Diamond
IC2 Diamond is IndustrialCraft 2's diamond dust (ic2:diamond): the Macerator grinds a whole vanilla diamond into it irreversibly; its only consumer is Energium.

Description
IC2 Diamond is the diamond dust item that IndustrialCraft 2 registers under ic2:diamond. The catalog name says Diamond, but the item behaves as dust and pairs with Small Diamond Pieces from the same dust family. It is obtained by grinding one whole vanilla gem in the Macerator, a machine drawing 2 EU/t and spending 600 EU per operation. Nine Small Diamond Pieces crafted in a 3×3 grid work as the second route. The conversion is strictly one-way: dust cannot be smelted or crafted back into a gem. Mining never drops it — ore drops the vanilla gem instead.
Inside IC2's tech tree, IC2 Diamond has exactly one consumer: the Energium recipe. Four portions of the dust and five Redstone in a checkerboard yield nine Energium. Energium then feeds the Energy Crystal and the Glass Fibre Cable — the backbone of mid-tier EU storage and power transfer. High-tier recipes such as the Diamond Drill or Quantum Armor take whole vanilla gems instead, so grind only surplus stones into dust.

Guide
How to obtain and use IC2 Diamond
-
1
Stock whole vanilla diamonds
Mine vanilla Diamond Ore with an iron pickaxe or better — whole gems are the raw material IC2 Diamond is ground from.
-
2
Grind diamonds in the Macerator
Place a Macerator, power it at 2 EU/t, and feed it one diamond per 600 EU operation: each whole vanilla diamond yields exactly one IC2 Diamond.
-
3
Combine small piles
Alternatively, arrange nine Small Diamond Pieces in a 3×3 crafting grid — they compress into one IC2 Diamond.
-
4
Craft Energium
Combine four IC2 Diamond with five Redstone in a checkerboard pattern to produce nine Energium.
-
5
Spend it on power gear
Use the Energium to craft Energy Crystals and Glass Fibre Cables — IC2 Diamond itself has no other recipe.
One-way conversion
IC2 Diamond can never be turned back into a gem, and recipes like the Diamond Drill or Quantum Armor need whole vanilla diamonds — grind only the gems you can spare.

Frequently asked questions
Is IC2 Diamond the same item as a vanilla Minecraft diamond?
No. IC2 Diamond (ic2:diamond) is diamond dust: it does not substitute for a whole gem in any recipe, and Diamond Ore drops the vanilla gem, never the dust.
Can diamond dust be turned back into diamonds?
No. The IC2 wiki lists the conversion as strictly one-way — grinding is irreversible, so think twice before feeding your last diamonds into the Macerator.
What is IC2 Diamond used for?
Only the Energium recipe: four portions of diamond dust plus five Redstone in a checkerboard yield nine Energium, the basis for Energy Crystals and Glass Fibre Cables.
Do Diamond Drill or Quantum Armor recipes use IC2 Diamond?
No — those high-tier recipes consume whole vanilla diamonds, and grinding a gem into dust removes it from every tool recipe.
