Resonant Crystal is the top rung of the crystal ladder in Ala Industrial, an HV crafting material for Minecraft 26.2 Java Edition that no crafting table assembles directly. The crafting table yields only the Resonant Crystal Blank: a finished Lapotron Crystal in the centre, Resonant Shards in the four corners, Spatial Crystals on the sides and an Energy Clot III below the middle. The blank then absorbs 1 500 000 EU in any charge slot at up to 128 EU/t (1/20 of a second per tick) — no charger in Ala Industrial fills faster — and once the buffer is full the blank is replaced by the finished crystal. The finished Resonant Crystal carries no energy at all: no charge bar and no buffer, because the 1 500 000 EU were the price of making the crystal, not its contents. Ala Industrial runs on both Fabric and NeoForge, and the blank charges in a Battery Box slot, in a CESU, on a Charging Station, in a worn Energy Pack or even in another mod's charger.

Resonant Crystal serves exactly one recipe: two Workstations from a single craft — glass panes and the crystal on top, Resonance Coils around a Reactor Control Circuit, Reinforced Bearings and an Advanced Machine Casing below. The ladder cannot be skipped: the Energy Crystal takes 100 000 EU, the Lapotron Crystal takes 500 000 EU, and each blank is built around the finished crystal of the previous rung, so Resonant Crystal demands a fully charged Lapotron Crystal plus another 1 500 000 EU. A CESU feeds 128 EU/t, so the final charge takes about 9 minutes 45 seconds — drop the blank into the slot and build something else meanwhile. Ala Industrial exists only for Java Edition, and the mod has no Bedrock version of the crystal.
