Raw crystal comes in six grades in Star Trek Fleet Command, and the 3★ and 4★ grades are the ones most players are looking for. 3★ crystal is mined in 32 systems: 24 in open space, starting with Francihk and Antonehk (level 20 and 21, warp 13) in Klingon space, plus 8 Territory systems. 4★ crystal is in 24 systems: 16 in open space from level 40 and warp 56, with Nikola and Sadell the closest, plus 8 Territory systems. Each table runs from the lowest warp up, so the easiest systems come first.

Raw crystal is one of the three graded raw materials, alongside ore and gas. Plenty of resources get refined (latinum and isogenite among them), but ore, gas and crystal share the same star-grade pattern: you mine them in grades and refine each grade into the materials your ships consume. Crystal skews toward Klingon space from 3★ upward, which shapes where you mine it.
Why you need crystal
Refined crystal is a building block for ship upgrades all through the game. 2★ refined crystal upgrades 2★ interceptors, and from 3★ upward each grade of refined crystal upgrades ships of that grade. It tends to be the material players run short on when pushing interceptors. Raw crystal is worthless until refined, so your refinery level decides how high a grade is worth mining.
How crystal grades and refining work
Each grade refines into a band of materials: 2★ crystal into Common and Uncommon, 3★ into Common, Uncommon and Rare, and 4★ into the higher tiers. Refining unlocks by level: 3★ materials from Ops 20, and 4★ from Refinery level 39. Mine the highest grade your refinery can process; anything higher just stockpiles as raw material you cannot use yet. In open space 5★ crystal starts at system level 50, 6★ at 61 and 7★ at 71, and Territory systems carry some of each grade.
How to get crystal
- Mining is the main source, and from 3★ up it is concentrated in Klingon space. Systems are below.
- Refining is the required second step. Raw crystal is inventory until it goes through the refinery.
- Daily goals and events: mining events pay raw crystal, and refining events pay the finished materials.
- Some hostiles drop raw crystal with the rest of their loot.
Like ore and gas, crystal cannot be raided from a station. It is only at risk on a loaded mining ship destroyed in space, so protection matters most while you are parked on a node.
2★ crystal locations (G2)
Seven neutral systems hold 2★ raw crystal, between system level 12 and 21 and warp 8 to 15. Bellas and Nelve (level 12, warp 8) are the lowest-warp crystal in the game, with 5,500 nodes. Astrida and Lycia (level 14, warp 12) carry 15,000 and 25,000 nodes, and Fastolf (level 21, warp 15) has the largest 2★ crystal nodes.

3★ crystal locations (G3)
3★ crystal is Klingon territory: 16 of the 24 open-space systems are Klingon. Francihk (level 20, warp 13) and Antonehk (level 21, warp 13) are the first stops. Node sizes grow with level, from 3,600 at level 20 to 60,000 in Lankal, Katovug, Archanis and YoDSutlj NaQ, and 90,000 in Ty’Gokor (level 39, warp 53). Two systems need an item to enter. Perek (level 24, warp 20) takes a Lucrative 3★ Mines Transwarp Cell and holds a single 1,000,000 node that also mines far faster than a normal 3★ node, and Van Cleef (level 29, warp 24) in Rogue space takes a Rogue Transwarp Cell.

4★ crystal locations (G4)
All 16 open-space 4★ crystal systems are level 40 or higher, so warp range is the gate. Nikola (level 41, warp 56, two nodes) is the nearest, then Sadell (level 40, warp 58), the only one outside deep space and a 400,000 node. Garyb, Veringan and Zlim’kach (level 40, warp 65) follow with 100,000 nodes. Maht-H’A, Stambo and Dohrmas (level 44 to 46) carry 400,000 nodes, and Muhg, Padilac, Petandria and Inoss (level 48 to 50) carry 2,400,000.
Callinon, a level 43 Dominion system at warp 75, takes a G4 Dominion Transwarp Cell and holds one 5,000,000 node with a much higher mining rate than normal 4★ nodes. Aethera Nova and Orinthus Prime take a Silent Nebula Token.

5★ crystal locations (G5)
5★ crystal opens at system level 50 with ghuH and tIn jIb (warp 185) in Klingon space. The 15 open-space systems reach warp 525, and node sizes climb from 1,000,000 to 3,000,000 in Ovelya (level 59, warp 500). Neken (level 51, warp 205) is the only one outside deep space. Idraan (level 55, warp 240) is the Dominion system for this grade: it takes a G5 Dominion Transwarp Cell and has one 60,000,000 node. Valtara Minor, Lyrae Nebula and Sylphira Delta take a Silent Nebula Token.

Best crystal mining crew
Crystal crews split the same way every mining crew does, by whether your server allows OPC (over protected cargo) hits on parked miners.
- If miners are safe, crew for speed. Barot as captain raises the crystal mining rate, and Eleven of Eleven is the alternative captain with Efficient Crystal Acquisition. On the bridge, Two of Eleven (Extraction Protocol raises crystal, gas and ore mining) and Ten of Eleven (raises the ship’s mining speed) are the strongest pair, with Stonn as a swap when you need more cargo room. Shran below decks adds crystal mining speed.
- If OPC hits are allowed, crew for protection. Joaquin as captain with T’Pring and One of Eleven keeps the most cargo safe, and it matters more on 3★ crystal, since the Klingon-space nodes draw crowds.
- For 3★ crystal specifically, Raphaël DuPont as captain raises G3 crystal, gas and ore mining.
Fill the rest of the bridge with Surveyors and Miners officers for the synergy bonus. For current rankings, see the officer tier list.
Best ships to mine crystal
The crystal specialists are the Klingon K’Vort and the Klingon B’Chor, both with abilities that raise their crystal mining rate. The Mow’ga and Grishnar carry crystal mining rate bonuses as well, and the Selkie raises crystal, gas and ore mining together. Any strong survey ship works when its cargo hold is the biggest you have, since at higher grades the hold becomes the limit before the node does.
Crystal FAQ
Where is the closest 4★ crystal?
Nikola (level 41, warp 56) and Sadell (level 40, warp 58) in open space. Eight level 20 Territory systems also hold 4★ crystal, which sit in Territory Capture space.
Where is 3★ crystal most common?
Klingon space. Francihk and Antonehk (warp 13) are the first 3★ stops, and Enthra, Pekka and Lixar carry bigger nodes further in.
What is the difference between the crystal grades?
Higher grades refine into higher-tier materials: 2★ gives Common and Uncommon, 3★ adds Rare, and 4★ and up feed the late-game tiers. Mine the highest grade your refinery level can process.
When can I refine 3★ and 4★ crystal?
3★ materials from Ops 20, and 4★ from Refinery level 39. Below those levels the raw crystal just sits in your inventory.
Can other players steal my crystal?
Not from your station, because raids only take parsteel, tritanium and dilithium. Crystal is only at risk on a loaded miner destroyed in space, so crew for protection when you park.
