it with enormous energy. That pushed both the potency and the heat of the blade and increased its Force potential, so the wielder could amplify their own power through it. The Sapith crystal has a humbler origin, being produced by the sapith worm, and yields a blade that is both stronger than standard and easier to control. Opila crystals also raised heat; refined and cleaned they became Jenruax crystals, which added agility on top, something like the Force speed on show in The Phantom Menace.

Barab ingots came off the irradiated world of Barab I, where the radiation fundamentally altered the stone. The blade usually came out clear, but the sheer energy pouring off it stopped the plasma from holding cohesion, so it burned more like fire than a blade. Anyone struck with it caught alight immediately.

Compressed energy crystals#

Legends. A variation on the synthetic crystal, producing blades that were thinner than standard and visibly pulsed, usually with a power attached. The incineration crystal used by Starkiller is the best known, and it caused victims to spontaneously combust. The corrosion crystal produced a blade so reactive with flesh that a wound corroded away as though the body had been dipped in acid.

Crystals that burn cold#

Legends. A small, strange family that includes Kenobi's Legacy, Baas' Wisdom and the permafrost crystal. They cut about as well as an ordinary blade and produce plenty of heat, but they also absorb thermal energy out of whatever they hit, leaving parts of the wound frozen with frostbite. So the same strike burns and freezes at once. The lore does not explain how that works, and being sliced, scorched and frozen simultaneously sounds like an appalling way to go.

The Ankarres Sapphire#

Legends. A legendary crystal heavily attuned to the light, and hostile enough to the dark side that any dark sider who touched it reportedly suffered third degree burns. In a fight it strengthened the wielder's connection to the light and bolstered their courage and focus, and it substantially boosted Force healing, letting the user close wounds on themselves and others.

The Dathomir crystals#

Legends. The Witches of Dathomir were founded by Allya, a Jedi exiled to the planet around 600 BBY, who taught the local Dathomiri the more mystical corners of the Force along with how to ride rancors. Two crystals are credited to her. Allya's Exile produced an intensely hot scarlet blade, probably the hottest of any crystal here, throwing off enough heat to burn an opponent from a short distance without the blade ever touching them. Allya's Redemption was imbued with Nightsister magic, so anyone cut with it suffered the heat, a corrosive acidic effect, and then a venom that consumed them slowly. Even a shallow wound could kill.

The Vexxtal crystal#

Legends. A dark side crystal from The Force Unleashed, imbued with the little-known dark side power of Force plague. Even a minor cut from a Vexxtal blade tended to be fatal. The wound became infected with a dark side disease that behaved like a fast-acting toxin, draining the victim and clouding their mind. Without immediate attention from a powerful Force healer, it finished the job.

Amplification crystals#

Legends. Among the most useful crystals in Star Wars, because they were used alongside another crystal and multiplied whatever it already did. Pair one with a Vexxtal and the plague gets worse; pair one with an ordinary crystal and the heat climbs sharply. They produced a distinctive silver blade, one of very few. The best known user was Maulkiller, the dark side abomination Darth Vader built as a perfect assassin from the DNA of Darth Maul and Starkiller. The mismatch between the two templates eventually drove him insane.

The Heart of the Guardian and the Mantle of the Force#

Legends. Two ancient crystals that also boosted whatever else was in the hilt. The Heart of the Guardian is tied to the founding of both the Jedi and the Sith. The Jedi held that in their darkest hour it would resurface and bring salvation; the Sith held that its reappearance would mean their domination of the galaxy. Fittingly, it was most likely used by Revan, who was both. On top of amplification it sharply increased the wielder's speed.

The Mantle of the Force was the other crystal Revan hunted, with much the same amplifying property and one advantage. It also strengthened the wielder's own connection to the Force, letting them fight harder and for longer.

Concussive crystals: dragite, etaan and impact#

Legends. Dragite crystals produced an ordinary-looking blade with a deafening roar instead of a hum. When a dragite blade struck another lightsaber it generated a small sonic boom strong enough to injure an opponent or knock the weapon out of their hands. It could also injure the wielder, so it needed handling with care. Etaan crystals did something similar with heat and kinetic energy rather than sound, and carried a bonus on blaster deflection: the returning bolt came back charged, exploding on impact.

The impact crystal, a compressed energy crystal that Galen Marek used to good effect, produced yellow blades and turned the weapon into something closer to a baseball bat. That mattered against armour. A Mandalorian in beskar might shrug off the blade itself, but not the concussive force behind it, which could still wreck organs or circuitry through the plate.

The lava crystal#

Legends. Found only in the deepest parts of volcanic worlds, and it changes what the blade actually is. Instead of near-weightless plasma you get something heavy and dense with the consistency of lava, throwing off fire and flinging molten fragments as it moves. The weight and the spatter made it dangerous to its own wielder. Only heavily augmented figures such as Vader could realistically manage one, and even he preferred a normal blade.

Invisible blades: eralam and ghostfire#

Legends and Canon. Eralam crystals, from the world of the same name, produced no coloured plasma at all. The blade came out completely transparent, which is why it gets called the invisible lightsaber. The tactical value is obvious, and it would be brutal in a curved or double-bladed hilt.

The ghostfire crystal goes further. Entirely transparent itself, growing as near-invisible spires on Outer Rim mountain peaks, it produced a blade that was dim, translucent and almost silent, and it left illusory afterimages trailing behind the strike. Working out where the blade actually is becomes close to impossible. In the hands of a competent duellist that makes it one of the most dangerous crystals on this list.

The Katak crystal#

Legends. A dark side crystal of unknown origin whose energies gave the blade the Force drain ability most associated with Darth Nihilus. The wielder slowly pulled the life force out of everyone nearby, using it to close their own wounds and top up their energy. The drain was eventually fatal, though it took a long time to finish.

Stygium crystals#

Legends. Powerful enough that the Galactic Republic banned them. Stygium crystals warped perception around themselves, effectively making the user invisible to the naked eye and to scanners alike, and the effect stacked with the Force stealth ability. The same crystals cloaked starships and other advanced hardware, including the Phantom TIE project, Maul's Scimitar and Starkiller's Rogue Shadow. They saw heavy use early in the Republic, caused enough trouble to be outlawed, and were technically among the most common crystals in the galaxy. When the Imperial superweapon Tarkin cracked open the planet Aeten II, the entire core turned out to be Stygium. At least one invisible island made of the stuff also existed. Abundant they may have been, but being invisible made them nearly impossible to find and mine.

The Kaiburr crystal#

Legends. The most powerful lightsaber crystal there is. An ancient relic created by some kind of powerful Force being, most likely a Celestial, and Luke Skywalker believed nothing outclassed it. A tiny sliver of it noticeably raised a Force user's potential. Whoever held the whole crystal got something far more dramatic: inside a Force nexus it could amplify its bearer a thousandfold. That is the crystal that let Vader use kinetite, a variant of Force lightning, without frying his own life support. Carry it away from the nexus and the power drops off sharply, and it is still regarded as the finest lightsaber crystal in the galaxy.
