How to Spot Precious Ores in Dark Caves

Jays Ores Mod adds a visual shimmer effect to valuable blocks, making it much easier to spot rare treasures while exploring unlit caves or digging through dark dimensions.

Which Blocks Shimmer

The visual shimmer applies to both newly added mod resources and select vanilla treasures:

• Mod Gemstones and Precious Ores: Shiny gemstone ores (such as onyx, ruby, sapphire, garnet, and jade) and rare metal ores will glint in the dark, as do their crafted gemstone storage blocks.
• Vanilla Ores: Vanilla gold ore and diamond ore also receive this visual shimmer effect.

Caving Without Torches

Because precious ores stand out visually in low light, you can adjust how you explore large caves:

1. Enter a dark ravine, deep cavern, or Nether basalt biome before placing down torches.

2. Pause and scan the dark walls, ceilings, and floors for the telltale shimmering effect.

3. Follow the glint to reach high-value veins—such as diamonds in the Overworld or rubies and sapphires embedded in dark Nether basalt—that you might otherwise walk past.

4. Keep in mind that common base metals like tin or aluminum may blend into the stone more than precious ores, so you should still light up caves once you have checked the darkness for shimmering highlights.
