for Minecraft, Corundum (formerly Cave Crystals) is a unique decorative and functional block that can be farmed infinitely once you find a starting "seed" block. Finding Corundum : Naturally spawns in non-ocean caves above
. They often appear in pairs of colors (e.g., blue and yellow) and emit sparkling particles when you are nearby.
: Can be difficult to find; some players suggest searching inland or in Diorite caves. They can also occasionally be found in Atum Pyramid Farming Mechanics
Corundum grows naturally under specific conditions, allowing you to set up a "crystal farm": Depth Requirement : Corundum only grows when placed at Growth Height : It grows in a vertical column up to 4 blocks high Growth Indicator
: When a Corundum block is capable of growing, it will release small particles. Manual vs. Auto
: You can simply place a block deep underground and wait for it to grow upward, then harvest the top blocks with a pickaxe, leaving the base to regrow. Practical Uses
: Used to craft Runes, which apply a colored "sheen" or glow effect to your enchanted tools and armor. Decoration
In the context of the popular Minecraft mod , a "Corundum Farm" refers to an automated or semi-automated system designed to cultivate and harvest Corundum Clusters
. Corundum is a glowing crystal that generates deep underground and is primarily used for decorative lighting or changing enchantment colors using Runes. Core Farming Mechanics
Corundum has unique growth properties that distinguish it from other resources like Amethyst: Vertical Growth
: If a Corundum block is placed at a low Y-level (typically below ), it will grow vertically into a pillar up to 4 blocks high Cluster Generation
: Small crystal clusters will spontaneously grow on the sides of these pillars. Particle Indicators
: Blocks capable of growth will emit sparkling particles in the cave environment. Step-by-Step Farming Guide
To establish a functional farm, follow these procedures based on community best practices: Acquisition
: Find naturally occurring Corundum in underground caves, often appearing in pairs of colors (e.g., Blue and Yellow). A Nature's Compass
can help locate biomes like "Shield" or "Diorite Caves" where they are more common.
: Transport the blocks to a deep subterranean chamber. While they can grow anywhere deep, keeping them in their native depth range (Deepslate level) ensures growth. quark corundum farm
: Arrange the blocks in a staggered formation. Because clusters grow on the sides of the pillars, placing blocks too close together can block growth. Harvesting
: Use a pickaxe to break the clusters and the extra pillar blocks. Automation
: Since Quark allows pistons to move most "tile entities" and blocks, you can use Piston-based harvesters or automated breaking machines from other mods (like
) to harvest the pillars once they reach their maximum height. Key Uses of Farmed Corundum Rainbow Lamps
: Powered by Redstone, these lamps change color based on the type of Corundum used. Enchantment Runes
: Corundum is a key ingredient for crafting Runes, which change the color of the "glow" on enchanted items. Beacon Coloring
: Powered Rainbow Lamps can be used to color beacon beams dynamically. for a fully automated harvester?
The Ultimate Guide to Quark Corundum Farming in Minecraft If you’re running a modded Minecraft instance with Quark, you’ve likely stumbled upon the vibrant, crystal-like clusters known as Corundum. These blocks aren't just eye candy; they are a unique light source and a vital component for redstone engineering and aesthetic building.
Unlike standard ores, Corundum grows. This means you can move beyond manual mining and set up a fully automated Quark Corundum farm. Here is everything you need to know to get your crystal empire running. What is Corundum?
Corundum is a translucent, glowing crystal added by the Quark mod. It comes in several colors (Red, Orange, Yellow, Green, Blue, Indigo, Violet, and White) and is found deep underground, typically near bedrock. Key Properties: Luminance: It emits a high light level.
Growth: When placed on top of a Corundum Cluster of the same color, it can grow upwards.
Redstone: Waxed Corundum can be used to create "Redstone Crystals," which act as vertical redstone wires. The Mechanics of Growth
To farm Corundum effectively, you have to understand its growth stages. Corundum starts as a Cluster (the base block). Over time, if there is air above it, a Corundum block will sprout. If that block is left undisturbed, it can grow up to four blocks high.
The Golden Rule: You cannot "plant" Corundum on dirt or stone. It must be attached to a Corundum Cluster block. Designing a Manual Corundum Farm
If you’re early in your playthrough, a manual farm is the easiest way to start.
Locate Crystals: Find a natural Corundum deposit in a deep cave. for Minecraft, Corundum (formerly Cave Crystals) is a
Clear Space: Mine the surrounding stone to create a room. Leave the bottom-most "Cluster" blocks intact.
Light and Access: Ensure you have enough space to walk between rows.
Harvesting: Use a pickaxe to break the grown crystals. Do not break the base Cluster block unless you have Silk Touch and want to move the farm to your base. How to Build an Automated Corundum Farm
To truly master the mod, you’ll want an automated setup. Since Corundum behaves similarly to Sugarcane or Bamboo (growing upwards), we can use Observers and Pistons. Materials Needed: Corundum Clusters (Base blocks) Redstone Dust Hopper & Chest (for collection) Water buckets (for a collection stream) Step-by-Step Instructions:
The Base: Place your Corundum Clusters in a straight line. Dig a trench in front of them and fill it with flowing water leading to a hopper.
The Piston Layer: Place a solid block behind the Clusters. On top of that block, place a Piston facing the area where the crystal will grow (usually at the second-block height).
The Observer Layer: Place an Observer on top of the piston, facing the crystal path.
The Circuit: Place a solid block behind the piston and a piece of redstone dust on top of that block. This connects the Observer to the Piston.
The Result: When the Corundum grows to the height of the Observer (3 blocks high), the Observer sends a signal, the Piston fires, and the Corundum is broken and pushed into the water stream. Pro Tips for Maximum Efficiency 1. Use Silk Touch
If you want to move your farm to the surface or your main base, you must use a Silk Touch pickaxe to harvest the Clusters. Breaking a Cluster with a regular pickaxe only drops shards, which cannot be used for farming. 2. Biome and Depth
While Corundum naturally generates deep underground, once you have the Clusters, they will grow anywhere—even in the Nether or the End. 3. Color Coordination
Since each color of Corundum only grows on its matching Cluster, you can create a rainbow-themed room where each row produces a different color. This is perfect for players who use Corundum for specific Redstone Crystal logic. 4. Waxing for Redstone
If you are farming Corundum for redstone use, remember to combine the harvested blocks with Honeycomb to create Waxed Corundum. This prevents it from growing further or changing state, making it a stable component for your machines. Conclusion
A Quark Corundum farm is one of the most visually satisfying projects in modded Minecraft. Whether you need the crystals for their vertical redstone capabilities or you just want to build a glowing, neon cathedral, automating the process saves you hours of cave-diving.
Set up your Observers, protect your Clusters, and start harvesting the glow!
In the Quark mod for Minecraft, Corundum is a unique crystal found deep underground that possesses a rare property: it can grow. Unlike most blocks, Corundum crystals can slowly regenerate and grow into pillars, making it possible to create a self-sustaining renewable farm for these colorful decorative blocks. How Corundum Grows The Best Locations for Quark Corundum Farm If
To farm Corundum, you must first understand its natural growth mechanics:
Depth Requirement: Corundum only grows when placed at Y level 24 or lower. If placed higher, it remains static and will not produce new blocks.
Pillar Formation: A single Corundum block will slowly grow upwards in a column, reaching a maximum height of four blocks.
Visual Cues: When a Corundum block is capable of growing, it emits small sparkling particles. If you "wax" the block (using honeycombs), it stops producing particles and ceases growth, which is useful for permanent decorations.
Crystal Clusters: In addition to full blocks, small crystal clusters can also sprout on the sides or top of the main Corundum pillar. Setting Up Your Farm
Building a basic Corundum farm is straightforward once you have found your first few blocks in deep caves:
Location: Dig down to Y=0 or lower to ensure optimal growth conditions.
Layout: Place your seed Corundum blocks on the floor with at least three blocks of air above them to allow the pillar to reach its full height of four.
Automation (Optional): While growth is notoriously slow, you can automate the harvest using other mods like Create. Mechanical pistons or drills can be timed to break the top three blocks of a pillar once it reaches its maximum height, leaving the base "seed" block to start the process over.
Efficiency: Since growth is random and slow, expanding the footprint of your farm (planting dozens of seed blocks) is the best way to ensure a steady supply of crystals. Finding Your First Crystals
You cannot craft Corundum; you must find it in the wild first. Look for large, glowing patches in deep caves, often found in pairs of colors like blue and yellow or white and green. Some players suggest searching specifically under mountain biomes or using a Nature's Compass to find diorite caves, where openings are often larger and easier to explore.

If you simply open the "Dungeons" tab, you won't see "Quark Farm" listed. You have to read the fine print. The drop rates vary significantly by dungeon tier.
Quark allows corundum to grow on basalt when exposed to certain conditions. This farm exploits:
Observer → Repeater (2 ticks) → Redstone to piston.
When corundum grows, piston extends, breaks the gem, retracts.
Put a hopper below the basalt to collect drops. Hopper → Chest.
Do not waste time checking every rock. Quark Corundum spawns exclusively on specific base textures:
