Find diamonds in Solarpunk by reaching the Frozen Islands, powering a drill on a diamond node, and setting up drones to keep your late-game mine running.
In Solarpunk, diamonds are the resource you chase once your starter base is humming, and they don’t show up anywhere near where you began. Reaching them means flying your airship out to a cold, snow-covered island cluster on the far edge of the map, dropping mining machines on the deposit, and setting up drones to carry the haul back. This guide walks through where that biome sits, how to reach it, and how to keep the mine running once you’re there.
Diamonds in Solarpunk are a late-game resource found only on the snowy winter islands (the Frozen Islands), where you place a powered drill on a diamond node to turn it into a continuously-mining diamond mine.
Where diamonds actually spawn in Solarpunk
Diamonds live on the far-out winter islands — a snow-covered cluster that players also call the Frozen Islands or Frozen Isles. It sits well past your home base and the vendor, deep on the edge of the map, and it is the only place diamonds turn up. The starter island only has iron ore, so if you’re hunting diamonds there, you’re on the wrong landmass entirely.
Getting your airship ready for the trip
Diamonds are an end-of-the-line target, and the work to reach them is really airship progression. You start by mining iron ore on the starting island near the tiny lake, smelt ore through a furnace, then build an airship dock and airship so you can leave the early islands at all. From there it’s a copper grind: gather enough to buy the airship’s upgrades through the trader until it can fly far enough to reach the late-game islands.
| Step / unlock | What it costs or needs |
|---|---|
| Furnace unlock (research table) | 3 stones |
| Furnace build | 15 stones |
| Basic pickaxe | 2 sticks + 3 stones |
| Airship level-two upgrade (via trader) | 32 copper |
| Airship level three | Benchmark for reaching far-map islands |
Carry spare pickaxe components on the trip — mining chews through durability fast, and a basic pickaxe is cheap to replace at 2 sticks and 3 stones if it breaks mid-run.
How to set up a diamond mine in Solarpunk
Fly out to the winter islands
The diamond node sits on one of the far-out winter islands, well past your home base and the vendor.
Place mining machines on the node
Drop drills directly onto the diamond deposit — two machines working the same node keeps output up.
Assign the machines to a drone
Make sure each drill is assigned to a drone so the diamonds get carried back to base instead of piling up.
Add more drones to scale the haul
The drills don’t run constantly and one drone can’t service everything, so add drones to collect more than one drill’s worth at a time.
Power the mine for overnight running
Bring a windmill, or a battery if you’re running solar panels, so the mine keeps producing all night.
Bring a windmill (or a battery if you’re on solar) so the mine keeps drilling overnight instead of stalling the moment your panels lose the sun.
What diamonds unlock at end game
Diamonds feed the end-game crafting tier. They’re what you need for the top-end tools — the diamond axe, diamond pickaxe, diamond hoe and the rest of the late-game kit. That’s the whole reason the long airship climb pays off: nothing earlier on the map gets you these, and the full recipe list isn’t laid out in detail, so expect them to gate the best gear in the game.
Mistakes that waste a Frozen Islands run
The biggest one is searching the wrong biome. Plenty of players comb the starter and temperate islands for diamonds, but that ground only yields iron ore — diamonds are exclusively on the winter / Frozen Islands.
Once you’re actually mining, two practical things trip people up. Forgetting power is the killer — a drill with no power pole or connection simply won’t run, and if you’re on solar without a battery it’ll die every night. And under-provisioning drones means diamonds stack up faster than they’re carried home; because each drone only services so much and the drills don’t run continuously, scaling output really means scaling drones. Set up a windmill or battery, run more than one drone, and the remote mine will feed your base while you’re off doing something else.
Frequently Asked Questions
What are diamonds used for in Solarpunk?
Diamonds are an end-game crafting material, used for the top-tier tools such as the diamond axe, diamond pickaxe and diamond hoe, along with other end-game gear.
Can you mine diamond with a basic pickaxe, or do you need a better tool?
Bring your best pickaxe and spare components to be safe.
How many drones do you need to collect from the diamond mine?
More than one. The drills don’t run all the time and a single drone can’t service everything, so to pick up more than one drill’s worth of diamonds at a time you’ll want multiple drones assigned to the mine.
Is there more than one diamond node on the winter islands?
That’s not confirmed. Typically there is a single main diamond node, and whether world seeds can generate more isn’t verified — plan around finding one rich deposit.
What is the Shiny achievement and how do you unlock it?
The Shiny achievement is tied to obtaining diamond, so reaching the winter islands and mining the node is what’s involved.
So, diamond mining for weddings? That’s a unique angle. How do you even start that process?
