Looking for how to get Type Gems in Cobblemon? In Cobblemon 1.8, Type Gems went from niche held items to a core crafting resource — especially for the new TM Machine. This guide covers every way to obtain them, the best Type Gem farm setup with Deepslate Crystal Cores, mining yields, Alpha drops, ruin loot, and what people mean when they search for a Cobblemon Type Gem recipe.

There is one Type Gem for every Pokémon type (Normal, Fire, Water, Grass, Electric, Ice, Fighting, Poison, Ground, Flying, Psychic, Bug, Rock, Ghost, Dragon, Dark, Steel, and Fairy). Once you know where they grow and how Crystal Cores work, you can farm the exact types you need for TMs.

What are Type Gems in Cobblemon?

Type Gems are type-colored crystal items. Their main job in Cobblemon 1.8 is powering TM crafting at the TM Machine, but they also work as held items and can be compacted into storage blocks.

• TM production — primary ingredient when crafting unlocked TMs.
• Held item — boosts the next move of that gem's type by 10%, then is consumed.
• Storage / décor — craft gems into Type Gem Blocks, or use gems in wool-and-string held item crafts.

Type Gems were added earlier, but Cobblemon 1.8 made them far more important by adding natural underground crystal formations and tying them tightly into the craftable TM system.

All the ways to get Type Gems

If you are searching how to get Type Gems in Cobblemon, these are the four sources that matter:

Where Type Gems spawn underground

In Cobblemon 1.8, Type Gems generate as exposed crystal formations in Deepslate caves throughout the Overworld — similar in vibe to amethyst geodes, but type-colored and built around a special core block.

Each natural formation includes:

• A Deepslate Crystal Core in the center
• Connected growth stages of one randomly selected Type Gem (buds, clusters, and eventually Type Gem Blocks)

Bring an Iron Pickaxe or better. Type Gem stages and the Crystal Core both require iron-tier tools to collect properly. When you find a formation you like, mine the core carefully so you can rebuild the farm at your base instead of commuting to the cave forever.

Type Gem growth stages and mining yields

Crystal growth works a lot like amethyst. Formations progress through: Small Bud → Medium Bud → Large Bud → Cluster, and clusters can blossom into Type Gem Blocks that grow their own buds.

Harvest timing matters. Small buds give nothing; clusters and blocks are where the real gem count is. Use Fortune on buds/clusters for better rolls (blocks do not scale with Fortune the same way).

Practical tip: wait for Clusters when you can, and use Fortune III for the best average gem rate while farming. Leave enough Type Gem Blocks attached to the core so the formation keeps producing new buds.

How to farm Type Gems in Cobblemon (Crystal Core method)

The best answer to how to farm Type Gems in Cobblemon is the Deepslate Crystal Core. It is the heart of every formation and the block that grows attached Type Gem buds over time.

Step-by-step Type Gem farm

1. Find a formation in an air-exposed Deepslate cave.
2. Mine the Deepslate Crystal Core with an Iron Pickaxe or better and bring it home.
3. Place the core somewhere you can easily check (base basement, mining hall, etc.).
4. Use Type Gems on the core to plant Small Type Gem Buds of the types you want.
5. Let buds mature into medium buds, large buds, clusters, and Type Gem Blocks.
6. Harvest mature clusters/blocks, then re-plant or leave growth running for a renewable loop.

Core farm rules you need to know

• A single Deepslate Crystal Core can support up to 7 connected Type Gem Blocks.
• Once that limit is hit, clusters stop blossoming into new blocks until you mine an existing block.
• Harvesting some blocks while leaving others attached keeps the farm productive instead of stalling.
• You can specialize a core (one type) or mix types depending on which TMs you are crafting.

This is the closest thing Cobblemon has to a true Type Gem factory — explore once, farm forever.

Type Gems from Alpha Pokémon and ruins

Alpha Pokémon drops

When you knock out Alpha Pokémon, they have a chance to drop a Type Gem matching one of their types. That makes Alpha KO farming a strong secondary gem source — especially while you are already hunting Alphas for Exp. Candies and IV candies.

Ruin loot

Type Gems also appear as exploration loot in ruin structures, including gilded chests and suspicious blocks. Ruins will not replace a Crystal Core farm, but they are a great early boost while you are still searching Deepslate caves for your first core.

Cobblemon Type Gem recipe (what you can actually craft)

There is no crafting recipe that creates Type Gems from scratch. When players search Cobblemon Type Gem recipe, they usually mean one of these:

1) Type Gem Block storage recipe

Craft 4 Type Gems of the same type into a matching Type Gem Block for compact storage and building. Mine the block later (Iron Pickaxe+) when you need gems back for TMs.

2) TM Machine recipes that consume Type Gems

Once a TM is unlocked (often by catching Pokémon / Alphas that know the move), you craft it at the TM Machine using the matching Type Gem plus the TM's other ingredients. Use the Alpha TMs tool to see which Alphas help unlock each move, then stockpile the correct gems for crafting.

3) Held-item crafts

Type Gems can also be crafted with wool and string into type-themed held items, and a raw Type Gem can be held to give a one-time +10% boost to the next move of that type (the gem is consumed).

Bottom line: you obtain Type Gems by mining, farming, Alphas, and ruins — then you spend them in TM / storage / held-item recipes.

Best uses for Type Gems

1. Craft TMs — the #1 reason to farm gems in Cobblemon 1.8.
2. Stockpile by type — keep chests labeled Fire, Dragon, Fairy, etc. so TM crafting stays fast.
3. Compact into Type Gem Blocks — saves inventory space and looks great in a gem storage room.
4. Situational held boosts — the 10% type boost is niche but useful for tough fights when gems are plentiful.

Quick Type Gem checklist

1. Explore Deepslate caves for a crystal formation.
2. Mine the Deepslate Crystal Core with an Iron Pickaxe or better.
3. Relocate the core to your base and plant the Type Gems you need.
4. Wait for clusters / blocks; harvest with Fortune when possible.
5. Keep at most 7 Type Gem Blocks connected per core so growth does not stall.
6. Supplement with Alpha KOs and ruin loot while exploring.
7. Spend gems at the TM Machine (and compact extras into Type Gem Blocks).
